Product Introduction

Brief Description:

GDYT-10kW PD free induced voltage test set is a variable frequency AC power supply (hereinafter called VF power supply). It inputs single AC voltage and frequency, after inversion, it generates stable and pure sine wave.

The equipment uses PWM (Pulse Width Modulation) technology to make the device small size, light weight and highly efficient. Digital signal processing technology provides high-precision and high-speed measurement functions such as voltage, frequency, current, apparent power, and power factor. Meanwhile, it uses high-power IGBT module design to reduce circuit complexity, improve product stability, reduce power consumption, and increase the capacity of a single unit, plus a number of ultra-isolation transformers to completely isolate the mains and the load to increase the functions, which can ensure the accuracy.
