DIN Rail and Panel Mount Lithium UPS
A DIN rail mounted UPS that actually fits the panel. The J60-350 is 1.25 inches thick and weighs 3.4 pounds (the J60-600 is 1.6 inches and 4.7 pounds), thin and light enough to mount on standard 35mm DIN rail alongside the PLCs, I/O modules, and terminal blocks it protects. Panel builders, machine builders, and system integrators specify it because it is a true AC UPS in a DIN mount form factor, not a scaled-down tower. LiFePO₄ battery, 50°C operation, up to 15-year service life, completely fanless.
What is a DIN rail UPS, and why mount one in the panel?
Conventional UPS systems don’t fit in control panels. The J60 was designed from the ground up for embedded industrial installation: the form factor, the battery chemistry, the thermal design, and the mounting options are all specific to this application.
At 1.25 inches and 3.4 lbs (J60-350) or 1.6 inches and 4.7 lbs (J60-600), the J60 occupies minimal space on a DIN rail or panel surface. Standard 35mm DIN rail mounting with the optional J60-DIN kit, the same rail your PLCs, terminals, and I/O modules use.
LiFePO₄ (lithium iron phosphate) batteries are rated for 3,000-5,000 discharge cycles and up to 15 years service life in ideal conditions. That is 3 to 4 times the life of VRLA, so battery replacement inside a running control panel largely goes away. In the field, 95% of J60-series batteries are still above 80% capacity after 10 years.
Industrial enclosures and electrical rooms frequently exceed 35-40°C. The J60 operates reliably to 50°C with capacity derating above 40°C. Lead acid batteries in the same environment would see accelerated aging and significantly shortened service life.
No fan means no airflow path for dust, metal particles, or contaminants into the UPS. The J60’s passive cooling design requires no filter maintenance and eliminates fan failure as a failure mode, which matters in dusty factory and fabrication environments.
The J60 automatically powers back on when utility power is restored, with no manual intervention required. Control panels running unattended in remote or unmanned locations maintain continuous protection without operator action after a power event.
High conversion efficiency reduces heat generation inside the enclosure, which matters in thermally constrained control panels where every watt of waste heat must be managed. Lower heat output also contributes to longer component service life in sealed enclosures.
DIN rail UPS 120V and 230V models
Four models cover 120V and 230V at 350VA and 600VA. The 600VA models (J60-600 and J60i-600) add optional SNMP/Web monitoring and remote reboot capability via the SNMP-J60 card.

DIN rail mount, panel mount, and wall mount
Three mounting options cover every industrial installation scenario. DIN rail mounting is the most common for new panel builds; panel mount and flat mount suit retrofit installations and space-constrained enclosures. Whether you call it a DIN rail mounted UPS, a DIN mount UPS, or a panel mount UPS, it is the same unit and the same kit.
-
01
DIN rail mount: uses the optional J60-DIN Mounting Kit. Clips directly onto standard 35mm DIN rails alongside PLCs, terminal blocks, I/O modules, and other rail-mounted components. No panel cutout or additional hardware required beyond the kit.
-
02
Panel mount / wall mount: mounts flat against any panel, backplate, or wall surface using the integrated mounting slots, with no kit required. This is the option to use when the rail is already full, when the enclosure has backplate space but no spare rail, or when a panel mount UPS is simply the cleaner layout.
-
03
Flat surface: sits horizontally on any flat surface inside or alongside equipment. Useful for temporary installations, OEM integration, or applications where fixed mounting isn’t required.
DIN rail mounting kit (J60-DIN) is sold separately. Confirm kit availability with the product page or contact Xtreme Power for OEM orders.
Converting an existing cabinet from lead acid to lithium
Most J60 installations are not new panel builds. They are cabinets that already have a UPS in them, and the sealed lead-acid battery has reached the end of its third or fourth replacement cycle. The conversion is usually straightforward, and it removes a recurring service cost rather than deferring it.
- 01It almost always fits: at 1.25 to 1.6 inches thick and 3.4 to 4.7 lbs, the J60 generally goes in where a VRLA unit came out with room left over. Panel mount needs no rail space at all, so a full rail is not a blocker.
- 02Check three things first: depth available in the enclosure, the actual load in Watts against the 200W (350VA) or 360W (600VA) rating, and continuous ambient temperature. The J60 is rated to 50°C, with warranty derating above 40°C continuous.
- 03The battery cycle goes away: LiFePO₄ is rated 3,000–5,000 cycles and up to 15 years, against the 3–5 years a VRLA unit gets in the same cabinet. On a fleet of panels, that is the difference between a standing replacement program and leaving them alone.
- 04It is a true AC UPS: AC in, AC out, with battery backup. Not a 24 VDC buffer, hold-up, or redundancy module; those live on the DC side of a 24V supply and solve a different problem. If the load runs on AC, this is the right category.
Runtime by load: J60-600 / J60i-600 (360W max)
Runtime depends on actual load, and PLC and automation loads are typically well below nameplate maximum, which means real-world runtime is often significantly longer than the minimum. A 40W PLC load on a J60-600 runs about an hour (64 minutes).
| Load | Runtime | Typical application |
|---|---|---|
| 30W | 86 minutes | IoT device, remote monitoring node |
| 40W | 64 minutes | Compact PLC, gateway, or sensor controller |
| 80W | 35 minutes | Small PLC or industrial PC |
| 120W | 23 minutes | Industrial PC with peripherals |
| 200W | 14 minutes | Mid-size PLC with I/O and HMI |
| 360W (full load) | 6 minutes | Maximum rated load |

Optional SNMP and web monitoring
The optional Web/SNMP Card (SNMP-J60) adds full remote management to the J60-600 and J60i-600. The 350VA models do not support this option. When installed, it enables:
- Real-time voltage, load, and battery health monitoring
- Remote output power control and device reboot
- Alarm notifications and event logging
- SNMP integration with network management systems
- Web-based management interface
- Optional EMD-J60 environmental sensor for temperature and humidity monitoring
Where a panel mount UPS gets specified
Keeps PLCs, I/O modules, relays, and control system components running during brief power disturbances. A 10-second power interruption that causes a PLC to reboot can require minutes of manual recovery in a production environment.
Panel PCs, touchscreen HMIs, and operator terminals, often installed in the same control cabinet as the PLC, need the same power protection. The J60’s thin profile leaves room for the equipment it protects.
Industrial PCs, embedded computing platforms, and data acquisition systems benefit from the J60’s ability to provide clean power and bridge brief outages without corrupting running processes or logged data.
Remote monitoring nodes, IoT gateways, and field communication devices often operate in enclosures far from grid-quality power. Runtime of over an hour at 30–40W on the J60-600, plus automatic restart, makes it well-suited for unattended field installations.
Machine builders and OEM equipment manufacturers integrate the J60 into standard control cabinet builds. The DIN rail mounting standardizes installation, and the battery is rated for up to 15 years.
Compact edge computing devices such as industrial PCs, protocol converters, and communication gateways often live in the same enclosure as the equipment they serve. The J60’s small footprint and long battery life suit these co-located deployments.
Optical network terminals in zone boxes and enclosures
The same mounting problem turns up outside the control panel. In a passive optical LAN the floor closet is designed out, and an optical network terminal is installed in a ceiling zone box, a wall cavity, or a furniture raceway, none of which will take a conventional tower UPS. DIN rail and panel mounting put the backup power inside the same enclosure as the ONT. Sizing differs from an automation load in one important way: a bare ONT draws under 10 W, but an ONT sourcing Power over Ethernet to an access point or camera can draw 70 W or more, and all of it passes through the UPS.
Certifications
5-year warranty covering electronics and battery in the USA and Canada; 2 years depot repair elsewhere. Warranty is reduced to 2 years for installations where ambient temperature continuously exceeds 40°C and is below 50°C. The J60 is not rated for ambient temperatures above 50°C.
In the USA and Canada the 120V J60 carries a $25,000 connected-equipment load protection policy; register within 10 days of purchase. The J60i is not covered.
Common questions about DIN rail and panel mount UPS
What is a DIN rail UPS?
A DIN rail UPS is an uninterruptible power supply built to mount on the standard 35mm rail inside a control panel or enclosure, rather than sitting on a floor or in a rack. It lets the backup power live in the same cabinet as the PLC, I/O modules, and terminal blocks it protects. The J60 mounts to 35mm rail with the optional J60-DIN kit, and also supports panel, wall, and flat mounting without it.
Is this an AC UPS or a DC buffer module?
It is a true AC UPS. The J60 takes AC input and delivers AC output with battery backup, so it protects equipment that plugs into a normal outlet or terminal. It is not a 24 VDC buffer, hold-up, or redundancy module; those sit on the DC side of a 24V power supply and serve a different purpose. If the load is a PLC, HMI, industrial PC, switch, or gateway running on AC, the J60 is the right category.
What makes the J60 different from other compact UPS systems?
It is built for embedded industrial installation: 1.25 inches thick on the 350VA model and 1.6 inches on the 600VA, DIN rail compatible, fanless, and rated to 50°C. Most compact UPS systems are scaled-down rack or tower designs. The J60’s LiFePO₄ battery is rated for up to 15 years, 3 to 4 times the life of VRLA.
Can the J60 be mounted on a DIN rail?
Yes. The optional J60-DIN Mounting Kit, sold separately, mounts it on standard 35mm DIN rail alongside PLCs, terminal blocks, and I/O modules. Panel, wall, and flat mounting need no kit.
What is the backup runtime of the J60?
On the J60-600, about 6 minutes at full load (360W), 14 minutes at 200W, 23 minutes at 120W, 35 minutes at 80W, 64 minutes at 40W and 86 minutes at 30W. Most PLC and automation loads are well below nameplate. Use the UPS sizing tool for your specific load.
Can I replace a VRLA UPS in an existing cabinet with lithium?
Usually yes, and it is one of the most common reasons people specify the J60. At 1.25 to 1.6 inches thick it generally fits where a sealed lead-acid unit came out, and it removes the 3 to 5 year battery replacement cycle. Check three things first: available depth, the load in Watts against the 200W or 360W rating, and ambient temperature, since the J60 is rated to 50°C with warranty derating above 40°C.
How long does the lithium battery last, and what is the warranty?
LiFePO₄ batteries in the J60 are rated for 3,000 to 5,000 cycles and up to 15 years in ideal conditions. Warranty is 5 years in the USA and Canada at or below 40°C ambient, 2 years for continuous operation between 40 and 50°C, and 2 years depot repair elsewhere. In the USA and Canada the 120V J60 also carries a $25,000 load protection policy.
Is the J60 certified for industrial and government use?
Yes. The J60 (120V) is UL-1778 listed, cTUVus, FCC Class A, RoHS and TAA compliant. The J60i (230V) carries CE, IEC/EN 61000-3-2 Class A and RoHS and is TAA compliant. TAA compliance supports federal, VA, state, and municipal procurement without a waiver.
Can I monitor and control the J60 remotely?
Yes, on the 600VA models (J60-600 and J60i-600) with the optional SNMP-J60 Web/SNMP card: power metrics, alarms, remote output control and reboot. The 350VA models do not support the card.
Are there 230V models available?
Yes. The J60i-350 and J60i-600 are 230V models for international and 230V industrial installations. They use the same DIN rail kit and share the form factor and battery chemistry of the 120V J60.
