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 ...

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. ...

Over the last decades, Mean Well has become one of the most recognisable global providers of power supply modules and converters. However, its product range also includes a broad selection of other solutions, such as KNX equipment for building automation systems. The assortment described below includes modules compatible with the KNX system, i.e. a standard applied in home and industrial ...

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. ...

The MX-Q Series 2 is the updated version of the MX series DC power supply by Aim-TTi. The quad-channel power supply has a larger colour panel, with colour-coded outputs. It also includes a TripLink feature, which allows the user to define assigned outputs for over-voltage protection and over-current protection. Aim-TTi says it has also enhanced power sharing between outputs. The ...

Vox Power has announced a set of conduction-cooled 300W dc-dc converters, for railway and other rugged environment use. Measuring 188.6 x 116 x 25.4, the 33.6 to 160V input range is intended to cover 48, 72, 96 and 110 V railway batteries. Dips to 28.8V can be ridden through covered for 100ms, complete drop-outs for 10ms, and 168V peaks for 1s. ...

TDK is aiming at motor testing with the introduction of a power sinking option to 1.7 and 3.4kW models of its Genesys+ 1U-high rack-mount dc power supplies – it is only available for 0-20, 0-30, 0-40, 0-60 or 0-100V output versions. Mounted internally, the sink module (photo below) can absorb 100W continuously and 300W of peak, and fall time can ...
