Power supplies meet highly demanding applications
Powerbox has announced the release of its new Defense Line of ruggedised power solutions for highly demanding environments. The launch includes seven series of new power supplies, comprising three DC/DC (DAA-DAB-DAC), four AC/DC (DBA-DBB-DBC-DBD) and embracing a power range from 50W up to 1,200W. In metal chassis format with a baseplate for conduction cooling, the DAx and DBx series can be used with a baseplate operating temperature range of...
SiC MOSFET driver reference design optimised for desaturation protection
A new SiC MOSFET driver reference design from Microsemi is available at Richardson RFPD supported by full design support capabilities. The MSCSICMDD/REF1 is designed to provide a reliable reference driver solution, a means of evaluating silicon carbide MOSFETs in a number of different topologies, as well as a means to assess device performance for parametric test purposes.
ICE Block is suitable for data centre operators
CUI announced that it has successfully deployed initial test units of its Intelligent Control of Energy ("ICE") Block technology. Deployment of the units highlight ICE Block's peak shaving capabilities and includes a new ICE Switch product that further unlocks power capacity for the customer. CUI and VPS announced a partnership in 2016 for VPS' ICE solution that brings the benefits of elastic power to data centers and sets a new standard for effi...
480W power supply designed for harsh environments
Especially designed for 'low noise and to operate under highly humid, highly dusty, highly oily, highly salty, ultra low or high temperature, heavily vibrating, high altitude and poor ventilation environment' application requirements, MEAN WELL has introduced the HEP family of high-class AC/DC power supplies.
Positrons are the latest tool for lithium ion battery research
Rechargeable lithium batteries with cathodes comprising nickel, manganese, and cobalt, are viewed as the most potent today. But they, too, have a limited lifespan. Already in the first cycle they lose up to ten percent of their capacity. Why this happens and what can be done to alleviate the ensuing gradual loss of capacity has now been investigated in detail by a team of scientists using positrons at the Technical University of Munich (TUM).
Desk-Top back up battery unit powers hubs and routers
Powersolve just introduced desk-top “mini” uninterruptible power supplies (UPS) that provide back-up power in the event of an AC mains failure. The compact PUPS22 & PUPS44 UPS’s works from a 12VDC input using any approved 12V AC-DC plug-top charger capable of powering the load and with enough output power to charge the internal batteries.
40A µModule regulator provides upstream load protection
Linear Technology Corporation introduces the LTM4636-1, a 40A to 240A scalable step-down µModule switching regulator. The part incorporates protection circuitry that trips a circuit breaker in the event of overvoltage or overtemperature fault conditions to protect itself, the PCB and loads such as high current low voltage processors, FPGAs, GPUs and ASICs.
Smart grid security takes centre stage at APEC
Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has announced that Chief Marketing and Communications Officer Patrick Le Fèvre will present a paper on the subject of ‘smart grid security’ at the Applied Power Electronics Conferences (APEC), 26th to 30th March 2017, in Tampa, Florida.
Rated voltage introduced with three times the power
Three times higher than the existing voltage of WE-CMB chokes, the rated voltage from Würth Elektronik eiSos, has the feature of the current-compensated power line chokes of the WE-CMB HV series.
Smart batttery features accurate fuel gauging
With the launch of its 492Wh Lithium Iron Phosphate (LiFePO4) smart battery, global battery manufacturer Ultralife is looking to enrich the U1 lead acid battery market.
