Marine Transformer QZB

Auto former step-down start is to use auto transformer lower supply voltage, to reduce the starting current, at the same time also can be changed by selecting different tap auto transformer starting current and achieve the purpose of changing starting torque, this way of starting at the time of starting have less effect on the power supply voltage, less impact on the mechanical, when starting motor starting time is shorter, usually used for main circuit ac 50 HZ or 60 HZ, rated voltage 1200 v and below the auto voltage reducing starter kit use QZB series step-down starting auto transformer for frequent starting, not stop. QZB series step-down starting auto transformer look neat and easy, small volume, light weight, reliable operation, by users praise.
