One of the key advantages of this model is the Peak Load function, which allows for a momentary delivery of up to 150% of the rated power (180W) for up to 3 seconds. This is invaluable when powering devices with high inrush current, such as motors or large camera systems. The product stands out with a very high efficiency of 89%, which minimizes energy losses and reduces heat buildup inside control cabinets. The device has a built-in DC OK signal relay, allowing for remote monitoring of voltage correctness.
The SDR-120-12 power supply has a durable metal housing and is adapted to operate in harsh environmental conditions in a wide temperature range from -25°C to 70°C. A complete set of protections: short-circuit, overload, overvoltage, and thermal, guarantees the highest level of safety for connected receivers. The MEAN WELL brand is a global leader, ensuring long and trouble-free operation in CCTV monitoring, access control, and smart building systems.
