UPS 54 kW

Description

Uninterruptible power supply unit is designed to provide consumers with regulated three-phase current in the event of power mains failure or poor quality of electric power. Operation time of UPS depends on the components.

Features

• Automatic transfer from external power to own batteries (AB) in the event of power mains failure or when the parameters are outside the limits;
• charge of own AB if external power network is available;
• power supply to consumers (regulated current) and simultaneous charge of own AB;
• automatic heating of batteries if external power is available.
