PFE500SA‑28 (TDK‑Lambda) Full‑Brick Package AC‑DC Power Module

This is a full‑brick package AC‑DC power module (on‑board power supply). It directly converts mains AC into DC power supply. Rated at 504 W, this is an industrial high‑power TDK power module featuring conductive cooling and metal base‑plate mounting with no fan required.

Key Specifications

‑ Input: 85‑265 VAC (universal worldwide mains input)

‑ Output: 28 V DC, max. 18 A, 504 W

‑ Efficiency: 89% typical

‑ Package: Standard full‑brick form factor, base‑plate conductive cooling

‑ Protections: Over‑current (auto‑recovery), over‑voltage, over‑temperature protection

Features

AC‑to‑DC conversion: Converts 110 V / 220 V AC mains to stable high‑current 28 V DC for downstream equipment.

Built‑in PFC (Power Factor Correction), compliant with grid harmonic standards.

Base‑plate thermal conduction cooling via external heat sink; ideal for fan‑less enclosed equipment.

Output voltage adjustable within a small range (‑20% ~ +20%).

Comprehensive protection: over‑current, over‑voltage and over‑temperature fault protection to prevent damage to downstream loads.

Applications

‑ Industrial equipment: Industrial controllers, test & measurement instruments, laser equipment

‑ Telecom equipment: Communication base stations, switches, networking hardware

‑ Medical devices (compliant with relevant safety standards)

‑ Outdoor equipment, military‑grade systems, high‑power embedded systems

‑ High‑power power‑supply scenarios for enclosed enclosures where fans cannot be installed
