Powerbox adds Standard Industrial Power Offering

October 21, 2015 by Jeff Shepard

Powerbox introduces its new Industrial Line of standard ac-dc power supplies. With over 200+ products covering a wide span in power, output voltages, mechanical format and cooling options, the Industrial Line of products is a comprehensive product portfolio, aimed at some of the most demanding applications in electronics.

This new product line compliments the company’ non-standard power solution capabilities, widening the product range to cover a variety of applications and requirements. The product line comprises single, dual and multiple output converters in the power range from 150- to 650-W. Mechanical formats include open frame, U-channel, enclosed, and a version offering full power at natural convection with -20 to +50 degrees C operating temperature.

“The Industrial segment, with applications like ICT, automation, building control, test and measurement, etc. is wide-ranging”, says Martin Fredmark, VP Product Management, “But there are substantial similarities in what customers require. For example, high power density and low heat generation, making integration in applications simpler, are often prerequisites in most designs today. Fulfilling standards that affect where the products can be used is also essential, as is high-reliability and exceptional field support. And, of course, we need to ensure we help customers meet their marketplace requirements with environmental considerations and low energy consumption. The new Powerbox Industrial Line range of power supplies has been designed to address all these pertinent issues.”

The single output converters utilize an LLC half-bridge topology for many of the units, complimented by synchronous rectification, where the rectifier output diodes are replaced by MOSFETs. These technologies contribute to characteristics such as high-efficiency (up to 93%), high energy density, high peak output current, and superior EMI performance, meeting and surpassing EN55022B.

Other Industrial Line characteristics include wide input voltage range, low no-load consumption and high MTBF. All units have PFC and meet EN61000-3-2 class D. The low no-load consumption, in combination with high-efficiency, offer an environmental friendly energy profile.
