Product information

Description

The Black Box SDR-120-48 is a 120W power supply unit in a blue stainless steel enclosure. It provides a regulated 48 VDC output and accepts a wide AC input voltage range of 85–264 VAC at 47–63 Hz. The compact unit (40 mm × 113 mm × 125 mm) includes finger-safe terminals, an LED that indicates DC output presence, and is certified to cUL and CE safety standards.

Advantages

The unit supports a wide universal AC input and can also accept 120–370 VDC input (not certified for DC), operates over an extended temperature range of -4 to +158 °F, and offers built-in protection against short circuits, overload and over-voltage. Its stainless steel housing provides mechanical durability and a compact footprint for space-constrained installations.

How to use

Mount the SDR-120-48 in a suitable enclosure or on a DIN rail as allowed by your installation guidelines, connect the AC input to the 85–264 VAC supply (observe correct wiring and grounding), and connect the 48 VDC load to the output terminals. Verify the LED indicator for DC presence. Follow local electrical codes and the device’s installation instructions when making connections.
