TDR-240 is one economical slim 240W Din Rail power supply series, adapted to be installed on TS-35/7.5 or TS-35/15 mounting rails.

The body is designed 63mm in width, which allows space saving inside the cabinets. The entire series adopts the full range AC input from 3 ψ 340VAC to 550VAC (Dual Phase operation possible) and conforms to EN61000-3-2, the norm the European Union regulates for harmonic current.

TDR-240 is designed with metal housing that enhances the unit’s power dissipation. With working efficiency up to 92%, the entire series can operate at the ambient temperature between -30°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 make TDR-240 a very competitive power supply solution for industrial applications.
