Powerbox’s S-CAP BOOST technology delivers peak power and safety to industrial and medical applications




Powerbox, one of Europe’s largest power supply companies, and for more than four decades a leading force in optimizing power solutions for demanding applications, announces the introduction of its supercapacitor boost technology, S-CAP BOOST, offering backup and peak power solutions to industrial and medical applications. Based on the latest supercapacitor technology combined with intelligent control and monitoring, S-CAP BOOST offers a solution to equipment manufacturers requiring high energy peaks for short periods or emergency backup purposes in applications where due to safety regulations, Lithium Ion or acid batteries are not allowed. Depending on the application, S-CAP BOOST can be configured to charge and monitor supercapacitor banks to work as UPS, delivering backup power to allow safety operations to take place before shutdown or delivering high peak power for a short period without disturbing the main source or discharging/damaging the system battery in applications such as laser, electric motor booster or X-ray emission element.

Critical applications operating in hostile or confined environments are strictly regulated in terms of chemical and other hazardous risks, reducing or forbidding certain type of batteries such as Lithium Ion. For safety reasons, those applications must have a power backup long enough to run alarms and safety shutdown processes. In such arduous conditions conventional batteries are replaced by supercapacitor banks whose values could be from few Farads to 200 Farads for general applications, but up to container size in the case of large systems. S-CAP BOOST technology tightly controls vital parameters, from a single 2.8V cell supercapacitor to a wide range of assemblies delivering a specific voltage and energy required for a given application.

One example of a product built using Powerbox’s S-CAP BOOST technology is a 2500W backup unit developed for an industrial process-control computer installed in a very restricted area. Housed in a 19 inch 2U chassis, the 29F-54V-60A integrates 22 supercapacitors totaling 29 Farads and has a capacity of 2500W during 5 seconds at full load and 30 seconds at half-load. To optimize the cells charge, the 29F-54V-60A integrates a DC/DC converter with current control, guaranteeing the supercapacitors are properly charged to deliver full power when required. The unit includes active charging cells control with load balancing, cell health monitoring and alarms. Alarms signals including Vcell-high, Vcell-low, Vcell-zero and temperature are available via a physical interface, with digital control and monitoring being an alternative option.

“The number of applications requiring emergency backup or high peak current are growing, and integrating supercapacitors within power supplies is becoming an extremely reliable and well suited option to be considered by system architects.” said Patrick Le Fèvre, Powerbox’s Chief Marketing and Communication Officer. “Powerbox’s S-CAP BOOST is a great platform for the future and we foresee an impressive number of applications for supercapacitor energy storage technology, and not only for electrical vehicles.”

Compared to Lithium Ion which has a cyclability (number of recharges) of 500 to 1,000, supercapacitors can sustain from 500,000 to 20,000,000 cycles, making that technology extremely relevant for applications requiring large amounts of charge /discharge cycles with high energy such as industrial or medical lasers. This is what S-CAP BOOST technology has been developed for, very tight control of the supercapacitors’ charge in order to optimize the energy stored between each cycle, with very high levels of safety and reliability.

Powerbox presents flexible and adaptable Enhanced Rail Power Solutions at Innotrans 2018












The Powerbox Group, one of Europe’s largest power supply companies and a leading force in optimizing power solutions for demanding applications, has announced that it will be showcasing its PRBX Enhanced Rail Power Solutions (PRBX-ERPS) at Innotrans 2018 in Berlin, 18 – 21 September 2018, Hall 17, Booth 103. From low power board-mounted DC/DC converters up to fully customized power solutions delivering multi-kilowatts, PRBX-ERPS is one of the most flexible and adaptable power solutions for railway applications. Designed to reduce time to market and meet specific rail industry requirements, PRBX-ERPS building blocks and solutions are tailored to adjust performance and parameters quickly, reducing time to market for new equipment, time to modernization for renovation and refurbishing, and inventories and their associated costs. PRBX-ERPS flexibility is built on three pillars: board-mounted AC/DC and DC/DC solutions, modular solutions integrating modules, filters and collaterals, and DIN rail, cassettes and racks when the PRBX-ERPS adaptability relies on the extensive custom power solution library, which includes more than 3500 released projects.

As part of PRBX-ERPS, PRBX will present its latest series of advanced DC/DC converters that includes a range of 8 to 20W, board-mounted DC/DC units designed to meet railway specifications EN50155, EN50121-3-2, EN61373 and EN45545. With an impressive input voltage range of 13:1, and covering from 12 to 160V, the MAD33 (8W), MAD32 (10W), MAE35 (15W) and MAF35 (20W) are the Swiss army knife of power-systems designers, bringing simplicity to complex applications. A single part number is able to power a large range of transportation applications, reducing inventory and time to market. All products are manufactured using industry standard packaging and pinouts. The extra-wide series of DC/DC converters are suitable for low power loads and devices in railway applications such as communication devices, GSM-R phones and their docking stations, routers/Wi-Fi access points, small screens, USB charging sockets (both in-seat and driver’s cabin), sensors, and standby power for larger devices. The series is complemented by the 4:1 series of DC/DC converters delivering up to 600W with paralleling capability for extra power.

At its booth Powerbox will present a series of products and solutions designed for adaptability when customers are facing the challenging demands of refurbishing, modernization and/or upgrades. In such applications Powerbox is able to call on its extensive knowledge base that with more than 3,500 custom solutions delivered to market, represents a huge depth of knowledge forged in an industry in which it has excelled for more than 40 years.

Powerbox will also be sharing the latest company news regarding the acquisition of the Powerbox Group by the leading Japanese power supplies manufacturer COSEL and the benefits of joint forces and a combined offering.
