MEAN WELL IRM-20-24 20W 24V 0,9A gegoten PCB-montagevoeding, 85-264V AC-ingang, zwart

Delivering 20 watts of continuous power from a compact encapsulated module, the MEAN WELL IRM-20-24 converts 85–264 V AC mains input into a tightly regulated 24 V DC output at 0.9 A. Its 88% efficiency and free-air convection cooling keep thermal stress low, while built-in short-circuit, overload, and over-voltage protection ensure dependable operation in industrial and ITE environments.

Overview

The IRM-20-24 is a PCB-mount AC/DC power supply designed for space-constrained applications that demand reliable, low-noise DC power. Encapsulated in a flame-retardant black housing, it withstands harsh conditions and provides galvanic isolation of 3000 V AC between input and output. Compliance with UL 60950-1, EN 60950-1, and IEC 60950-1 safety standards makes it suitable for a wide range of information technology equipment and industrial controls.
