The RLH DC/DC converter is a compact power supply designed to convert a DC Input voltage to a regulated and isolated DC output voltage. Able to power a wide range of industrial equipment this power supply offers a wide variety of conversion options to accommodate standard voltages found in substations, Telco, & automation and control environments.

This rugged power supply features a tough aluminum alloy frame with powder coated galvanized steel housing for superior corrosion resistance. The DIN clip allows for easy mounting anywhere DIN rail can be placed.

Each model supports a wide input voltage range and allows for adjusting the output voltage to +/-10 % of the rated output voltage. The converter has a bi-color LED indicator and a relay output to indicate power status and alarm conditions.
