Economical Open Frame Ac-Dc Power
Supplies Deliver up to 280 W in a Compact
Package
CUI Inc announced the expansion of its VOF open frame ac-
dc power supply family with the introduction of 185, 225
and 280 W models. The VOF 185, VOF 225 and VOF
280 series are higher-power additions to CUI’s latest-
generationopen frameac-dc power portfolio ranging from
6 to 150 W. Designed to offer a combination of economy
and performance in a compact, industry standard 3” x
5” footprint, the single output power supplies deliver
efficiencies up to 91% and no-load power consumption
as low as 0.5 W at 230 Vac for energy-conscious ITE,
industrial and consumer electronics applications.
The three new VOF series feature a wide universal input
voltage range of 90 to 277 Vac and offer output voltage
options of 12, 15, 24, 36 and 48 Vdc. All models provide
an operating temperature range at full load from -20 up
to +50°C with forced air cooling, derating to 50% load
at +70°C. The new power supply family also carries
UL/cUL and TUV 60950-1 safety certifications while
meeting EN 55022 Class B and FCC Class B limits for
radiated emissions.
The series has an MTBF of 250,000 hours minimum at
full load at 25°C ambient, calculated per MIL-HDBK-
217F. Protections for over voltage, over current and
short circuit are included as well as 0.98 typical power
factor with active PFC.
The VOF-185, VOF-225 and VOF-280 are available
immediately with prices starting at $69 per unit at 100
pieces through distribution. Please contact CUI for OEM
pricing.
Visit CUI’s booth (Power Hall A2, Booth 613) at
electronica 2016 where the company will be showcasing
the three new VOF series and the rest of their power
portfolio ranging from 1 W to 12,000 W. electronica is
the world’s leading trade fair for electronic components,
systems and applications, and will be held at the Messe
München in Munich, Germany from November 8-11,
2016.
