Phase High Precision Automatic AC Voltage Regulator TND3-5KVA Low Voltage

ZHENGXI (TND3-5KVA low voltage) Phase high precision automatic AC voltage regulator working principle Its structure consists of contact auto-coupler voltage regulator, servo motor, automatic control circuit, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor to adjust the auto-coupling voltage regulator carbon brush. Position, adjust the output voltage to the rated value and reach a steady state. Features l High efficiency: 98% or more, its own loss is small l High precision: voltage regulation accuracy ± 4% l Intelligent instrument display: real-time display voltage is clear, accurate, high resolution, safe and reliable l Wide application range: wide voltage regulation range, can meet the needs of places and equipment with poor power supply grid quality and large voltage fluctuation range l High-speed response: 1 second regulation speed, no voltage change is affected by any computer automation, equipment and instruments l Complete protection functions: overload, overvoltage, short circuit, and other fault display or protection functions to ensure safe operation of the regulator and load l Preset function is strong: output voltage, overload, over-voltage and under-voltage, etc. can be set arbitrarily within the product rating l Strong overload capability: The whole machine adopts high-quality components, has good performance, can be used continuously under 100% rated load conditions, and can withstand transient overload without damaging the machine. l Adaptability: It has strong adaptability to power grid and load, and can work stably and continuously under various harsh power grids and complicated load conditions. l No distortion: using voltage and current zero-crossing switching technology, no interruption current, no inrush current during switching, no distortion of output waveform l Low loss: no-load loss less than 0.5% at rated voltage, saving customers a lot of electricity bills Scope of application Products are widely used in industrial, transportation, post and telecommunications, national defense, railway, scientific research and other fields of large-scale electromechanical equipment, metal processing equipment, production lines, elevators, medical equipment, embroidery textile equipment, air conditioning, radio and television, household appliances and building lighting, etc. A consumer that needs a stable voltage.
