Military-Standard rated option for popular SL power supplies series

Magna-Power Electronics, a leader in programmable power products worldwide, announced the immediate availability of a new Military-Standard (MIL-STD) rated ruggedized option for its popular SL series and XR series programmable DC power supplies. Tested to MIL-STD-810G functional shock and vibration specifications, the new Ruggedized Option (+RUG) is now available on 235 models spanning power levels 1.5kW to 10kW, voltage levels from 5VDC to 10,000VDC and current levels from 0.2 to 600ADC.

The Ruggedized Option, specified at time of order with option code +RUG, allows Magna-Power’s commercial programmable DC power supplies to be integrated in applications that have high levels of shock and vibration.

“Magna-Power products are designed for a broad range of applications An assortment of build options are configured at time of order that tailor a product’s performance and functionality to best satisfy customer requirements,” said Grant Pitel, Magna-Power’s Vice President of Engineering. “The new ruggedization option continues Magna-Power’s design trend, in this case, by allowing the company’s economical Commercial Off-The-Shelf (COTS) power supplies to be applied in high shock and vibration applications that have historically required specialized solutions.”

With the new Ruggedized Option, the 1U SL series spanning 1.5 to 8kW and the 2U XR series, spanning 2 to 10kW are rated to comply the following standards:

  • MIL-STD-810G CHG1 Method 516.7 Functional Shock, Procedure I; which subjects the product to 40G, 11 ms terminal saw tooth pulse; three shocks in each direction along three mutually perpendicular axes.
  • MIL-STD-810G CHG1 Method 514.7 Vibration; which subjects the product to two hours per axis along three mutually perpendicular axes.

All SL series and XR series models come standard with monitoring and control from a variety of sources, including: front panel, computer interface and an isolated analog-digital I/O connector. A Standard Commands for Programmable Instrumentation (SCPI) command set is supported, allowing easy ASCII text programming over a computer interface. In addition, an IVI driver is included for the Visual Studio programming environment along with a dedicated National Instruments LabVIEW and LabWindows driver. Additional computer interface options include LXI TCP/IP Ethernet (+LXI), IEEE-488 GPIB (+GPIB), USB and RS-485.

SL series and XR series models are available with three-phase input, including 208, 240, 380, 415, 440, or 480VAC. In addition, 1.5kW models are also available with a single-phase active PFC Universal Input (UI), allowing for an input voltage range spanning 85 to 265VAC.

All Magna-Power products are designed and manufactured at the company’s vertically integrated headquarters in Flemington, New Jersey USA. The company’s products are available directly from Magna-Power in the USA, through Magna-Power sales offices in the Germany, United Kingdom, and China or from a network of distributors in over 40 countries worldwide.
