Information about the MEAN WELL SDR-120-24
The MEAN WELL SDR-120-24 is a premier industrial-grade DIN rail power supply engineered for superior efficiency and space-saving performance. A standout feature of this model is its 150% peak load capability, allowing the unit to deliver up to 180W for 3 seconds. This power reserve is critical for starting demanding inductive loads, such as DC motors or heavy-duty relays, without causing system-wide voltage drops or premature shutdowns. With a slim 40mm width, it maximizes cabinet space, while its 90.5% high efficiency ensures minimal heat generation, facilitating reliable operation through simple natural air convection.
In addition to its physical robustness, the SDR-120-24 includes active Power Factor Correction (PFC), optimizing power quality and meeting strict industrial harmonics standards. For seamless integration into automated systems, it features a built-in DC OK relay contact, providing a hardware-based signal to monitor the health of the output voltage remotely. The power supply is fully fortified with protections against short circuits, overloads, over-voltage, and excessive temperatures, ensuring maximum system uptime. Backed by international safety certifications and a 100% full load burn-in test, this unit provides a dependable and long-lasting energy solution for complex factory automation and process control systems.
