HatchPower HP33 Modular UPS
Scalable double-conversion power, module by module.
A hot-swappable modular UPS platform that grows in 50 kVA steps, keeps critical loads on double conversion at 97.6% efficiency and allows zero-downtime maintenance from the front of the cabinet.
Overview
Why this system exists
The HP33 is built for facilities that cannot afford a single point of failure. Instead of a monolithic block, capacity is delivered by 50 kVA power modules that share a common frame, static bypass and control bus. You buy the capacity you need today and add modules — not a new UPS — when the hall expands.
Each module carries its own rectifier, inverter and DSP controller. If one fails, the remaining modules instantly absorb the load and the faulty unit can be replaced from the front of the cabinet in under five minutes, without transferring to bypass. That is what "maintainable while online" actually means.
The HP33 is compatible with both VRLA and lithium-ion battery cabinets, supports a shared or dedicated battery bus, and reports through SNMP, Modbus TCP and dry contacts so it can be monitored by any BMS or DCIM platform.
