Product Introduction

working principle

Adopting microcomputer (MCU+PLD+12 bit high-speed AD) intelligent detection, the output command controls the fast switching of electronic modules (IGBT or SCR), and maintains the stability of output voltage through transformer frequency synchronization, phase locking, and sine wave superposition compensation. Fast response speed, no carbon brushes, no contacts, no machinery, automatic balancing of three-phase voltage.

Applicable to various CNC machining centers, medical equipment, printing machinery equipment, environmental testing equipment, electronic detection equipment, communication equipment, etc., especially suitable for harsh power supply environments such as large fluctuations in the power grid and sudden voltage changes.

Performance Characteristics

Fast response speed	12 bit high-speed AD acquisition, 64 points per week wave acquisition, digital processing and calculation by microcontroller, and fast compensation by electronic module
Multiple adjustment methods can be set	Same tone: When setting the same tone, AD simultaneously collects the true effective values of A, B, and C three-phase voltages for average calculation, and gives instructions for compensation, which can effectively improve the imbalance of three-phase voltages
	Split adjustment: When setting split adjustment, the three-phase voltage is adjusted separately to ensure that the three-phase voltage is within the accuracy range, which is particularly suitable for single-phase loads
	Mixed adjustment: Microcomputer automatic analysis should be synchronized or divided
Advanced measurement technology	12 bit AD acquisition, digital filtering and true RMS calculation by microcontroller
Accurate and error free control	The perfect combination of large-scale programmable logic devices and microcontrollers
Humanized interface	Various indicators (output voltage, voltage stabilization accuracy, protection function) can be set through the touch keys on the operation panel
Output waveform without distortion	Non contact zero crossing switch switching, same frequency, phase-locked, sine wave superposition compensation principle
Resist harmonic interference	True RMS voltage detection
Wide load range	Resistive, capacitive, and inductive loads can all adapt
Slow start and shock resistance	It has the function of stabilizing voltage before output
Full protection function	When overvoltage or undervoltage occurs, it can be protected within 1 second or automatically switched to bypass operation without interruption, and has complete phase loss, overload, short circuit protection and sound and light alarm functions after faults
Voltage and current display	Digital display of true effective values for voltage and current respectively
