V-Infinity's VPF/VPM-S800-XXR series 800W switching power supplies are suited to industrial and networking applications. The supplies, available in U-frame (VPF designation, 7.99-by-4.33-by-2.56 inches) and metal-enclosed (VPM designation, 9.17-by-4.25-by-2.5 inches) versions, deliver 12Vdc to 48Vdc in five models from a universal AC input.

Features include a load regulation of ±1 percent, ripple and noise of 1 percent, output adjustable by ±5 percent, transient response of 2.5ms for a 50 percent load change and return to 1 percent of output voltage, and efficiency of at least 80 percent. The units deliver full output power over 0 to 50°C, and require 30cfm of airflow for cooling. Power de-rates linearly from 50°C to 70°C to 50 percent of full output.

These supplies have an internal EMI filter, remote on/off, remote sense, and provide over-voltage, over- current, over-temperature, and short-circuit protection. Optional OR-ing diodes can be implemented for current sharing applications. Safety approvals include UL/cUL/TUV/CE/CB.

OEM pricing starts at $165 per unit. Availability is 6 to 8 weeks in production volumes.
