Product Description
Recom RAC04-12DC/277-E switching power supply is a high-performance, compact module designed to convert AC input voltage in the range of 80 to 264V AC into a stable 12V DC output with a power rating of 4W. Its surface mount form factor and compact dimensions of 36.7mm length, 27.2mm width, and 17.1mm depth make it ideal for PCB mounting where space is limited.
Engineered to operate reliably in harsh environments, the device supports a broad temperature range from -40°C to +80°C. Featuring 78% efficiency, it reduces energy wastage and heat generation during operation. The encapsulated housing reduces electromagnetic interference thereby improving overall system stability.
With an output current capacity of 166mA and a hold-up time of 15ms, this power supply ensures rapid energy changes and steady power delivery. Safety is guaranteed with an automatic recovery function from short circuits and a UL 94 V-0 rated enclosure that stops burning within 10 seconds under fire conditions.
Compact PCB mount package with 3.75kVAC isolation. Wide universal input voltage of 80-305VAC suits global applications. Low no-load power consumption at 50mW increases energy efficiency. Compliance with multiple safety and EMC standards including EN 61000 and UL 60950-1.
Applications include industrial automation, process control, and power supply services.
The module's design suits industrial, automation, and control environments requiring small, reliable, efficient switching power sources. It is especially useful in setups requiring compact dimensions and robust electrical performance.
