The switched mode power supplies from ifm electronic offer both value and performance. They come in two designs: BasicLine in a compact plastic housing and ClassicLine in a robust metal housing. Both designs require only a small space on the DIN rail due to their slim housing. The power supplies start after power-on, even without minimum load, and are short-circuit proof and overload protected. Two LEDs and a DCok output signal the operating states. With their wide input voltage range and cULus approval they can be used worldwide.
Besides the long mains buffering time of up to 400 ms, another special feature of the ClassicLine is the intelligent power reserve. At a 1,5-fold nominal load the power supplies can provide extra current for 5 seconds and
for a longer time in case of lower overload. This additional power allows even difficult loads to start, for example motors and DC/DC converters. The input voltage range is from 100 to 240 V AC ±10% and the output voltage of the 24 V DC power supplies can be set from 24 to 28 V. Special types are available for the AS-Interface fieldbus system. These have an integrated data decoupling and a constant current characteristic.
