CUI’s Power Group has announced a new line of compact, chassis mount AC-DC power supplies housed in an enclosed metal case. The VGS-B series offers power ratings from 35 W to 350 W with low 30 mm profiles and compact packages as small as 99 mm x 82 mm x 30 mm (3.89″ x 3.22″ x 1.18″). Delivering no-load power consumption as low as 0.3 W and an operating temperature range of -20°C to +70°C, these rugged, metal enclosed power modules are well suited for reducing standby power usage and optimizing available space within commercial and industrial applications.
CUI’s VGS-B power supplies carry single output voltages of 12, 24, 30 and 48 VDC, depending on the series, and an adjustable output trim. While most of the series are convection cooled, the VGS-250B and VGS-350B series both feature built-in cooling with a temperature-controlled fan. All models further feature a screw terminal interface, along with over current, over voltage and over temperature protections.
Safety approvals for the VGS-B series include UL and EN 60950-1 as well as EN 55032 for conducted and radiated emissions. The VGS-B series are available immediately with prices starting at $14.07 per unit (100s) through distribution.

RECOM has expanded its low power AC/DC portfolio with encapsulated 5 W power supplies, which operate up to +90°C. They accept input voltage lines of up to 305 VAC and offer peak power capability up to 6 W. These modules are well suited for Industry 4.0, IoT and smart household applications requiring features that go beyond the industry standard.
With its RAC05-K/277 series, RECOM introduces 5 W AC/DC converters that support peak power needs and are specially designed for extended input lines and reliable operation at extreme temperatures from -40°C up +90°C. The RAC05-K/277 series are built to operate from extended input lines with mains voltages from 85 VAC up to 305 VAC, are EMC compliant to EN55022 class “B” with a minimum 6 dB margin on both radiated and conducted readings without the need for external components.
At a 1” x 1.25” footprint, these new PCB-mount or wired modules feature fully protected outputs and international safety certifications for industrial, household and ITE for worldwide use. The RAC05-K/277 series is an addition to RECOM’s ultra-compact RAC05-K converters with a 1” x 1” footprint, as well as the recently released RAC05-K/480, an AC/DC module dedicated for phase-to-phase operation up to 528VAC and exclusive only to RECOM. Wired versions of the RAC05-K/277 series are due to be released in October of 2018. Samples of the pin-versions and OEM pricing are available from all authorized distributors or directly from RECOM.

XP Power has launched its low-cost VCE03 and VCE10, 3 W and 10 W series of board-mounted AC-DC power supplies with extended universal input range from 85 VAC to 305 VAC, covering all nominal AC inputs from 100 VAC to 277 VAC 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. Their small size, high efficiency and low no load input power consumption makes them well suited for IoT applications.The 3 W parts are available in an ultra-compact encapsulated or open-frame SIP package for maximum flexibility and potential cost and space savings. The compact 10 W parts are offered as encapsulated or open-frame DIP’s. Their high-active efficiency and low no-load input power of less than 0.3 W 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 V, 5 V, 9 V, 12 V, 15 V, 24 V and 48 V with over-load, over-voltage and short circuit protection included.
All models are class II, earth-free construction and have 3000 VAC 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 305 VAC allows use of the parts in 277 VAC 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 & measurement equipment.
The VCE03 & 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.

CUI’s Power Group today has announced the addition of two models to its PBO family of ultra-compact AC-DC power supplies. Outputting 1 W of continuous power, the open frame PBO-1 and PBO-1-B series are housed in vertical and right-angle SIP packages, respectively. The vertical PBO-1 series measures as small as 35 mm x 11 mm x 18 mm (1.38″ x 0.43″ x 0.71″), while the low profile, right-angle PBO-1-B series measures as small as 35 mm x 18 mm x 11 mm (1.38″ x 0.71″ x 0.43″), making them well-suited for industrial systems, automation equipment, security, telecommunications and smart home devices where limited board real-estate is a factor.
These high density power supplies feature wide input voltage ranges from 85 to 305 Vac or 70 VDC to 430 VDC for high voltage DC-DC applications. The PBO-1 and PBO-1-B come available with single output voltages of 5 V, 9 V, 12 V, 15 V, and 24 V DC and offer 3,000 VAC input to output isolation. Both series also offer a wide operating temperature range from -40°C to +85°C at full load as well as over current and continuous short circuit protections with auto recovery.
All models further feature class II construction, carry UL 60950-1 safety approvals, and bear the CE safety mark. The PBO-1 and PBO-1-B series are available immediately with prices starting at $4.74 per unit at 100 pieces through distribution.
