Product Description: DC-Converter 344DH-24

The DC-DC Converter 344DH-24 is the successor to the DC-Converter 344-24-SD. It was specially developed for use in extreme environments and climatic conditions. The EMC properties have been further improved, the current and voltage control even better coordinated. This makes the 344DH-24 universally applicable as a 24VDC power supply. The realization of a customized DC-DC converter with significantly increased output power to e.g. 80W is possible. The type of consumers, whether inductive, capacitive, ohmic, or a combination thereof, e.g. consumers with backup batteries can be easily supplied. Please ask us for further adjustments!
