V-Infinity Introduces New Medical Switchers That Deliver 400W in a 1U Package

July 16, 2006 by Jeff Shepard

V-Infinity LLC introduced a new family of 400W switching power supplies designed for a wide range of medical applications. Carrying full medical agency safety approvals, these low-profile units are available in u-frame or fan-cooled metal enclosed packaging. Exact dimensions of the VUFM-S400-XXR u-frame series measure 8.0x5.0x1.60 inches while the VUMM-S400-XXR metal-enclosed series measures 9.0x5.0x1.60 inches. All models feature EN61000-3-2 class D active power factor correction and have a leakage current of less than 300 µA. In addition, optional ORing diodes can be implemented for current sharing applications.

Voltage outputs range from 3.3-58.0 Vdc, adjustable by +/-5%. The units produce full output power from 0 to 50°C, requiring only 22.95 cfm of airflow for cooling. Power de-rates linearly from 50 to 70°C, at which point the units still produces 50% output at 70°C. Features include on/off control, remote sense, current monitoring, power fail detect, over voltage, over current, over temperature, and short circuit protections. OEM pricing starts at $150 per unit.
