Dengrove adds “smallest 3W AC-DC” modules
Claimed to be the smallest 3W AC-DC power modules available to date, the RAC3 series by Recom is now available from Dengrove Electronic Components. The modules measure 28.5mm x 23.5mm x 17.9mm and deliver full load power from -40°C to 60°C, and 2 Watts up to 80°C. The modules also meet the latest European ErP Lot 6 ecodesign specifications for ...
Power boost to Components Bureau’s lineup
An agreement between Components Bureau and Artesyn covers the UK and Ireland, adding the latter’s high power modular and programmable power supplies to the distributor’s range, which includes AC/DC power supplies and DC/DC converters from a selection of manufacturers. Artesyn’s power offering ranges from products of 3W to hundreds of kW, for use in a variety of power supply control ...
1kW modular power supply is industry’s first fanless model, claims Relec
Claimed to be the industry’s first fanless 1kW modular power supply, the COOLX1000 from Advanced Energy is now available from Relec Electronics. It is designed for operation in sensitive environments, such as medical and scientific applications. The power supply measures 6.5 x 10-inch (165 x 254mm) and is 1U high. The U-channel design is based on patented, resonant technology. It ...
Researchers seek dc power grid circuit breakers
Georgia Tech is to develop circuit breakers for >1MW dc power links up to 100kV – with wind farms, electric aircraft and electric ships in mind. Direct current power transmission is more efficient than AC (see below), but high-power dc is far harder to interrupt than ac – there is no current zero crossing in which to switch and plenty ...
Low clamping voltage, high surge TVS devices protect USB Type-C PD in smartphones
Low clamping voltage, high surge transient voltage suppressors (TVS) from Alpha and Omega Semiconductor (AOS) are designed for Vbus protection. The AOZ8621UNI series of six TVS are suitable for USB Type-C Power Delivery (PD), in laptops and smartphones and any application using the PD protocol that can deliver up to 100W. The series covers a reverse working voltage (VRWM) range ...
UK pop-up EV charging point saves street clutter
Cheltenham-based design company Duku has developed a pop-up electric vehicle charge point, claiming it to be a world first. Six of them are on trial in Oxford. A pop-up design was adopted to reduce street clutter, but the amount of historical architecture and utilities under Oxford pavements meant minimal available underground space. “It’s an absolute mess below the pavement in many ...
