Description

Designed for critical applications in radio telecommunications, networking, automation, industrial processes, and emergency systems, this Microset stabilized power supply delivers 56 V DC, 20 A continuous current, and a peak current of 35 A for one second. Its 1200 W power rating and efficiency exceeding 92 percent ensure high performance, while the IP20 aluminum case allows for DIN rail installation.

The two output channels power the load and connect an external battery with floating polarity. When mains power is available, the system powers the load and automatically recharges the battery; during a blackout, the battery takes over without interruption. The controller disconnects the load and the battery when the discharge limit is reached, with automatic resetting when the mains supply is restored.
