Products

Our products include wideband AC power amplifiers, AC power sources, linear frequency converters, and high frequency transformers. We also manufacture plasma power supply systems, high power piezo drivers and test systems.

The frequency range which our products cover is from 5 Hz – 800K Hz. The power ratings of our products range from 50 watts to 1500 watts as individual units. Multiple units can be combined for higher power ratings or for multiple-phase configurations.

Our products are utilized in applications such as testing of Helmholtz coils, piezo elements, circuit breakers, protective relays, lamps, watt-meters, transformers, inductors, capacitors, ferrite cores, etc. Our products are ideal for highly inductive loads and capacitive loads which require PD free powering.
Wideband Power Amplifiers

Wideband Power Amplifiers

The "HF-A" series wideband AC power amplifiers are with frequency response from 5 Hz to 800K Hz. The output voltage is 0 - 28 V rms. Custom output transformer(s) can be provided to achieve other output voltage (or current) ranges. 

AC Constant Current Sources

AC Constant Current Sources

Constant current sources provide steady output current independent of the load and input power line with variations.

AC Constant Current Power Amplifiers

AC Constant Current Power Amplifiers

Constant current power amplifiers take an input AC signal and provide steady output current independent of the load and input power line with variations.

AC Constant Voltage Sources / Amplifiers

AC Constant Voltage Sources / Amplifiers

Constant voltage sources and amplifiers provide a steady output voltage independent from the load and input power line with variations.

Multi-Phase Programmable Power Sources

Multi-Phase Programmable Power Sources

Multi-phase programmable power sources are phase angle adjustable constant current mode or constant voltage mode power sources.

Linear Frequency Converters

Linear Frequency Converters

The linear circuitry frequency converters are fixed frequency AC power sources. They are extremly useful for powering up capacitive and inductive loads which cannot stand the switching noises.

High Frequency Output Transformers

High Frequency Output Transformers

Custom high frequency transformers in the frequency range of 30 Hz to 800K Hz are avaialbe upon request. 

Plasma Power Supply Systems

Plasma Power Supply Systems

Plasma power supplies are high frequency high voltage systems for scientific research applications.  

High Power Piezo Drivers (Amplifiers)

High Power Piezo Drivers (Amplifiers)

High Power Piezo DriversHigh power piezo drivers are wideband AC power amplifiers with frequencies ranging from kilo Hertz to tens of hundreds of kilo Hertz. They are usually with adjustable DC bias function.

Test Systems

Test Systems

We produce Rate Check, Time Check, Ramp Check, Ultimate Trip, and Voltage Trip test systems using our programmable constant current sources as the core component.
