IRM-05-5 (PM93) Overview
The DAPPRA IRM-05-5 (internal code PM93) is a 5W PCB-mount AC-DC encapsulated power module delivering 5V DC at 1.0A. It is the smallest model in the IRM Series PCB-mount platform, with a compact 45.7 × 25.4 × 21.5 mm footprint that fits into very tight PCB assemblies and low-power embedded designs.
The module accepts a universal AC input range of 85–264VAC (or 120–370VDC) and provides a regulated 5V output at up to 1.0A with approximately 71% typical efficiency. It is fully encapsulated and uses free air convection cooling, making it suitable for providing a 5V logic rail directly on a control board, interface board or small electronic device without a separate external power supply.
Short circuit, overload and over voltage protection are built in. The IRM-05-5 is a Class II construction module and does not require an FG/PE connection for basic operation, simplifying PCB layout and wiring in low-power applications.
