Finnish company Enedo Power has turned to GaN transistors to put a 1,200W ac-dc power supply into a 41 x 107 x 206mm (900cm3) volume. Called HDP1200, they run from 85 – 305Vac (de-rated to 1kW below 137Vac) and produce 24V or 48V depending on type, plus a 5V 1.5A stand-by output. Efficiency is up to 95.5%, and a fan ...
XP Power has launched a host of GaN-based plug-in ac-dc power supplies rated between 65W and 140W. The basic types are: PGW65 wall-mount 65W (0.37W/cm3 – 6.06W/in3) PGW100 wall-mount 100W (0.53W/cm3 – 8.72W/in3) PGD100 corded 100W (0.48W/cm3 – 7.93W/in3) PGD140 corded 140W (0.55W/cm3 – 9.0W/in3) They “are designed to conform to the Power Delivery protocol and are ideal for industrial ...
Rohm has released hybrid analogue-digital controlled design for a 24V 4A output mains PSU built around its ML62Q2035 16bit RISC MCU. The design, called REF67004 and implemented on the LogiCoA003-EVK-001 evaluation board, incorporates a critical conduction mode PFC (power factor correction) stage followed by an isolated quasi-resonant fly-back converter. “Analog-controlled power supplies are widely used in small to medium-power industrial ...
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 ...
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 ...
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 ...
Bourns is offering IEC-grade surge protection for ac or dc power rails with four DIN rail mount device series. 1270 series AC surge protection to IEC/EN 61643-11 Class I + Class II / T1+T2 1280 series the same, plus a thermal disconnector “that eliminates the need for up-stream over-current protection”, said Bourns. 1430 series DC surge protection to IEC/EN 61643-31 ...
XP Power has introduced a range PCB-mount PSUs that will run from 85 to 528Vac. There are 5W (EHL05) and 20W (EHL20) types, all single output, with 3.3, 5, 9, 12, 15, 24 or 48Vdc outputs depending on version. There is a choice of open-frame or encapsulated (see photo) packaging, and efficiency is typically between 82 and 88% – 3.3V ...
