XP Power is launching its low cost VCE03 and VCE10, 3W and 10W series of board-mounted AC-DC power supplies with extended universal input range from 85-305VAC, covering all nominal AC inputs from 100-277VAC in a single ultra-compact design.

Both the VCE03 and VCE10 provide a complete AC-DC solution with integrated EMC filter and hold-up capacitor, meaning there are no extra external components required, offering a genuine space-saving solution for today’s compact equipment.

The 3W parts are available in an ultra-compact encapsulated or open-frame SIP package for maximum flexibility and potential cost and space savings. The compact 10W parts are offered as encapsulated or open-frame DIP’s.

Their high active efficiency and low no-load input power of less than 0.3W make these devices suitable for a wide range of applications supporting environmental initiatives for end equipment. The series offer a wide range of outputs covering 3.3, 5, 9, 12, 15, 24 and 48V with over-load, over-voltage and short circuit protection included.

All models are class II, earth-free construction and have 3,000VAC isolation rating with world-wide safety approvals to IEC60950-1 for ITE equipment, IEC/UL/EN62368-1 for ITE and audio-visual equipment and IEC/EN60335-1 for household appliances. The parts comply with EN55032 Level B conducted and radiated emissions.

No external heatsinking is required, with convection cooling giving an operating temperature range for both series from -25°C to +70°C, with full power available up to +50°C.

The extended input range up to 305VAC allows use of the parts in 277VAC nominal systems, common in lighting applications and in industrial areas generally. The parts will find applications in lighting, automation and process control, instrumentation, set-top boxes, household devices, home automation and test and measurement equipment, while their small size, high efficiency and low no load input power consumption makes them suitable for IoT applications.

The VCE03 and VCE10 can also be implemented as auxiliary supplies in larger power conversion systems where they can maintain control circuitry powered on standby, allowing main conversion stages to be fully disabled, reducing standby and no-load losses.

“These high quality board-mount AC-DC power supplies give a fully safety and EMC-compliant, low cost solution as a power supply for small systems or auxiliary supply in larger power converters. With high MTBF and our three year warranty, they are a great ‘fit and forget’ solution.” Steve Head - Marketing Director, XP Power.
