Power Supply Unit (PSU)

Recom has created a wide input range 1.5 x 2inch 15W ac-dc converter that operates over part that operates over 18 – 264Vac, or 18 – 375Vdc. All parts have a 40 x 52.5mm footprint and stand 25.5mm tall. PCB versions (RAC15-xxSK/WI) have through-hole pins underneath, while the flying lead version (add /W suffix) have four 100mm wires protruding from the ...

For those wanting a little more on the advantages of GaN power transistors in small mains power supplies, ElectrArc240 has created an excellent YouTube video. ElectrArc240 has clearly knows what he talking about and has spent a long time testing different aspects of two similar power supplies to succinctly demonstrate their differences: one with a GaN hemt main switch and ...

Cinon has created a range of 550W ac-dc single output power supplies measuring ~130 x 84 x 25.4mm. The power supplies do not have an internal fan, and 550W is only achievable with both baseplate and blown air cooling above 21.9cfm, with derating starting at 50°C ambient, and the maximum allowable load dropping to 350W at 80°C. With un-blown ambient ...

XP Power’s CCR range of ac-dc power supplies is rated for BF (body floating) medical use from 110W to 420W. With a 25.4mm profile, there are three difference sizes, where each device has three different power ratings depending on how it is cooled: by forced air, by base-plate conduction or by natural convection: CCR200 79x58mm, 200W fan, 170W conduction, 110W ...

Following its acquisition or Leco, Recom has launched a series of DIN rail power supplies for three-phase and dc input busses. Two-phase ac operation is also possible. Called the RACPRO1 range, it includes five parts: 240W (24Vout), 480W (24 or 48Vout) or 960W (24 or 48Vout), which are 43mm, 52mm or 80mm wide respectively. Update: The company introduced matching electronic ...

To handle inputs from 43 to 160Vdc, and outputs of 50, 100 or 150W, TDK has added quarter brick dc-dc converters to its CN-B110 series, which previously only had 200 and 300W half-brick models. “The converters are compatible with 72Vdc or 110Vdc nominal railway systems for applications such as rail rolling stock and trackside equipment,” according to the company. Output choice ...

For the gate drivers of high-power IGBTs, mosfets, SiC mosfets and GaN hemts, Infineon has introduced an isolated power supply IC that can generate asymmetric output voltage rails. Each member of the 2EP1xxR family, as it will be known, has a full bridge of mosfets at its output for driving both ends of a transformer primary, whose secondary can be ...

Murata has announced a 600W open-frame ac-dc power supply for medical and industrial use. PQC600 is less than 1U in height, although does need room for forced cooling if it is to reach full power. Certification is to IEC 60601-1 edition 3 medical safety, which includes 2 MOPP (means of patient protection) from primary to secondary, 1 MOPP from the ...

Renesas is aiming at Intel’s Core Ultra 200V series of processors with a pair of power ICs. RAA225019 is a six-phase buck converter, designed to work with IMVP9.2 Lunar Lake processors. Integrated within is the switching controller, power mosfets and current-sensing. “Six phases can be distributed across three outputs – two SVID rails and one auxiliary rail,” said Renesas. “SVID1 ...

Vox Power Ltd has announce the EIRE300 series of 300W open-frame ac-dc power supplies for medical and IT equipment use, that measure 4 x 2 x 1inch. 300W is with forced air and only 200W (115Vac) is available continuously if only convection cooling is available – with ambient temperature caveats. Up to 375W can be delivered for 1s. Different models ...
