The NDR-480 series is an economical slim 480 W Din rail power supply series that can be installed on TS-35/7.5 or TS-35/15 mounting rails. With a body width of 85.5 mm, the device allows space saving @@@inside the cabinets. The series adopts the full range AC input from 90 VAC to 264 VAC and conforms to EN61000-3-2, the norm the European Union regulates for harmonic current. NDR-480 has a metal housing to enhance power dissipation. With working efficiency up to 93%, the 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. Its protection functions and relevant certificates for industrial control apparatus (UL508, TUV EN60950-1, etc.) make the NDR-480 a very competitive power supply solution for industrial applications.
