Power Supply Unit MEAN WELL MDR-100-24

The MEAN WELL MDR-100-24 is a compact DIN-rail mounted power supply that delivers up to 96 W output power with a nominal 24 V DC output. It accepts a universal AC input from 85 to 264 V at 47–63 Hz and is designed for continuous industrial and commercial use. The unit features convection cooling, low no-load power consumption and a DC OK relay contact for remote status monitoring.

Advantages

The MDR-100-24 incorporates ZCS/ZVS topology to reduce power dissipation and improve efficiency, includes multiple protections against short circuit, overload, over-voltage and over-temperature, and provides an LED power-on indicator. It is designed for installation on a TS-35/7.5 or 15 DIN rail and is factory burn-in tested at full load for reliability. No-load power consumption is less than 1 W.

Suitable for

• Industrial control cabinets and automation equipment
• Building management and HVAC systems
• Telecommunications and networking devices
• Peripheral devices and instrumentation requiring 24 V DC
