Overview

EDR-120-12 is the 12V output model of this series: rated current 10A, rated power 120W, typical efficiency 85%.

EDR-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 BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current. EDR-120 is designed with metal housing that enhances the unit's power dissipation. With working efficiency up to 88.5%, the entire series can operate at the ambient temperature between -20℃ and 60℃ 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 BS EN/EN62368-1, and etc.) make EDR-120 a very competitive power supply solution for industrial applications.

Test conditions and notes8

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 0.1μF & 47μF 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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
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.
7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
8. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

What is the difference between the EDR-120-12, EDR-120-24, and EDR-120-48?

All three are 120W slim DIN rail power supplies in the same 125.2 × 113.5 × 40mm enclosure with 90–264VAC universal input. The EDR-120-12 outputs 12V at 10A, the EDR-120-24 outputs 24V at 5A, and the EDR-120-48 outputs 48V at 2.5A. Choose the voltage that matches your load equipment's rated input.

Is the EDR-120-12 suitable for relay and sensor circuits in control panels?

Yes. The EDR-120-12 delivers 12V DC at 10A (120W), which is the standard voltage for many industrial relays, proximity sensors, and low-voltage control circuits. It mounts on standard DIN rail with a slim 40mm profile and complies with EMC EN55032 Class A for low electromagnetic interference.

Can the EDR-120-12 power a 12V CCTV or security camera system?

Yes. The EDR-120-12 provides 12V DC at up to 10A (120W), suitable for multi-camera CCTV installations in control rooms or equipment cabinets. It accepts 90–264VAC universal input and is approved to UL508, TÜV BS EN/EN62368-1, EAC and BSMI standards.

Can the EDR-120-12 be used inside an enclosed control cabinet?

Yes, it is designed for DIN rail mounting (TS35/7.5 or TS35/15) inside control panels and electrical cabinets. It operates in ambient temperatures from −20°C to +60°C, with load derating at higher temperatures per the derating curve. Ensure adequate ventilation: 40mm above, 20mm below and 5mm on each side is recommended at permanent full load.
