120W/48V Industrial DIN Rail Power Supply

HVT120-48 is one economical slim 120W industrial DIN Rail power supply series, adapted 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.

HVT120-48 is designed with a 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 a constant current mode for overload protection, fitting various inductive or capacitive applications. The complete protection functions and relevant certificates for industrial control apparatus make DP120-48 a very competitive power supply solution for industrial applications.
