The RAC20NE-24SK/277 is a 20W encapsulated AC/DC power supply module designed for constant voltage operation. It accepts a wide input voltage range from 85VAC to 305VAC and provides a regulated 24VDC output with a nominal current of 833mA. This module features a typical efficiency of 87%, an OVC III rating for operation up to 5000m altitude, and a wide operating temperature range of -40°C to +85°C. Integrated protections include short circuit, over-current, and over-voltage, all with hiccup mode auto-recovery. Its compact size, high immunity, and low standby power consumption make it suitable for space-critical industrial, energy management, and automation applications.
