Introduction: It is a kind of contact ratio autotransformer which can adjust load voltage within rated voltage. This series of products are well designed because they adopt UK imported A brush for voltage adjusting parts. With strict quality control during production, this kind of device is very small, light, with low waveform distortion, low noise, and low temperature.

Technical parameter:
Capacity: 5\10\16\20\25\30\40\50\80\100\125\160^1500kVA
Maximum of phase of input and output:
Single phase: 220/0-250V,380V/0-430V
Three-phase: 380V/0-430(650)V
Notes: Direct output would be high voltage if not set.
