Two power supplies, two very different jobs. A Mean Well supply built for industrial controls, alongside a compact door access controller designed to power and time electric locks. The wrong choice means voltage that doesn't match-or a lock that doesn't release. In the industrial power supplies transformers space, this decision comes up constantly.
Quick Verdict
Choose the Mean Well EDR-120-24 for panel installations where the higher DC output is required. Choose the access control supply for door lock wiring. The access control model costs $12.69, which is $15.31 below the Mean Well's $28.00 price, but the lower price only helps if the output matches your load.
Comparison Table
| Spec | Mean Well EDR-120-24 | 12V 3A Access Control Supply |
|---|---|---|
| Output | 24VDC, 5A, 120W | 12VDC, 3A, 30W |
| Input | 100-240VAC | 110-240VAC, 50-60Hz |
| Form factor | DIN rail | Grey controller |
| Price | $28.00 | $12.69 |
Where Each Product Wins
Where the Mean Well wins: It delivers a robust power output in a package designed for panel mounting, with enough current headroom for multiple loads.
Where the access control supply wins: It bundles an adjustable delay and NO/NC wiring support, directly handling the timing and lock control that door access installations need.
Product Notes
DIN Rail Power Supply, EDR-120-24, Mean Well, 24VDC \, 5A, 120W,Input :100-240VAC
This Mean Well unit brings a true DIN rail form factor plus a 24V DC output rated at 5A, which works out to 120W of continuous power. The EDR-120-24 model name carries the key specs: 120 for wattage and 24 for voltage, so you know exactly what it delivers. The 100-240VAC input means it can accept standard mains voltages commonly found in industrial settings. When you're assembling a control panel with DIN rail, this supply clips directly onto the rail and keeps wiring tidy. For systems already built around DIN rail, there is no need for extra brackets. Its main limitation is the higher price relative to the access control model, and the 24V output won't power 12V hardware without a separate converter.
12V 3A Power Supply Control for Door Access Control Access Control Power Supply
This grey controller supplies 12V DC at up to 3A, giving you 30W for door access equipment. The adjustable 0-15s delay is the standout feature, allowing you to set how long a lock stays released after the exit button is pressed. The NO/NC wiring modes provide compatibility with different lock configurations, and the pluggable green terminal block simplifies installation. The spray-painted grey housing and compact footprint let it sit discreetly near the lock controller. Its limitation is the 30W capacity and 12V output: if your setup needs more current or a higher voltage, this controller isn't the right fit. The package includes a Chinese & English manual, which helps with first-time wiring.
Final Choice by Use Case
Choose the Mean Well EDR-120-24 when you're assembling a panel and need the higher DC output for multiple devices. Choose the access control supply when you're wiring electric locks or electromagnetic locks. If your load needs the higher voltage, the Mean Well unit is the match. If your load expects a lower-voltage feed, the access controller is the purpose-built pick.
