AC Power Sources now offered with DC Output Option

Pacific Power Source, Inc. has released its brand new DC Power Output option. Packaged as an add-on module to many of Pacific Power Sources’ programmable AC power source models, the new DCR600-20 adds DC output voltage programming up to 600Vdc and with up to 20Adc of output current per unit. Long a provider of precision programmable AC Power Source for development, test and production application of AC powered products, Pacific Power Source is now providing its customers with additional capabilities for testing DC products as well.

While general purpose programmable DC supplies are available from a wide range of suppliers, they have in common that they have limited DC voltage slew capability due to the amount of bulk storage capacitance at their output. This makes it difficult if not impossible to meet several avionics compliance test standards for DC Bus simulation which require very fast slew rates. Since the Pacific Power Source AMX Series of linear AC power source have a wide bandwidth no bulk capacitance on their output, they are capable of supporting the much higher voltage slew rates required for these tests.

With the addition of the DCR600-20 option, these AC Power Sources that have historically been used to perform AC power bus compliance testing will now also support DC testing. Examples of Avionics test standards that include DC bus testing are Mil-Std 704, RTCA/DO160 section 16, Airbus ABD and Boeing 747B3. Pacific Power Source already offers the broadest library of AC Power avionics test sequences in the industry, it is now expanding this portfolio with DC test sequences as well.

“We are excited to be able to offer this greatly expanded range of DC test capabilities to our customers who have been asking for us to fill this void in the marketplace. This new addition to our growing portfolio of products allows our customers to get increased use and value from their existing AC Power Source investment.” according to Herman van Eijkelenburg, Director of Marketing for Pacific Power Source.
