TDK has announced the addition of a 960 W rated model to its DRF series of AC-DC DIN rail mount power supplies. The high 95% efficiency produces less internal waste heat enabling electrolytic capacitors to run cooler, providing a calculated life of in excess of eleven years with a 75% load at 230Vac input. The unit can supply a peak load of 1440W (24V 60A) for up to 4 seconds to power capacitive and inductive loads. Applications include industrial process control, factory automation, and test and measurement equipment.The power supply has a 24 V output, adjustable from 24 V to 28 V, using either the front panel mounted trim potentiometer or an external 5 to 6V source. The input range is 180 to 264 VAC, withstanding surges of up to 300 VAC for 5 seconds. The operating ambient temperature is -25°C to +70oC, -40°C cold start, derating linearly above 50°C to 75% load at 70°C. The DRF series warranty is five years.
The DRF960-24-1 is 123.4 mm tall, 139 mm deep and has a narrow 110 mm width saving both space on the rail and in the cabinet. Remote on/off and a 30 V 1 A rated DC OK relay contact are provided as standard. When in standby mode using the remote on/off function, the power consumption is less than 1 W. Up to five units can be connected in parallel using the droop mode current share, for systems requiring additional power.
Input to output isolation is 3,000 VAC, input to ground 1500 VAC and output to ground 500 VAC. The DRF960 is certified to the safety standards of IEC/UL/CSA/EN 60950-1, UL508 and is CE marked in accordance to the Low Voltage, EMC and RoHS Directives. The unit is compliant to EN 55032-B (radiated and conducted emissions), EN 61000-3-2 harmonics and IEC 61000-4 immunity standards.

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.
