Functions and Advantages

Linear amplification technology

The IT7321 AC Power Supply adopts advanced and high-precision linear amplification design to provide low noise and high stability output. This technology has high-speed response characteristics, stable low noise, it can simulate the abnormal power line, instantaneous voltage rise, drop and power off, and can be applied to ATE and so on.

TRIAC Dimmer simulation function

ITECH is the pioneer of TRIAC Dimmer function.This function is used to do dimming and speed regulating test for lamp or electric motor to ensure the products work well when controller of dimming and speed regulating is needed.

Front edge phase dimming

Back edge phase dimming

No power frequency transformer power supply, low power consumption

The IT7300 series AC source provide no power frequency transformer power supply with lower power consumption, it solves output problems of large volume, large heat dissipation and low power caused by using frequency transformer , IT7300 series also provide linear adaptation method between the current and AC voltage in AC source, which solves the problem of high energy consumption and low accuracy.

List function

The IT7300 series has a built-in DDS waveform generator, that has a very flexible waveform simulation function. Users can directly set the required power waveform through the panel keys, it can simulate transient power off, surge, trap, specific phase angle on or off, AC sine wave amplitude and frequency range and other characteristics.
