The XP Power MFA420PS48-STF is a high-power density AC/DC converter designed for industrial applications. It delivers up to 420W of power with a 48V main output, complemented by a 5V standby output and a 12V fan output. The unit operates across a universal AC input range of 85-264 VAC and offers an efficiency of up to 88% at full load.
Designed for robust performance, the MFA420PS48-STF operates within a temperature range of -10°C to 70°C with derating. Its features include active current sharing, remote on/off control, and AC/DC OK signals, making it suitable for demanding ITE (Commercial) applications. The converter is built with a chassis mount, enclosed type for easy integration into systems.
Key electrical specifications include a maximum output current of 8.8A for the main output, a startup delay of 12 seconds, and a hold-up time of 16-20ms. It also incorporates overvoltage, overload, and short circuit protection for enhanced reliability. The power density is rated at 11.1 W/in³.
