Automatically calculated response current values

自动计算响应电流值

 

Controlling compensation branch switchover cyclically  to prolong the service life of the compensation device

控制补偿支路循环投切，延长补偿装置使用寿命

 

Automatic setting delay output

In order to minimize the abrasion of capacitor contactor, compensation apparatus according to the change of load frequency automatically adjust the switching time interval

自动设置延时输出

为了尽量减小电容接触器的磨损，补偿仪将根据负载变化的频率自动调节投切的时间间隔

Control characteristic--Ensure that in low load will not be over compensation

控制特性-保证在低负载时不会过补偿

 

The three-phase measurement system of the SERM regulator also detects unsymmetrical loads. Thus also in unsymmetrical networks an optimum power factor correction is guaranteed. SERM控制器可测量三相电流，并检测负载不平衡。其采用特殊的算法保证在三相不平衡系统中最优功率因数补偿。可连接三相或单相电容器，可控制接触器和晶闸管开关。
