AZO Digital PU-250 24V 250W IP21 DC-DC Step-Up Voltage Converter 10-20VDC Input

Many industrial and mobile applications require a stable 24 VDC supply, but available power sources often provide only 10-20 VDC. The AZO Digital PU-250 solves this mismatch by stepping up lower DC voltages to a regulated 24 VDC output, delivering up to 250 W of continuous power. Its robust aluminum housing and IP21 rating make it suitable for protected indoor environments where reliable voltage conversion is critical.

Who is it for

This converter is ideal for system integrators, automation engineers, and technicians working with 12 V or 18 V battery systems, solar installations, or vehicle electronics that need a clean 24 V rail. It is also suitable for powering 24 V industrial sensors, controllers, and actuators from lower-voltage DC buses.
