Magna-Power Debuts 1.5- to 4-kW 1U Programmable DC Supplies

February 5th, 2013. Magna-Power Electronics, a maker of high-power programmable DC power supplies, released to production its new SL Series 1U (1.75”-high) programmable DC power supplies. The SL Series offers 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 1000 VDC and current ratings ranging from 1.5 ADC to 250 ADC. 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, semiconductor burn-in, and battery charging.

All SL Series models come standard with front panel control, external 37-pin isolated analog and digital I/O, and an RS-232 interface. For computer communications, remote interface software is provided, along with Magna-Power Electronics' IVI driver, enabling programming from a variety of environments, including NI LabVIEW and Visual Studio. Load-dependent variable-speed fans are also standard on all models. Available options include an LXI TCP/IP Ethernet interface, an IEEE-488 GPIB Interface, a USB Edgeport interface, and a high slew rate output capability 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 (UI), allowing for an input voltage range spanning 85 VAC to 265 VAC. The universal input for the 1.5 kW models implements active power factor correction (PFC) 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 Electronics' first 1U product, building upon the company’s 2U rack-mount XR Series, which now offers power ratings from 2 kW to 8 kW. All of the company’s product lines, including the new SL Series, use the company’s current-fed power-processing topology to provide control and enhanced system protection, with a greater tolerance to abusive loads.

The new product series was designed and is manufactured at the company’s vertically integrated headquarters in Flemington, NJ. In early 2012, the company completed an expansion, which more than doubled its Flemington manufacturing facility and added a new research and development center. The company’s first international sales office, Magna-Power Electronics GmbH, was also opened in 2012. The company continued construction at its headquarters with the third phase of its manufacturing facility expansion, set for completion in early 2013.
