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 ...

TDK-Lambda has announced a series of rugged conduction-cooled dc-dc buck converters rated up to 750W. They come in a five-sided conduction cooled aluminium housing that measures 38.1 x 49.5 (39.4) x 13mm including (ignoring) mounting tabs. None are isolated and all have a single regulated output, remote on-off, remote sense and output trim – through a standard 1/16th brick through-hole ...

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 ...

Puls has announced three 240 or 480W DIN rail ac-dc dc-dc power supplies with an integrated EtherCAT interface for configuration, operation monitoring and remote control. Data over the bus includes voltage and current characteristics on the input and output sides, and direct connection to an EtherCAT controller is possible without intervening gateways. “Real-time data transmission makes possible the monitoring, logging ...

Alpha and Omega Semiconductor is aiming at Meteor Lake and Arrow Lake notebooks with a multi-phase dc-dc converter controller that meets Intel IMVP 8, 9, 9.1, and 9.2 specifications. AOZ71137QI is a three rail seven-phase controller for CPUs that has: up to four phases for the core voltage (‘IA domain’), up to two phases for graphics (‘GT domain’) and one ...

Transistor maker Cambridge GaN Devices has signed a memorandum of understanding with Taiwan’s Industrial Technology Research Institute to develop USB-PD adaptors as well as to share international market information, visit to potential customers and promote the PSUs. The agreement covers 140 – 240W, >30W/in3, ac-dc power adapters for e-mobility, power tools, notebooks and phones (prototype GaN-based USB PD adapter right) ...

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. ...

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. ...

Advanced Energy Industries is showing its NP08 4kW ac-dc power supply at APEC in Long Beach this week. The first member of its NeoPower (NP) family of configurable multi-output supplies, it has eight output slots for configuration and 18W/inch3 claimed density for ~283 x 203 x 64mm chassis. Input is single-phase 90 – 132Vac and 180 – 264Vac. “NP08 also ...

Cosel has announced a series of ac-dc power supplies with enhanced reliability for industrial applications. Called the PDA series, the PSUs are form, fit and function backwards compatible with the company’s 20 year old PBA series, with fewer internal components explaining part of the reliability increase. With more to follow, the initial versions are: PDA15F (15W 31 x 78 x 85mm), ...
