KSB 04012 Buffer Power Supply 230/12VDC 2.9A 17000-2288

The KSB series of stabilized, switch-mode buffer power supplies, housed in a DIN rail mounting enclosure, are designed for use in installations requiring uninterrupted power. They allow simultaneous powering of loads from the AC mains and charging of a battery, and in the event of a mains power failure, they automatically switch to battery mode. Built-in short-circuit, overvoltage, and overload protection, as well as battery protection, increase reliability and safety. The power supplies are equipped with convection cooling, LED indicators, and signal outputs, which facilitate their integration and monitoring in automation systems, security systems, and industrial installations.
