Certified with UL508 and TUV EN60950-1 for safety, this power supply is ideal for various applications.

## Long description

The MEAN WELL SDR-75-24 77W Metallic is a compact industrial power supply delivering 24V DC output with continuous 77W power and a peak capability up to 150% for short durations. Designed for DIN-rail mounting in control cabinets, it accepts a wide AC input range from 88 to 264V and offers high energy conversion with up to 90% efficiency. The metal housing and convection cooling enable silent operation without fans, while safety certifications for industrial environments ensure compliance with relevant standards.
Advantages
This power supply combines compact dimensions with robust performance: a narrow 32 mm width allows dense installation in control panels, and the 77W continuous output with 150% peak load supports demanding startup or inrush current conditions. High efficiency and low dissipation reduce heat generation, improving reliability and lowering ambient temperature stress. The unit passes a 100% full load burn-in test and has a high MTBF, contributing to long service life. Mounting on standard TS-35/7.5 or 15 DIN rails simplifies integration and maintenance.
Suitable for
Industrial automation control cabinets
Signal and communication equipment
PLC and I/O modules
Machine and process control systems
Remote monitoring and instrumentation

How to use
Install the unit on a compatible TS-35 DIN rail inside a properly ventilated enclosure. Connect the AC supply to the input terminals observing polarity and protective earth connection. Connect the 24V DC load to the output terminals, ensuring total load does not exceed the continuous 77W rating during normal operation; account for short-term peak capability when sizing for inrush currents. Verify installation against applicable electrical codes and the equipment's safety documentation before powering on.
Usage recommendations
Place the power supply where airflow is unobstructed to maintain convection cooling; avoid mounting next to heat sources. For stable operation, keep ambient temperature within the device's specified operating range and ensure connectors are tightened to recommended torque. Use appropriate fusing on the input and output circuits and follow local regulations for grounding and protective devices.
