Industrial power solutions manufacturer, Powerstax, can now supply the upgraded range of Magna-Power SL Series 1U programmable DC power supplies. Now offering up to 95% efficiency and carrying a Nationally Recognised Testing Laboratory (NRTL) safety listing the SL Series is comprised of 99 different models.

The series combines the latest power semiconductor technology with Magna-Power’s signature robust current-fed power processing topology to deliver unmatched 1U programmable power levels from 1.5kW up to 8kW.

With its advanced microprocessor control and feature set, the SL Series provides the performance and functionality necessary to address cutting-edge applications, including aerospace test and measurement, automotive component testing, particle acceleration, semiconductor fabrication and component test, industrial and renewable energy, as well as general laboratory research and development.

The upgraded SL Series now boasts among the industry’s highest efficiency in its class, up to 95% efficient across a wide range of models, providing significant energy savings for automated test equipment (ATE) product validation and burn-in, as well as reduced enclosure cooling requirements. With its carefully planned internal cooling layout, air flows only across heatsinks via side air intakes with rear exhaust, not across sensitive electronics.

This layout, along with the SL Series efficiency gains, have allowed the product line to be expanded to higher power levels than is conventionally offered in a 1U package, while still maintaining its continuous full power operation at 50°C maximum ambient operating temperature.

The Magna-Power SL Series was introduced in 2015, and subsequent expansions in power range has now established it as their most popular product line.

“The SL Series is proof that power density is king for rack-mount programmable power supplies,” commented Phil James, Sales Director of Powerstax. “The SL Series efficiency gains and NRTL listing directly support our strong OEM customer-base, providing significant savings in energy costs and regulatory approvals for our customer’s products.”

In addition to the CE Mark the product line has carried since its introduction, the SL Series now carries an NRTL safety listing, meeting the relevant electrical safety standards testing requirements set forth by the United States Occupational Safety and Health Administration. The SL Series is now rated by Intertek to conform to UL61010-1:2012 Ed.3+R:29Apr2016 and certified to meet CSA C22.2#61010-1-12:2012 Ed.3. The SL Series Gen 2 is also released with all new HTML-based user documentation.

Powerstax designs and manufactures an extensive range of standard, value-added and custom AC and DC power solutions for a broad range of fixed and mobile applications including hot-swap front-end AC/DC bulk power, DC/DC converter bricks and modules and programmable, modular, rack mounted power supplies. Their High Voltage DC power capability extends up to 350kV for industrial processes, capacitor chargers and electron beam power systems.

The Powerstax Drake range of transformer rectifiers offer output currents to 5,000A and output power up to 1,000kVA and beyond. Power solutions are available for harsh (marine, offshore, desert) and hazardous (Zone 1 and Zone 2) environments and can be oil, air or water cooled and can be sealed up to IP65 if the environment dictates with purge and pressure systems and heat exchangers incorporated if required

The main markets served by Powerstax include high-end industrial, defence, vehicle and transportation, defence and avionics, impressed current cathodic protection, water treatment, test, measurement and control and medical equipment.
