Industrial Power Supply with Dual DC Outputs

Power Supplies - 130VDC to 48~12V Dual Output DC/DC Power Supply
130VDC to 48~12V Dual Output DC/DC Power Supply

The RLH DC/DC 48~12VDC Dual Output DIN rail mount power supply is a compact power supply designed to convert 130VDC power (72~144VDC) to regulated 48VDC and 12VDC output to power a wide range of industrial equipment.

Each internal regulated power supply section is separate and independent of the other power section, allowing for maximum efficiency and operation.

The power supply may be DIN rail or wall-mounted, and includes a power indicator for each output section so that performance and operation may be quickly assessed. It has low output ripple along with short circuit, overvoltage and overload protection, fanless convection cooled design, and extended operating temperature range with high efficiency.

This rugged power supply features a tough aluminum alloy frame with powder coated galvanized steel housing for superior corrosion resistance.
