120W/48V Industrial DIN Rail Power Supply

GWS-DP120-48 is one economical slim 120W industrial DIN Rail power supply series, adapting to be installed on TS-35/7.5 or TS-35/15 mounting rails. The entire series adopts the full range AC input from 90VAC to 264VAC and conforms to EN61000-3-2, the norm the European Union regulates for harmonic current.

GWS-DP120-48 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 -40℃ to 70℃ 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 make GWS-DP120-48 a very competitive power supply solution for industrial applications.
