The new VOF series of economical, openframe AC/DC power supplies are available in 30W, 50W, 70W, and 85W versions, and deliver higher efficiency, improved no-load performance, and 5W extra power within the same footprint when compared to the previous generation.

Reaching efficiency of up to 90% and with no-load power consumption as low as 0.18W, the VOF-30, VOF-50, and VOF-70 models are rated for operation at 100% load from -20°C to +50°C. The VOF-85 operates at 100% load from -20°C to +40°C.

The power supplies are compact open-frame units measuring just 101.6 x 50.75 x 33.6mm. The VOF-30 models are even smaller, at 90 x 50.8 x 21.1mm. With a universal AC input voltage range of 90V to 277V, at 47Hz to 63Hz, all models offer global compatibility for OEM manufacturers. DC output voltage options include 5V, 12V, 15V, 18V, 24V, 28V and 48V depending on the series. All models include output voltage adjustability of ±5% via an on-board potentiometer.

International approvals include UL/cUL and TUV 60950-1 safety certifications, CE mark, and EN 55022 Class B and FCC Class B EMI standards. Over-voltage, overcurrent and output short circuit protection are built-in, and all models feature high primary to secondary isolation of 3kV AC.
