NDR-75 is one economical slim 75W DIN rail power supply series adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 32mm in width which allows space saving inside the cabinets. The entire series adopts the full range AC input from 90VAC to 264VAC and conforms to EN6100-3-2 the norm the European Union regulates for harmonic current. NDR-75 is designed with metal housing that enhances the unit's power dissipation. With working efficiency up to 89% the entire series can operate at the ambient temperature between -20°C and 70°C under air convection. It is equipped with constant current mode for over-load protection fitting various inductive or capacitive applications. The complete protection functions and relevant certificates for industrial control apparatus (UL508 TUV EN60950-1 and etc.) make NDR-75 a very competitive power supply solution for industrial applications.
