APS3000 Series Frequency Converters

Three Phase Output Frequency Converters

The APS3000 Series frequency and voltage converters  (DISCONTINUED)

IMPORTANT NOTICE: This product line has been discontinued. 

The series consists of six three phase output instruments ranging in size from 15kVA to 150kVA. The converters allow the user to duplicate a utility grid of either 50 or 60 hertz for export product testing or operation of imported equipment or 400Hz power for avionics and shipboard applications.

For questions regarding the APS3000 Series, please contact us.


The APS3000 Series converters allow the user to duplicate a three phase utility grid of either 50 or 60 Hertz for export product testing or operation of imported equipment. With its ability to power multiple AC products simultaneously, the APS3000 models are ideally suited for burn-in and test of large industrial equipment. The frequency can also 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 500 Hertz in conjunction with the dual voltage ranges of 0-150 volts or 0-300 volts provides full capabilities for testing and operating electronics worldwide.

Setup and operation of the APS 3000 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 of each phase.

The APS 3000 series converters are a simple and cost effective solution for all of your higher power three phase AC power conversion needs!

AC Test Power

The APS3000 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 APS3000 Series is an excellent source of stable three phase AC voltage over a frequency range of 45 to 500 Hz. The output frequency is quartz-crystal stabilized. Output voltages up to 300 VAC or 600V are provided.

Export/Import Product Development and Test

With the ability to provide any three-phase or split phase voltage and frequency combination found around the world, the APS3000 Series is a great choice for evaluating AC products for worldwide use. In particular, heavy duty electrical equipment and transformers intended for export to regions of the world with various utility grid voltage and frequency combinations can be tested in high volume using the higher power APS3000 models.

Avionics Power

Whenever 400Hz, 200Vac three phase Line-to-Line is required to power up shipboard or airborne equipment, the APS3000 can do the job. With up to 336A of current per phase available, even large equipment can be powered up.
