AC-DC

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 ...

Recom has created a 15W ac-dc power supply range that meet a wide range of international specifications including those for medical use. RACM15E-K supplies come in 80 x 23.8 x 22mm open-frame form with Molex connectors (photo below), or in a 83 x 26.4 x 29.5mm IP20 enclosure with push-in terminals and a DIN rail clip (right) – they are ...

Recom has announced a series of 140W single-output ac-dc mains power supplies that can handle 210W for ten seconds. The RACM140E-K series offers a choice of 12, 15, 24, 36 (136.8W rated) or 48Vdc depending on model. The input range is 80-264Vac and they measure 147 x 81.5mm – either 38mm tall for the open frame versions or 40mm enclosed ...

Recom has launched a series of DIN-rail ac-dc power supplies with 90 to 264Vac inputs and 120W, 240W or 480W outputs – and it has some new mini buck dc-dc module evaluation boards. Efficiency of the ac-dc DIN modules is up to 93.5%. All measure 123.4mm deep by 123.6mm high, and width is 30mm, 40mm or 56mm respectivley. The models are: ...
