General Description

 

The Force-GT Series DIN rail industrial power supply features high power density and high efficiency. The Series offers overcurrent 

protection in constant current mode, making it suitable for charging applications. Conformal coating is applied on the PCBAs to protect 

against dust and pollutants often found in harsh industrial environments. The Series’ electromagnetic radiated and conducted emissions 

are compliant with heavy industrial Class B Emission standard and Immunity standard, and complies with environmental protection 

standards RoHS Directive.
