FC300 Series Bench-top Frequency Converters


The FC300 Series frequency and voltage converters are economically priced and offer top of the line performance.

The series consists of two 1 phase output instruments in size of 500VA and 1000VA. The converters allow the user to duplicate a utility grid of either 50, 60 or 400 Hertz for export product testing or operation of imported equipment.

For questions regarding the FC300 Series, please contact us.


The FC300 Series frequency and voltage converters are easy to use instruments which provide reliable frequency and voltage conversion. The frequency can be adjusted to 400 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 of 45 to 450 Hertz in conjunction with the dual voltage ranges of 0-155 volts or 0-310 volts provides full capabilities for testing and operating electronics worldwide.

Setup and operation of the FC300 Series is exceptionally easy. The simple front panel layout allows users to continuously vary voltage and frequency or to select preset standard frequency settings. Individual meter displays provide digital readouts for frequency, voltage, current and power or power factor.

The FC300 Series converters are a simple and cost effective solution for all of your lower power AC power conversion needs!

AC Test Power

The FC300 Series Power Source is equipped with a powerful microcontroller to create a stable and accurate output frequency, regardless of AC input conditions. It can be programmed to supply a variety of power conditions to the device under test and meters all output parameters.

Frequency/Voltage Conversion

The FC300 Series is an excellent source of stable AC voltage over a frequency range of 45 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 FC300 Series is a great choice for evaluating AC power input supplies for worldwide use.

Avionics Power

Whenever 400Hz, 115Vac single phase is required to power up shipboard or airborne equipment, the FC300 can do the job. With up to 9.2 A of current available, most single phase input equipment can be powered up for repair or test purposes.
