Review: Steady output and reliable - Works very well. I set the voltage adjust feature to get 12.006 volts on my Fluke meter and the value remains the same week after week. I put the power supply to good use running my Celestron C11 telescope without any problems. Review: excellent product. - Great operation and built well. This unit has a built in discharge when the unit is powered down, no stored voltage. The din rail mount is a little sloppy, allows the unit to shake around. Vibration might become an issue if you use it where vibration is an issue. The voltage adjustment is great to be able to boost voltage if needed, even by a 10th of a volt. It came set at exactly 12 volts, I'm running it at 13.2 and had no voltage drop under load. ## Features - Primary output voltage (vdc): 12 - Output current (a): 10 - Maximum output power (w): 120 - Family: edr-120 - Input voltage (vac): 90 to 264 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00R5CHZAO | | Best Sellers Rank | #353 in Computer Power Supplies | | Brand | MEAN WELL | | Compatible Devices | Personal Computer | | Connector Quantity | 1 | | Connector Type | ATX | | Connector Type Used on Cable | ATX | | Cooling Method | Air | | Current Rating | 10 Amps | | Customer Reviews | 4.7 out of 5 stars 213 Reviews | | Form Factor | DIN Rail | | Global Trade Identification Number | 00840406201799 | | Item Dimensions | 5.91 x 2.48 x 5.59 inches | | Item Type Name | Single Output DIN Rail Power Supply 12V 10A 120W | | Manufacturer | MEAN WELL | | Maximum Input Voltage | 264 Volts (AC) | | Mfr Part Number | EDR-120-12 | | Minimum Input Voltage | 90 Volts | | Model Name | EDR-120-12 | | Model Number | EDR-120-12 | | Output Wattage | 120 Watts | | Power Supply Design | DIN Rail Mounted | | System Bus Connector Type | ATX | | UPC | 610738126813 | | Unit Count | 1.0 Count | | Wattage | 120 watts | ## Product Details - **Brand:** MEAN WELL - **Compatible Devices:** Personal Computer - **Connector Type:** ATX - **Cooling Method:** Air - **Form Factor:** DIN Rail - **Item dimensions L x W x H:** 5.91 x 2.48 x 5.59 inches - **Model Name:** EDR-120-12 - **Output Wattage:** 120 Watts - **Power Supply Design:** DIN Rail Mounted - **Wattage:** 120 watts ## Images ![Mean Well EDR-120-12 Single Output DIN Rail Power Supply 12V 10 Amp 120W - Image 1](https://m.media-amazon.com/images/I/617y6q2hokL.jpg) ## Questions & Answers **Q: What's the difference between the edr- and the mdr- series?** A: The main difference is that the MDR series has a "DC OK Relay Contact" which monitors the output voltage compared to the EDR series which is not available. The EDR series is the Economical Slim DIN version and has an operating temperature of -20 deg C to +60 deg C compared to the MDR's -10 deg C to +60 deg C. The EDR has a 2 year warranty compared to the MDR's 3 year warranty. **Q: Can this be mounted and run flat on its back?** A: It clicks into the din rail and mounts as shown in the photo. Orientation would not affect Operation. **Q: The image shows a 5a supply. Description says 10a. Is this a 5a or 10a?** A: The EDR-120-12 will put out 10A, not 5A. The current photo (EDR-120-24) will be replaced with EDR-120-12 as soon as possible. **Q: I noticed this PSU has an adjust pin, how high may the voltage be adjusted to?** A: Hi TheSov,The voltage adjustment range is 12vdc to 14vdc. I'll include a datasheet link below.http://www.jameco.com/Jameco/Products/ProdDS/2218530.PDF ## Customer Reviews ### ⭐⭐⭐⭐⭐ Steady output and reliable *by R***N on June 21, 2025* Works very well.
