Overview
IRM-10-12 (PS24) Overview
The DAPPRA IRM-10-12 (internal code PS24) is a 10W PCB-mount AC-DC encapsulated power module delivering 12V DC at 0.85A. It sits between the 5W IRM-05-5 and the 15W/20W models, sharing the compact 45.7 × 25.4 × 21.5 mm footprint of the IRM-05 while providing more output power for 12V loads.
The module accepts a universal AC input range of 85–264VAC (or 120–370VDC) and delivers up to 0.85A at 12V with approximately 82% typical efficiency. Like the other IRM Series modules, it is fully encapsulated and uses free air convection cooling, making it suitable for PCB-level power conversion in compact control boards, instrumentation and low-to-medium power embedded designs.
The IRM-10-12 is commonly used to provide a 12V rail for relays, sensors and interface circuits on a control board where a larger power supply is not practical. Short circuit, overload and over voltage protection are built in. Class II construction eliminates the need for an FG/PE connection in most configurations.
