Power Compact Series Power Compact combines the basic functionality of an economic switched mode power supply with key additional features to ensure high system availability.These power supply units are suitable for a highly diverse range of applications in solar, measurement and control technology and they really come into their own in industrial and building automation. The devices cover the average power requirement from 120 W to 480 W. The output voltage can be set easily using the rotary potentiometer on the front of the housing. The robust DIN rail fastening method and push-in connection terminals enable fast and secure mounting. Advantages Stabilised and adjustable output voltageFast tripping of standard bi-metal circuit breakersDC OK signal contactParallel operationPush-in terminalsRobust DIN rail mountingResistant to transient over voltages up to 4 kVApprovals cURus, cULus, GL (Lloyds Registered)

The control- and isolating transformer, offers very good switch-on behaviour with reduced starting currents, high power density, primary side voltage adjustment tappings, excellent corrosion protection, and low noise. It is designed for use as a control transformer for electrical isolation and as an isolating transformer for safe electrical isolation. It is also suitable for creating SELV and PELV circuits due to output voltage limits. Very good switch-on behaviour with reduced starting currentsHigh power density with compact construction designPrimary side voltage adjustment tappingsExcellent corrosion protection and low noiseSuitable for creating SELV and PELV circuitsRobust metal footplate for simple mounting
