A high-tech factory specializing in flow meters
The company's instrument science and technology park covers an area of 100,000 square meters
PFE500 SA-28, AC-DC full brick power module, rated 504W, 28V output, with PFC power factor correction, commonly used power module for industrial / communication equipment

I. Appearance and mechanical structure
Packaging: standard full brick module, metal base plate (thermal conductivity and heat dissipation, must be equipped with a heat sink), black plastic casing, 4 corners with installation and fixing holes
Dimensions: 116.8 × 61 × 12.7 mm; The weight is about 200g.
Interface: AC input pin on one side, DC output pin on the other side, through-hole pin welded on the PCB board; Top surface sticker with parameter nameplate label
Heat dissipation method: base plate conduction heat dissipation, no built-in fan, the base plate must be attached to the heat sink, cannot naturally cool TDK Produc...
