Reliable power for a sustainable world
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 95.5% 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).
Choice of 10 power ratings
95.5% operating efficiency (ONLINE mode) reduces energy waste
Ideal for systems powered by generators or MV/LV transformers
Parallel up to 8 (distributed) or 7 (centralised) for extra capacity or redundancy
Efficiency Control System optimises efficiency in parallel installations
Ensures galvanic isolation
Enhanced battery care system ensures maximum battery lifespan
Step Up/Step Down converter reduces ripple current
Offering high efficiency and maximum power availability, the Master HE series provides proven protection across a range of mission-critical environments.
Choose from 10 power ratings (100-120-160-200-250-300-400-500-600-800 kVA). Delivers unity power (kW = kVA) and exceptional operating efficiency of up to 95.5% in ONLINE mode.

MHE delivers up to 95.5% operating efficiency in ONLINE mode, performance comparable with many transformerless UPS. It also offers high efficiency even when running at partial loads.
Hot System Expansion (HSE) allows you to add UPS into an existing system without the need to transfer to bypass or interrupt your critical protection, while our intuitive Efficiency Control System (ECS) ensures optimum performance in parallel installations.
Depending on the load, the ECS places some UPS into standby mode, sharing the work between the remainder, which run at a higher efficiency all while guaranteeing N+1 redundancy at all times.
Master HE incorporates several features designed to prolong battery life, including deep discharge protection and voltage compensation. Step-Up/Step-Down converter reduces ripple current.
Centralised parallel systems of up to 7 UPS incorporate a centralised static bypass cabinet (MSB) available in 4 power ratings (800-1200-2000-3000 kVA).
