AZO Digital 24 VDC / 13.8 VDC Power Converter PE-40 450W IP21

The AZO Digital 24 VDC / 13.8 VDC Power Converter PE-40 450W IP21 is a high-efficiency step-down (buck) converter designed to convert a nominal 24 VDC input to a stable 13.8 VDC output, delivering up to 450W of continuous power. Ideal for industrial, telecommunications, and automotive applications, this converter features fan-assisted cooling, comprehensive protection, and a rugged IP21-rated enclosure.

Advantages

With over 90% efficiency, the PE-40 minimizes energy loss and heat generation. Its wide input voltage range (20-30 VDC) ensures reliable operation even with fluctuating power sources. The built-in protections (overload, short circuit, over-temperature, input reverse polarity) safeguard both the converter and connected equipment. The fan-assisted cooling allows continuous operation at full load in ambient temperatures up to 50°C.
