MHE 500
UPS
Description
Master HE (MHE) combines maximum protection with exceptional efficiency in mission-critical applications such as data centres, electro-medical devices, telecoms networks and security systems. Can operate with or without a neutral connection.
Complete Galvanic Isolation
Incorporates an output isolation transformer as part of the inverter circuit, ensuring total galvanic isolation between the load and the DC battery power source. Transformer sits within the UPS’s cabinet so doesn’t require any additional floor space.
Proven Performance
Delivers high-quality unity power (kW = kVA) and up to 96.5% efficiency in ONLINE mode. Suitable for systems powered by generators or MV/LV transformers. Parallel multiple UPS together to increase capacity (8 units in parallel redundant N+1 or 7 units in a centralised system incorporating a static bypass cabinet (MSB).
