MHT 250
UPS
Description
Master HP (MHT) is a three-phase UPS designed to back up data centres and other mission-critical settings such as industrial environments, telecommunications networks, and sensitive electro-medical devices.
Scalable Solution
MHT offers the scope for multi-megawatt installations by enabling systems of up to 8 (distributed parallel) or 7 (centralised parallel) UPS. Hot System Expansion enables you to add UPS without transferring to bypass.
Galvanic Isolation
Incorporates an output isolation transformer that ensures complete galvanic isolation between the load and the DC battery power source. Master HP delivers up to 95.5% efficiency in ONLINE mode, comparable to many transformer-free solutions.
