The RAC04NE-12SK/277/W is a robust, IP65-rated, wired AC/DC power supply module designed for continuous operation. It delivers 4W of continuous power at a regulated 12VDC output from a universal 85-305VAC input. A key feature is its ability to provide 6W of boost power for up to 20 seconds, and it can operate at full load across a wide temperature range from -40°C to +80°C. The module offers enhanced surge immunity of 2kV (L-N) and 4kV (L-PE), meets Overvoltage Category III requirements up to 3000m, and has a low no-load power consumption of 75mW. Its encapsulated, wired construction makes it ideal for demanding industrial automation, building control, and household applications.
