The APH series is a cost-effective inductive type automatic voltage regulator with output power up to 1000kVA and strong overload capability to sustain abusive loads. These features make it widely applied in motor industries, CNC machines, transportation system, production equipment , and factory for power conditioning purposes.


Employing electromagnetic inductive design, APH is different from conventional voltage regulators that it does not have graphite brush, which makes it easier to maintain. As the grid’s voltage fluctuates, APH uses the internal rotation of the motor to adjust the angle of compensation transformer to step up or step down the output voltage and stabilize the voltage to the load.


The APH series are three-phase voltage regulators with output power range from 10kVA to 1000kVA, input voltage range of -13% to + 18% (or optional -22 % to + 30%), and voltage regulation of ± 2%. The units have strong overload capability for different types of loads .
