MSZW Intelligent Contactless Compensation Stabilizer

Description

Overview
This intelligent non-contact compensating AC voltage stabilizer adopts high-speed DSP arithmetic chip control technology, fast AC sampling technology, RMS correction technology, voltage and current zero-crossing switching technology and fast compensation voltage stabilization technology. Combined with fault diagnosis, the product is safe, efficient and precise. 
 
The voltage stabilizer is mainly composed of isolation transformer, SCR thyristor module, DSP control core, fast voltage stabilization technology and safety protection device. Through DSP, the output voltage is monitored in real time.  The SCR thyristor module with quick calculation and controlled adjusts the voltage and polarity of the primary side of the compensation transformer connected in series at the load end, achieving the goal of fast voltage stabilization.
 
Applicable scope
The products are widely used in large electromechanical equipment, metal processing equipment, production lines, elevators, medical equipment, embroidery and textile equipment, air conditioning, broadcasting and television, household appliances, and building lighting that require stable voltage in industries, transportation, postal and telecommunications, national defense, railways, scientific research, and other fields.
 
Product Features
●High efficiency: more than 98%, its lower own loss
●High precision: voltage regulation accuracy ±1%
●Intelligent instrument display: real-time display of voltage and current RMS, clear, accurate, high resolution, membrane key operation, safe and reliable
●Three-phase sub-adjustment: The three-phase adjusted separately to ensure that the accuracy of the output voltage of each phase remains unchanged.
●Wide range of application: wide range of voltage regulation, which can meet the needs on occasion of poor power quality and wide range voltage fluctuation
●Quick response: 40 millisecond voltage regulation, no voltage change effect on any computer automation, equipment and instruments
●Complete protection functions: equipped with fault display or protection functions such as phase loss, phase error, over-temperature, overload, over-voltage, under-voltage, short circuit, fuse blown, etc., to ensure the safe operation of the voltage stabilizer and load
●Strong preset function: output voltage, overload, over-voltage and under-voltage, response time and other parameters can be freely set within the rated value of the product
●Strong overload capacity: The whole machine adopts high-quality components, with good performance, can be used continuously under 100% rated load conditions, and can withstand instantaneous overload without damaging the regulator
● Strong adaptability: It has strong adaptability to the power grid and load, and can work continuously and stably under various harsh power grid and complex load conditions.
●No distortion: Adopt voltage and current zero-crossing switching technology, no interruption, no inrush current during the switching process, and no distortion of the output waveform
●Low loss: no-load loss under rated voltage is less than 0.5%, saving much electricity expense
●Bypass function, easy to maintain: It can be switched between "stabilized voltage" and "bypass direct power supply", which is convenient for use in fault maintenance
