5 and 20W OVC III PSUs accept 85 to 528Vac for industry
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 ...
15W ac-dc PSUs are industrial and medical specified
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 ...
140W ac-dc PSU handles 210W surges for 10s
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 ...
Universal input ac-dc DIN rail PSUs up to 480W
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: ...
GaN power IC aimed at 65W USB PD adapters
A French-Taiwanese collaboration has produced a primary-side IC for 65W ac-dc USB PD adapters. The companies are GaN specialist Wise-integration and mixed-signal IC maker Leadtrend Technology. Together that have created LD966L, a 650V system-in-package multi-mode PWM fly-back converter with Leadtrend’s silicon controller die and an enhancement-mode GaN transistor die from Wise. It comes in an 8x8mm QFN package and its ...
3.5kW three-phase supplies deliver 48 or 65V
Cosel has introduced a 3.5kW ac-dc 1U rack-mount power supply that will run from three phases between 180 to 528Vac. Two versions are available giving a choice of 48 or 65Vdc output, each trimmable +15% to -50% (24 to 55.2V, or 32.5 to 74.75V). Called HFA3500TF, the enclosed PSUs have three-wire inputs and will run from delta or star power networks. ...
50kW grid and load emulator tests wind turbines and EV chargers
Intepro Systems is stocking a 50kW regenerative ac-dc electronic load and grid simulator from Cinergia. Called ‘GE&EL+ vAC/DC SiC’, Intepro describes it as: “The whole Cinergia catalogue in a single unit. [It] is both an ac and dc grid emulator, and can also works as a load [and] is ideal for testing solar panels, wind turbines, hardware-in-the-loop power, smart grids, ...
1kW harsh environment PSU sealed to IP65
Powerbox is aiming at ground-based defense applications and harsh industrial environments with a 1,000W IP65 ruggedised ac-dc power supply series. ECD1000A comes in a metal enclosure with baseplate conduction cooling and can be used with the plate from -40 to +75°C, derated in some situations. Operation is from 85 to 305Vac (100 to 277Vac nominal) and output is 28Vdc 36A. ...
Power Integrations takes on post regulators with InnoMux IC
At APEC 2024, Power Integrations‘ chairman and CEO, Balu Balakrishnan, “declared war on DC-DC post regulators”, as the company introduced the GaN-based InnoMux-2 switcher IC family. The company said that the new ICs are an example of its value and energy focus because it combines AC-DC and DC-DC stages into a single power converter, resulting in a reduction in power ...
