Bel Power CP131-AG Industrial DC-DC Converter

Bel Power Solutions CP131-AG Open-Frame Linear AC-DC power supply delivers 81 watts of three‑output power from a 100–264 VAC input, producing +5 V at up to 8 A, +12 V at up to 1.7 A, and a -12 V rail at up to 1.7 A. This chassis‑mount module measures 11.00 inches in length, 4.87 inches in width, and 2.75 inches in height, designed for off‑board conversion in industrial equipment. It provides input‑to‑output isolation up to 3 kV and operates from 0 to 50 °C ambient, making it suitable for general industrial environments and test benches. Efficiency sits in the mid‑50s range for a linear supply, reflecting straightforward regulation without switching losses, while the combined outputs deliver about 81 W of power to support logic circuitry, sensors, and peripheral electronics. The CP131‑AG is part of Bel Power Solutions’ CP131 family and is intended for applications such as industrial automation, instrumentation, and equipment requiring a +5 V, +12 V, and -12 V rail from a single AC source. Its open‑frame design and chassis‑mount form factor simplify installation into equipment enclosures with proper clearance and safety margins.
