The modular power supplies in MDRC design of the CP-D series (modular DIN rail components) can be optimally installed in distribution boards. This series includes devices with output voltages of 12 V DC and 24 V DC at an output current of 0.42 A to 4.2 A. Thanks to the high thermal efficiency and the associated low power loss and low heating, the devices can be operated without forced cooling. All devices have a U/I output characteristic (fold-forward behavior). The power supplies of the CP-D series are approved in accordance with all applicable international standards.
