Powerbox has released a 700W power supply for industrial applications. OFI700A measures 126 x 38 x 250mm (0.95kg max) in open frame form and 126 x 40 x 250mm (1.1kg) with its (Optional N) metal cover. Optimised for conduction cooling, it can run with the baseplate between -40 to +95°C without a fan – with derating caveats. “There are applications ...

Power supplies are increasingly expected to reach heightened levels of efficiency, while still being as compact as possible, affordable and of course reliable and safe, writes Jan Fischer of Nexperia. One company overcoming these design challenges is Recom — an Austrian manufacturer of AC/DC power supplies and DC/DC. For a recent project, Recom wanted to develop a power supply which ...

Chinese GaN device maker Innoscience is introducing a bi-directional transistor amongest its more conventional devices. Called INN40W08, it is a 40V device that can block in both directions (unlike single silicon mosfets where two are needed for bi-directional operation). Innoswitch announced an up-dated version here Nominally it has a gate, two drains and no source. The company sees it being ...

Omron has launched its second high in-rush relay in a month, this time aimed at energy storage for solar panels or vehicle-to-home charging – the previous one was for smart lighting. Called G5PZ-X, it is a PCB-mount 200Vdc 20A SPST-NO relay with a 15.2 x 26.4mm footprint, and designed so that two can be connected in series to switch 400Vdc 20A. “This level of ...

In the US state of Illionois, nine coal power stations are being converted into batteries, some with local solar generation. The sites were aquired by a Texas company called Vistra in 2018, and coal burning is being terminated for a variety of reasons including running costs and legal decision over pollution. Power station  Net coal generating capacity Planned solar generating ...

Infineon is aiming at high switching frequency applications dc-dc converter applications such as telecom and solar with its OptiMOS 6 family of 100V mosfets. Compared with OptiMOS 5, the company is claiming: Rds(on) better by 18% Qg x Rds(on) better by 29% Qgd x Rds(on) better by 42% “In a 600W, 36-60V to 12V zero-voltage switched buck-boost converter, OptiMOS 6 in SuperSO8 with 2.2mΩ can achieve 1% ...

Renesas has introduced a battery pack monitor for long strings of cells that uses an ac-coupled bus to solve the thorny problem of passing data up and down the line. At the same time, it revealed a high-side battery protection and monitoring IC for 4S to 16S cell battery packs. RAA489204 for long strings Stackable up to 30 ICs Up ...

Power Integrations has used GaN switching to in a reference design for a 100W USB Power Delivery (PD 3.0) charger and USB programmable power supply (PPS). From 90 – 265Vac in can deliver 5A at 5, 9, 12, 15 or 20V, or 3.3 – 21V at 5A (up to 100W). The design, DER-937, contains: specification, schematic, PCB layout, bill of materials, detailed magnetics specifications ...

Trinamic will be demonstrating motor control through Python programming at Smart Production Solutions (SPS 2021) the week after next – for the first time under the Analog Devices flag along with Maxim. Intended to ease prototyping, the company’s TMCM-0960-MotionPy single-board computer (right) runs MicroPython on an Arm Cortex-M4, works over 6V to 50V, and includes CAN, RS485 and UART interfaces as ...

Netherlands-based Delta Elektronika has added a 210V variant to its SM15K family of 15kW bi-directional power supplies. Fitting into a 3U rack slot and called SM210-CP-150, its output is bounded (curve below) by 15kW maximum power, +210V maximum voltage and ±150A maximum current. Within its range it can output:  210V, ±71.5A 150V, ±100A 100V, ±150A Up to 20 can be paralleled ...
