ABB GE Critical Power LP33 Series — Discontinued
The ABB GE Critical Power LP33 Series has reached end-of-life — ending manufacturer support, parts availability, and firmware updates. For facilities relying on LP33 systems to protect mission-critical infrastructure, that discontinuation creates an urgent need to evaluate a modern replacement.
XPCC recommends the M90U Modular UPS Series — a high-efficiency, scalable, fully supported power-protection platform built for today’s critical-power demands. Whether you run a data center, healthcare facility, or industrial environment, replacing aging LP33 units with a next-generation modular UPS means higher uptime, lower maintenance costs, and long-term peace of mind.
Why this matters. The ABB GE Critical Power LP33 Series was officially designated End-of-Life in 2023. ABB GE has ceased manufacturing and full factory support — so replacement parts, batteries, and firmware are increasingly difficult to obtain.
ABB GE Critical LP33 replacement — the M90U family
The Xtreme Power M90U and M90U-80 family delivers reliable, high-efficiency backup power for mission-critical applications. With unity power factor (kVA = kW), you get maximum usable power without oversizing the UPS.
Scalable from 15 kVA up to 140 kVA N+1 at 208/120V, the M90U family offers remarkable flexibility in both capacity and redundancy.
Built for mission-critical power
kVA = kW ensures 100% utilization of UPS capacity, eliminating the need to oversize.
Configure from 15 kW up to 140 kW N+1 with hot-swappable power modules to meet dynamic needs.
Built-in bypass switch enables safe, uninterrupted servicing — no expensive external bypass.
Industry-leading power density minimizes floor space for data centers and mission-critical sites.
UL-1778, cUL, FCC Class A, RoHS, and TAA on select models.
Internal, hot-swappable battery modules with configurable runtime options.
Choose the right LP33 replacement
M90U
- Up to three hot-swappable 15 kVA/15 kW or 20 kVA/20 kW power modules
- Internal, easy-to-swap battery modules
- Economical compact modular platform
M90U-80
- Up to 80 kW UPS with batteries and bypass in a single compact cabinet
- Hot-swappable power and battery modules
- Large touch LCD
M90U-140
- Up to 140 kW N+1 UPS with batteries and bypass in a single cabinet
- Pair with the modular M90-BC battery cabinet for an industry-leading footprint
- Maximum capacity and redundancy in one platform
Why choose the M90U over the LP33?
Compared to the ABB GE LP33, the M90U family offers:
- Greater scalability — grow from 15 kVA to 140 kVA N+1 within the same product family
- Hot-swappable modules — simplify maintenance and minimize downtime
- Improved efficiency & power density — unity power factor maximizes usable power while reducing energy costs
- Lower installation costs — integrated maintenance bypass and optional receptacle panels reduce external components
ABB GE LP33 vs. XPC M90U
When transitioning from the discontinued LP33 Series, it helps to see the key technical differences. The M90U is designed to not only replace, but outperform legacy LP33 models across key metrics.
| Feature / Specification | ABB GE LP33 Series | XPC M90U Series |
|---|---|---|
| Power ratings | 10–100 kVA | 15–140 kVA (modular, scalable) |
| Input voltage range | 208V | 208V |
| Output voltage | 208V | 208V |
| Power factor | 0.9 | Unity (1.0) |
| Efficiency (online mode) | ~90–92% | Up to 94% (double conversion) |
| Scalability | Fixed capacity | Modular, scalable in 15 or 20 kVA blocks |
| Battery type | VRLA (sealed lead-acid) | VRLA (sealed lead-acid) |
| Battery runtime | Limited (fixed) | Configurable runtime options |
| Redundancy support | Limited | N+1, N+X modular redundancy |
| Maintenance requirements | High (end-of-life components) | Low (hot-swappable modules) |
| Form factor | Floor-standing tower | Compact, space-saving modular cabinet |
| Compliance / certifications | UL 1778, FCC Class A | UL 1778, RoHS, FCC Class A |
⚠ Note: As ABB GE LP33 Series units approach end-of-life, replacement parts, batteries, and firmware support may become increasingly difficult to obtain.
Where the M90U excels
The M90U is engineered for mission-critical operations that demand uninterrupted, clean, efficient power — suitable for new deployments and direct LP33 replacements alike.
Protects network, storage, and critical data; scales with growth or consolidation.
Powers life-saving equipment, diagnostics, and EMR with zero tolerance for downtime.
24/7 power for mobile networks, switching stations, and broadband systems.
Supports production lines, PLCs, and robotic systems to prevent costly interruptions.
Maintains uptime for transaction systems, trading platforms, and security operations.
Meets critical-infrastructure standards for secure, resilient power.
Keeps airport systems, railways, and traffic control powered during outages.
What you gain in day-to-day operation
- Zero-downtime switchover — hot-swappable modules and real-time load balancing
- High power density — more power per square foot than legacy systems like the LP33
- Future-proofing — modular design expands capacity without replacing the entire unit
- Energy savings — up to 30% lower energy loss compared to older double-conversion systems
Whether you’re upgrading a legacy ABB GE LP33 installation or designing a new critical-power environment, the M90U delivers flexibility, reliability, and performance.
