CGS100 Series AC and DC Power Sources

Single Phase Programmable AC and DC Power Sources

The CGS100 Series programmable AC or DC output power sources are cost effective source of power for development, test and production applications requiring anywhere from 500VA to 4000VA of single phase AC or DC output.

This series consists of four models, CGS105, CGS112, CGS120 and CGS140. All models share a modern PWM switch mode converter design for optimal performance and efficiency. These units are excellent source for 50, 60 or 400 Hertz for export product testing as well as testing DC powered equipment.

For questions regarding the CGS100 Series, please contact us.


The CGS100 Series programmable AC and DC output power sources are easy to use instruments which provide precisely controlled frequency and voltage conversion. The frequency can be adjusted from 40 to 500 Hertz for applications such as the testing of military/avionics equipment or for the operation of 400 Hertz electronics that are onboard an aircraft or a military vessel. The adjustable frequency band in conjunction with the dual voltage ranges of 0-150 volt or 0-300 volt as well as DC test capability provides full capabilities for testing and operating electronics deployed worldwide.

Setup and operation of the CGS100 Series is easy. The large color LCD display and simple front panel controls allows users to vary voltage and frequency using the shuttle or by entering a value directly using the decimal keypad. The LCD displays readouts for frequency, voltage, current, peak current, crest factor, power, apparent power and power factor.

The CGS100 Series power sources are a reliable and cost effective solutions for all of your single phase AC power and DC power needs!

AC or DC Test Power

The CGS100 Series Power Sources are equipped with a powerful microcontroller to create a stable and accurate output, regardless of AC input line conditions. It can be programmed to supply a variety of AC or DC power conditions to the device under test and meters all output parameters.

Frequency/Voltage Conversion

The CGS100 Series is an excellent source of stable AC voltage over a frequency range of 40 to 450 Hz. The output frequency is quartz-crystal stabilized. Output voltages up to 310 VAC are provided.

Export/Import Product Development and Test

With the ability to provide any single phase voltage and frequency combination found around the world, the CGS100 Series is a great choice for evaluating AC power input supplies for worldwide use.

DC Testing

The CGS100 Series includes a DC output mode that allows for development or testing of DC powered products up to 420 Vdc. Current and power limit are available in DC mode as well.

Avionics Power

Whenever 400Hz, 115Vac single phase is required to power up shipboard or airborne equipment, the CFS100 can do the job. With up to 40.0 A of current available (Model CGS140), most single phase input equipment can be powered up for repair or test purposes.
