AZO Digital 40-130 VDC / 13.8 VDC PS-250-12V 250W Voltage Converter Galvanic Isolation, IP21

The AZO Digital PS-250-12V is a high-performance DC-DC voltage converter designed to convert a wide input voltage range of 40-130 VDC to a stable 13.8 VDC output. With a continuous output power of 250W and a maximum output current of 18.1A, this converter is ideal for industrial and telecommunications applications requiring reliable power conversion with galvanic isolation. Its IP21-rated enclosure provides protection against solid objects larger than 12.5mm, making it suitable for indoor use in controlled environments.

Advantages

Galvanic isolation ensures safety and reduces noise interference between input and output circuits. The wide input voltage range accommodates various DC power sources, while passive cooling ensures silent operation and long-term reliability. Built-in protections against overvoltage, reverse polarity, overload, short circuit, and overtemperature safeguard both the converter and connected equipment.
