■Model Encoding
■Description
NDR-120 is one economical slim 120W DIN rail power supply series, adapt to be installed on TS-35/7.5
or TS-35/15 mounting rails. The body is designed 40mm in width, which allows space saving inside the
cabinets. 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.
NDR-120 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 -20 and 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 (UL508, TUV EN60950-1, and etc.) make NDR-120 a very competitive power supply solution for
industrial applications.

VOLTAGE TOLERANCE
Note.3
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.℃
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets
EMC directives.
5. 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.
6. Derating may be needed under low input voltage. Please check the derating curve for more details.
