EDR-120-24 MEAN WELL 120W 24V Single Output Industrial DIN-Rail Power Supply
The EDR-120-24 MEAN WELL is an economical, slimline 120W AC/DC DIN-rail power supply engineered to provide stable 24V DC power to industrial control cabinets, automation panels, and marine telemetry enclosures. Delivering a continuous 24V DC output at 5A, the EDR-120-24 MEAN WELL features a narrow 40 mm wide metal housing designed to maximize rail space on standard TS-35/7.5 or TS-35/15 mounting tracks.
Equipped with a wide single-phase universal input range ($90–264\text{ VAC}$ / $127–370\text{ VDC}$), the EDR-120-24 MEAN WELL incorporates built-in active protection against short circuits, overloads, overvoltages, and overtemperatures. Featuring a high efficiency rating of up to 87.5% and free-air convection cooling across a wide temperature range (-20°C to +60°C), it serves as a highly reliable primary power source for PLCs, SCADA gateways, sensors, and field actuators.
Key Features of the EDR-120-24 MEAN WELL
-
High Power Density & Slim Footprint: 40 mm ultra-slim width saves valuable DIN-rail space inside crowded electrical enclosures and control boxes.
-
Universal Single-Phase Input: Operates on full-range $90–264\text{ VAC}$ ($47–63\text{ Hz}$) or $127–370\text{ VDC}$ input without requiring manual selector switches.
-
Adjustable Output Voltage: Front-panel trimming potentiometer allows output voltage adjustment from 24V to 28V DC to compensate for wire voltage drops.
-
Comprehensive Circuit Protection: Features constant current limiting for overload protection, auto-recovery short circuit protection, overvoltage cutoff, and thermal shutdown.
-
Free-Air Convection Cooling: Heavy-duty perforated metal casing ensures efficient heat dissipation without noise-generating or failure-prone cooling fans.
-
Industrial Safety Compliance: Certified according to UL508, EN62368-1, and BS EN/EN55032 (Class A) standards for industrial control hardware.
Primary Applications
-
Industrial Automation & PLC Panels: Powering 24V DC programmable logic controllers, remote I/O modules, HMIs, and relay banks
-
Marine & Vessel SCADA Enclosures: Supplying stabilized power to engine telemetry monitoring devices, CAN-bus gateways, and sensors
-
Factory Control Cabinets: Providing continuous 24V DC bus voltage for solenoid valves, motor drives, sensors, and safety interlocks
