Uninterrupted Motive Power Supply (UMPS)

Hitachi Hi-Rel offers a unique solution called UMPS (Uninterrupted Motive Power Supply) which carries out the function of providing power to load in case of blackout while at the same time does not require to be oversized in its rating. This is also an energy efficient solution as compared to conventional UPS.

Uninterrupted Motive Power Supply (UMPS) is the most reliable concept of providing Uninterrupted Power Backup to 3ph motor loads. In case of normal power availability, the UMPS continues to give on-line 3ph power to critical motor loads with double conversion of power and the batteries are also charged. In case of power failure, the charged battery continues to feed the motor through controlled inverter without any interruption to the load. The backup time is decided by the load and AH capacity of the battery.

• Efficient way to support Induction Motor Loads during Total Black Out
• Technically Superior Solution as compared to Standard UPS.
• Static Switch ensures Changeover of Load to Battery during Black Out
• Ensures Constant RPM till Battery Drains
• Cold Start even during Blackouts (Optional)
