The CUI Inc. VOF-225-36 is an AC-DC power supply designed for ITE (Commercial) applications. This open frame converter offers a 36VDC output with a maximum continuous power of 135W under convection cooling, and up to 225W with forced air.
Key electrical specifications include a wide universal input voltage range of 90-277 Vac and a frequency range of 47-63 Hz. It boasts high efficiency up to 90% and features power factor correction (PFC) with values of 0.98 at 115 Vac and 0.95 at 230 Vac. The unit includes over-voltage, over-current, and short-circuit protections.
Mechanically, the VOF-225-36 is designed with an industry-standard 3" x 5" footprint, measuring 127.0mm x 76.2mm x 35.0mm. It is suitable for chassis mounting. The operating temperature range is -20°C to 70°C with derating. Safety approvals include UL, CSA, and TUV, among others.
The nominal output voltage is 36 Vdc. Under convection cooling, the maximum output current is 3.75 A (135W). With forced air cooling (34.2 CFM), the maximum output current is 6.25 A (225W).
The universal input voltage range is 90-277 Vac.
The operating temperature range is -20°C to 70°C with derating.
It includes over voltage protection (38.5 Vdc), over current protection (110% hiccup, auto recovery), and short circuit protection (latch mode).
Typical efficiency is 90% at full load with 230 Vac input, and 88% at full load with 115 Vac input.
The dimensions are 127.0 mm (length) x 76.2 mm (width) x 35.0 mm (height).
It is approved by CB Scheme, CSA, EN, FCC, IEC, SIQ, TUV, and UL.
