UPS 20 kW

Description

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

Features

• Automatic switching from external power to own accumulator batteries (AB) in the event of power mains failure or power shutdown;
• Charge of own batteries when external power mains is available;
• Power supply of consumers with regulated current and simultaneous charge of own batteries;
• Automatic heating of AB when external power is available.
