High current temperature rise test device (Hangzhou, Yangzhou)

Other name

High current temperature rise test deviceVariable magnetic flux three-phase high current generator, high current generator three-phase current booster

Product Overview

In order to meet the requirements of long-term three-phase high current temperature rise tests for cable or busbar plates and switch circuit breakers, our company's new high-power control cabinet voltage regulator product, the electric voltage regulator, has an output voltage waveform that is not distorted (output voltage waveform distortion rate increment<1%). The electric voltage regulator adopts a stepper motor operating mechanism to reduce operational labor intensity, achieve intelligent control with a microcomputer, and output current can be smoothly adjusted from zero voltage, with strong instantaneous overload capacity, low no-load current and no-load loss, high efficiency, low noise, and long service life. Suitable for various inductive, capacitive, and resistive loads. This product is widely used in petroleum, chemical, metallurgical, electromechanical, textile, medical, power testing, scientific research and other departments to achieve the purpose of voltage regulation, temperature control, dimming, and power control.

Features

Our company's voltage regulator products use high-quality electromagnetic materials, advanced manufacturing processes, and strict quality management, making them have the characteristics of small size, light weight, low waveform distortion, low noise, and low no-load loss. In the key parts of power transmission, we have selected the "A" type electric brush imported from the UK, which has better wear resistance, overload capacity, and low temperature rise than traditional accessories. Fine tuning part, using domestic special technology.
