RLH-D-DCDC-4812H-1 Dual Output Power Supply
RLH DC/DC Dual Output Power Supply DIN/Wall Mount 130VDC INPUT TO REGULATED 48VDC & 12VDC OUTPUT
Overview The RLH 130V Dual Output DC/DC DIN rail mount power supply is a compact power supply designed to convert 130VDC power (43~160VDC) 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, over-voltage and overload protection, fan-less 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.
Standard Features
130VDC input with 48VDC & 12VDC output terminals
Short circuit, overload, over voltage and over temperature protection
Cooling by free air convection
May be installed on 35mm DIN rail
Individual LED power indicators for each output
Convenient screw down terminals accept up to 8AWG wiring
