Low-cost 60 W power supplies

28 February 2022 Power Electronics / Power Management

XP Power has released a new series of low-profile 60 W AC-DC power supplies that are intended for use in a wide variety of cost-sensitive applications including IT equipment, industrial and domestic electronics, Internet-of-Things (IoT) and robotics applications.

In order to further penetrate markets and grow sales, manufacturers in cost-sensitive application sectors are constantly seeking high-quality, easy-to-use power solutions at attractive price points and it is this need that the new VCB60 series addresses.

The modules operate from 90 to 305 V AC, making them suitable for global factory or roadside equipment running 4-wire 480 V AC 3-phase (277 V AC nominal) or 1-phase (110/230 V AC nominal) systems. With a total of eight devices in the series, regulated output voltages from 5-54 V DC are covered at power levels up to 60 W. The convection-cooled devices require no forced air, ensuring silent operation which is a common requirement in noise-sensitive audio/video (AV) applications as well as in office or domestic settings.

OVC III (overvoltage category III) approval means that VCB60 units can be used in building wiring upstream of wall sockets that require safety-approved products. The approval removes any need for additional filtering and safety approvals.

The VCB60 series carries multiple approvals, including EN55024, EN55035 and EN61000-4 for EMC immunity and EN55032, EN55014 and EN61000-3 for EMC emissions. Safety approvals include IEC60950, IEC62368 and IEC60355.

Efficiency is 90%, ensuring that waste heat is minimised. This reduces thermal management requirements and also decreases operating temperature, thereby enhancing the reliability of the overall system. Various protection mechanisms are incorporated, including short-circuit, over-voltage and overload protection. VCB60 units are able to operate over the temperature range of -10°C to +60°C and offer full power at temperatures up to +50°C.
