Power distribution and accessories
Power distribution and accessories
Everything that sits around the UPS: PDUs to get power to the equipment, isolation and conditioning for noisy circuits, bypass for service without downtime, battery cabinets for longer runtime, network cards for monitoring and portable cooling for hot rooms.
Power distribution
Rack PDUs, from basic outlet strips to switchable units with outlet-level metering and remote reboot.
Power conditioning
Isolation transformers and voltage regulation for noise, ground loops and unstable supply.
Bypass
Maintenance bypass, so the UPS can be serviced or replaced while the load stays powered.
Battery cabinets, connectivity and cooling
Longer runtime, network monitoring and spot cooling.
How to choose
| If you need | Start with |
|---|---|
| Reboot hung equipment remotely and see power at each outlet | SPDU |
| Simple outlet distribution in a rack | XPDU |
| Surge protection at the rack | XPDS |
| Hum, noise or ground loops on a small load | JX, connected after the UPS |
| Isolation or step-down for a rack, up to 10 kVA | Isolation PDU |
| Service the UPS without dropping the load | XBDM or XBDM HW |
| Monitor the UPS over the network | Web/SNMP card |
Frequently asked questions
What is the difference between a basic PDU and a smart PDU?
A basic PDU distributes power to outlets. A smart PDU adds metering and remote control, so you can see the load at each outlet and power-cycle a hung device from anywhere instead of sending someone to the site.
Where does an isolation transformer go?
After the UPS. The UPS feeds the isolation transformer, and the sensitive equipment plugs directly into the transformer. Putting another PDU or power strip after the transformer adds its own ground path and undoes the isolation.
Why install a maintenance bypass?
It lets you take the UPS completely out of the circuit for service or replacement while the load stays on utility power, instead of shutting the equipment down.
Which network card does my UPS need?
It depends on the UPS. The SNMP-2PG1 is the card for our modular and three-phase UPS, with SNMP, Modbus TCP and BACnet/IP. The Web/SNMP cards page lists the right card for each model.
