V-Infinity's new U-frame switching power supply

Citing its economical design, V-Infinity's new U-frame switching power supply series, the VPU-S200, delivers up to 200W for wireless, datacom and industrial applications.

The universal-input units (85- to 264Vac or 120- to 340Vdc), in eight single-output models, deliver from 3.3- to 48Vdc. Operating efficiency is as high as 81 percent. The units are rated for operation at 100 percent load from 0 to 50C ambient with 18CFM of forced air cooling.

Additional features include RoHS compliance, active power-factor-correction, remote on/off and short-circuit, over-current and over-voltage protection. These units meet CISPR/FCC class B standards for conductive EMI. Approvals include UL/cUL/TUV/CE/CB.

OEM pricing for these units, which measures 6.81-by-3.82-by-1.5 inches, starts at $44.75 per unit. Availability is five to seven weeks in production quantities.
