February 04, 2013 by Jeff Shepard

Magna-Power Electronics has released to production its new SL Series 1U programmable DC power supply. The SL Series continues the company's commitment to market-leading power density, offering models ranging from 1.5 kW to 4 kW, all in a 1U rack-mount package. The new SL Series is released with 54 different models, with voltage ratings ranging from 5 Vdc to 1,000 Vdc and current ratings ranging from 1.5 to 250 Amps. With extensive interfaces and controls, the new series satisfies the requirements for a wide range of applications, including: automated test equipment (ATE), automotive and hybrid/electric development, semi-conductor burn-in, battery charging, among a wide variety of research and development activities.

All SL Series models come standard with front panel control, external 37-pin isolated analog and digital I/O, and a RS232 computer programming interface. For computer communications, Remote Interface Software is provided, along with Magna-Power Electronics IVI Driver, enabling programming from a variety of environments, including LabVIEW and Visual Studio. Load-dependent variable speed fans are also standard on all models. Available options include: LXI TCP/IP Ethernet Interface (+LXI), IEEE-488 GPIB Interface (+GPIB), USB Edgeport (+USB), and High Slew Rate Output (+HS) for fast output transitions. Master/slave operation will be available with the UID47 device, enabling multiple units to be tied in series or parallel.

All SL Series models are available with three-phase input, including 208/240 Vac, 380/415 Vac, or 440/480 Vac. 1.5 kW models are also available with a new single-phase universal input of 85 to 265 Vac. The Universal Input for the 1.5 kW models implements active power factor correction for a 0.99 power factor at maximum load, keeping input current draw to a minimum.

The new SL Series product line is Magna-Power's first 1U product, building upon the company's 2U rack-mount XR Series, which now spans from 2 kW to 8 kW. All of the company's product lines, including the new SL Series, use the company's signature current-fed power processing topology to deliver superior control and enhanced system protection, with a greater tolerance to abusive loads.
