V-Infinity’s family of convection-cooled 120 watt 1U height switching power supplies are now RoHS compliant. The 3”x5” units are designed for a range of information technology, datacom, wireless, and industrial applications. Exact dimensions of the VSUU-120 u-frame series measure 3.2 x 5 x 1.54 inches, while the open PCB VSBU-120 series measures 3 x 5 x 1.28 inches. All models feature PFC.

Voltage outputs range from 3.0-50.0 Vdc on 11 different single-output models. In addition, V-Infinity also offers 7 dual output and 18 triple output models. The power supply produces full output power from 0 to 50° C. Power de-rates linearly from 50 to 70° C, at which point the VSUU still produces 50% output at 70° C. Features include an internal EMI filter, over voltage, over current, and short circuit protections.

Safety approvals include UL/cUL/TUV/CE/CB. OEM pricing starts at $43 per unit.
