Mechanical regulator & contact SCR regulator difference 



 1 works 



 Rely on the carbon brush move on the regulating transformer to change the compensation transformer secondary winding voltage to maintain output voltage stability. Carbon brushes, contacts, and a mechanical transmission. 



 Microcomputer (MCU + PLD +12-bit high-speed AD) Intelligent detection, the output command to quickly switch to control electronic modules (IGBT or SCR) through the transformer with the frequency, phase-locked, sine wave superimposed on the compensation to maintain output voltage stability. Response speed, brushless, non-contact, non-mechanical, self-balancing three-phase voltage. 

 2 response time, mechanical adjustments 
 Fast (a power cycle 20ms) 



 3 three-phase unbalanced transfer system does not have a three-phase voltage self-balancing functions, sub-tone self-balancing three-phase voltage 
 Three-phase voltage self-balancing, all products of three-phase sub-tone 



 4 slow start to impact the conventional products (large capacity, small capacity can be added to delay the output device) 
 All products have the function of the first regulator and then output 



 5 unattended automatic boot does not have the conventional products 
 All products have an unattended automatic boot function) 



 6 sampling simulate 
 12 high-speed AD collection, collecting 64 points in a week wave, single-chip True RMS calculations. With anti-harmonic function, there is a serious harmonic interference in the power grid or load equipment, the output voltage can still remain stable, and still maintain accurate current measurement 



 Protection response to abnormal circumstances around 5S protection 
 Protection (protection Protection time) 1S after the abnormal situation 



 8 bypass function (and continuous automatic bypass) 
 9 maintenance cycle on a regular basis to maintain a maintenance-free 
 10 voltage pointer True RMS digital display 
 Current 11 pointer True RMS digital display 
 12 center voltage setting method analog potentiometers to adjust digital touch button to set the (humane) 
 13 regulator precision setting method of analog potentiometers to adjust digital touch button to set the (convenient, user-friendly) 
 14 other parameters are not set digital touch button to set (convenient, user-friendly)
