Ermak Uninterruptible Power Supply System for Continuous Power Supply

The ERMAC Uninterruptible Power Supply System (hereinafter referred to as ERMAC UPS) performs electric energy conversion, provides power supply in case of mains failure (or deviations of voltage, frequency, distortion of shape, noise, etc.) or for autonomous operation of equipment in the complete absence of power grids near the object, for example: communication equipment, automated control systems, relay protection equipment. Power supply of consumers is provided by DC voltage 24/48/60V and guaranteed AC voltage 220V, 50 Hz. The ERMAK UPS system itself can be powered both from the single-phase current system with voltage 220V and from the three-phase current system with voltage 380V.

Uninterrupted power supply is ensured by installing buffer batteries of appropriate capacity. ERMAK UPSs are designed for operation in closed heated and ventilated premises. Under these conditions it is guaranteed that the UPS ERMAC will provide fulfilment of all its characteristics in accordance with TU MRTSU.436133.001.
