Bel Fuse MAP55-4000 Power Supply

Bel Power Solutions MAP55-4000 is a 65 W, four-output AC-DC power supply designed for IT and embedded equipment, delivering +5 V, +12 V, -5 V, and -12 V rails from a 90–264 VAC input. This fan‑cooled, chassis‑mount unit (U‑Chassis package with a Molex header) is RoHS compliant and is intended for Information Technology Equipment markets and related industrial applications. Continuous output ratings are +5 V up to 6 A (with a peak capability near 8 A), +12 V up to 3 A (peak up to 5 A), -5 V up to 0.5 A (peak 1 A), and -12 V up to 0.5 A (peak 1.5 A), with regulation of about 0.2% line and 2% load, and ripple around 1%. The +5 V rail is specified with an initial accuracy of 5.0–5.2 V. Note that this model has been discontinued by Bel, and Bel’s MAP55-4000G family is listed as the recommended replacement, offering a similar four‑rail output, 90–264 VAC input, and a comparable form factor for IT/industrial applications.
