Uninterruptible Power Supply Systems


UPS are transformerless sources with dual power conversion that are designed to supply sine-wave 380/220V 50Hz alternating voltage to electric equipment via a three-phase four-wire system (GOST 13109-97) and protect it from any network failures, including distortion or loss of input voltage, and suppress high-voltage pulses and high-frequency interferences coming from the network.

The UPS additionally delivers voltage monitoring and grading on individual battery cells for the purpose of battery life extension.

The UPS are compatible with electric equipment with power recovery to the network.
