New 5 kW Multi-Range Programmable dc power supplies

Actum merges its brands

O ver the years, Actum Group has been built through partnerships, collaborations and acquisitions of leading companies with a long history and rich legacy in the industry. These companies include Actum Electronics, Dowson & Dobson Indus- trial, Peter Jones Electronic Equipment, Altico Static Control Solutions and, most recently, Banding & Identification Solutions Africa. In order to simplify its product offering and deliver the best service to customers, it has decided to consolidate all the company brands to form Actum Group. The company’s team and product offering has not changed; it will simply promote everything under this overarching brand from now on. Actum Group director, Kevin Klaff, explains the reasoning behind adopting Actum Group as the flagship company brand: “The key to our ongoing success is our product offering of specialised quality products. Over the years we have partnered with leading suppliers in the industry to offer our customers quality that they won’t find elsewhere. “Through improved communication, stock management and lead times, we have signifi- cantly improved our customer service and aim to continue doing so. By consolidating all our company brands under Actum Group, we simplify our product offering and give our customers a one-stop solution to access all the products and brands they need.” Actum Group is a specialised importer and distributor of industrial and electronic prod- ucts in South and Southern Africa. Its world touches everything from agriculture and tel- ecoms, to pharmaceutical and construction, to automotive, mining and oil and gas. The group is fanatically focused on quality and proudly represents only the best international and local companies and brands.

of industry standard interfaces combined with excellent regulation and low noise characteristics. Compared to the N8900A Series from Keysight, the MR Series is a worthy competitor and deserves a closer look. Consider the fact that it includes faster command response times (10 ms vs. 25 ms), a single-phase ac input, a built-in solar array simulator, and higher power density (2U vs. 3U form factor), all at a significantly lower price point. B&K Precision’s MR Series has a three-year warranty and includes a User Manual (downloadable), Certificate of Calibration, Test Report and ac Power Cord. Op- tional accessories include a RKPVS Rack Mount Kit and SASPVS Solar Array Simulation Software.

B&K PRECISION’S new MR Series of 5 kW multi-ranging, single-output programmable dc power supplies, avail- able through Comtest, offers up to 1000 V or 80 A in a compact 2U form factor. Well suited to bench use and automated test system applications, B&K Precision’s MR Series offers multi-range functionality and provides us- ers with added flexibility in the form of additional voltage and current combinations, capable of replacing multiple fixed-range power supplies. The MR Series is B&K Precision’s first cTUVus certified instrument family. The cTUVus certification mark dem- onstrates compliance with CSA and UL safety standards. Another first is the LXI compliant LAN interface and IVI drivers, which simplify system development, and integra- tion. In addition, the MR Series provides a wealth of the features customers have to expect, such as a wide range

Chrome industrial power-supply series from Delta

Dc-dc converters deliver power to isolated circuits

The UCC12050 and UCC12040 con- verters are supported by the UCC12050E- VM-022 evaluation module. This allows designers to evaluate the abilities and per- formance characteristics of the two con- verters, with an EVM layout that provides an example of a proper board layout for rated isolation and EMI performance. As an authorised TI distributor, Mouser Electronics offers the broadest portfolio of the latest semiconductor solutions from Texas Instruments, adding new products daily. It is focused on the rapid introduc- tion of new products and technologies, giv- ing customers an edge and helping speed time to market. Over 800 semiconductor and electronic component manufacturers count on Mouser to help them introduce their products into the global marketplace. Mouser’s customers can expect 100% cer- tified, genuine products that are fully trace- able from each manufacturer. With its broad product line-up and effi- cient customer service, Mouser strives to empower innovation among design engi- neers and buyers by delivering advanced technologies. It stocks the widest selection of the latest semiconductors and elec- tronic components for new design projects.

MOUSER ELECTRONICS INC. carries the widest selection of semiconductors and electronic components and is now stock- ing UCC12050 and UCC12040 isolated dc-dc converters from Texas Instruments (TI). The high-efficiency converters are de- signed to provide efficient, isolated power to circuits that require a bias supply with well-regulated output voltages. The devices are ideal for a range of applications, includ- ing protection relays and smart breakers, PLC analogue input and output modules, patient monitoring, and isolated voltage and current sensing. TI’s UCC12050 and UCC12040 con- verters use a proprietary architecture to in- tegrate a transformer and dc-dc controller,

T he Chrome series of industrial power supplies from Delta, the world’s number one power supply manufacturer, is available from ElectroMechanica (EM). Circuit breakers (h) 91 x (d) 55.6 mm with only (w), influenced by output 10 W/18 mm, 30 W/53 mm, 60 W/71 mm and 91.2 W/90 mm: These compact, high- efficiency power supplies are ideal for installations in small cabinets and domestic and commercial distribu- tion board applications. They feature Class II double insulation with a universal input voltage range of 90…264 Vac at 47 to 63 Hz, with no deration for the entire voltage range. Available with 5, 12 and 24 V dc outputs, they provide full power up to 55⁰C in 10, 30, 60 and 91.2 Watt NEC

Class 2 and Limited Power Source approvals. In addition, they conform to harmonic current IEC/EN 6100-3-2 Class A, with safety approvals in accordance with IEC/EN/UL 60950-1 and UL 508 (industrial stand- ard). The power series is complemented by dc-UPS module DRU-2410ACZ suitable for 24 V systems when connect- ed to an external battery, with zero switchover time from loss of dc input to battery operation for secure, main- tained supply even after mains failure. Additional features are built-in diagnostic monitoring and frontal LED indication of dc OK, Battery Charging, Battery Discharging, Battery Fail and Reverse Polarity.
