Description
NDR-75 is one economical slim 75W Din rail power supply series, adapted 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 90 VAC to 264 VAC and conforms to BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current. NDR-75 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 -20°C and 70°C 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 (UL508, TUV BS EN/EN62368-1, etc.) make NDR-75 a very competitive power supply solution for industrial applications.

NOTE
- All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25°C of ambient temperature.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- Tolerance: includes set up tolerance, line regulation, and load regulation.
- The power supply is considered a component that will be installed into the final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
- Installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
- Derating may be needed under low input voltage. Please check the derating curve for more details.
- The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitudes higher than 2000m(6500ft).
