MEAN WELL MDR Series Ultra-Slim Industrial DIN Rail Power Supply
Complete Portfolio: 10W to 96W | Space-Saving Profile | DC OK Signal | Class I, Div 2 Certified
Compact Reliability for Industrial Cabinets
The MEAN WELL MDR Series is a highly dependable line of ultra-slim DIN rail power supplies. Designed to minimize footprint in crowded industrial control cabinets, this series provides stable DC power ranging from 10W up to nearly 100W.
Core Industrial Advantages
- Ultra-Slim Form Factor: With widths starting at just 22.5mm and maxing out at 55mm, the MDR series saves critical space on TS-35/7.5 and TS-35/15 DIN rails.
- Energy Efficient: Features low no-load power consumption (less than 0.75W for <60W models, and <1W for 100W models), meeting modern energy-saving demands.
- System Monitoring: Every model is equipped with a built-in "DC OK" signal (either active signal or relay contact) for easy integration into control and alarm systems.
- Hazardous Location Ready: The 40W and 60W models are specially certified for Class I, Div 2 Hazardous Locations (T4 rating), ensuring safety in volatile environments.
MDR-10 & MDR-20 Specifications
The entry-level models are exceptionally narrow (only 22.5mm wide) and are perfect for powering small sensors, relays, and basic automation logic circuits.
| Model Series | Max Rated Power | DC Output Voltages | Efficiency (Max) | DC OK Signal Type |
|---|---|---|---|---|
| MDR-10 | 10W | 5V, 12V, 15V, 24V | 84% | Active Signal |
| MDR-20 | 24W (15W for 5V) | 5V, 12V, 15V, 24V | 84% | Active Signal |
MDR-40 & MDR-60 Specifications
Stepping up in power, the 40W and 60W units maintain a slim 40mm width while adding specialized safety certifications for hazardous industrial sites.
| Model Series | Max Rated Power | DC Output Voltages | Efficiency (Max) | Special Certifications |
|---|---|---|---|---|
| MDR-40 | 40.8W (30W for 5V) | 5V, 12V, 24V, 48V | 88% | Class I, Div 2 (HazLoc) |
| MDR-60 | 60W (50W for 5V) | 5V, 12V, 24V, 48V | 87% | Class I, Div 2 (HazLoc) |
MDR-100 Specifications
The flagship of the MDR series delivers nearly 100W of power while incorporating advanced topologies and active power factor correction (PFC) into a 55mm chassis.
| Model Series | Max Rated Power | DC Output Voltages | Efficiency (Max) | Active PFC |
|---|---|---|---|---|
| MDR-100 | 96W (90W for 12V) | 12V, 24V, 48V | 87% | Built-in (PF > 0.95 @ 230VAC) |
Advanced Technologies (MDR-100)
- ZCS/ZVS Technology: Utilizes Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS) to significantly reduce internal power dissipation, keeping the unit cool and reliable.
- High Power Factor: Integrated active PFC ensures compliance with stringent global energy harmonic standards (EN61000-3-2).
- Relay Alarm: Like the mid-power models, it includes a robust 30V/1A relay contact for DC OK monitoring.
Dimensions & System Integration
Physical Dimensions (W * H * D)
- MDR-10: 22.5 * 90 * 100 mm
- MDR-20: 22.5 * 90 * 100 mm
- MDR-40: 40 * 90 * 100 mm
- MDR-60: 40 * 90 * 100 mm
- MDR-100: 55 * 90 * 100 mm
Comprehensive Protections
- Short Circuit & Overload: Operates primarily in hiccup mode or constant current limiting, protecting the unit from damage and automatically recovering once the fault is removed.
- Over Voltage: Shuts down the output voltage (requires re-power on to recover for higher wattage models, or clamped via zener diode on lower wattage models).
- Over Temperature: (Specifically noted on MDR-100) Shuts down output voltage and auto-recovers after temperatures drop.
