Soft Starter operating modes

When the motor load light, soft starter in the select power-saving state, PF switch hot to the y position, in the presence of current feedback, automatically lowering motor voltage soft starter. Reduces the motor current of excitation. Improving the power factor of the motor (COS l). (Homemade soft starters do not have this feature) unable to implement this feature in a contactor bypass State. TPF switch supplies energy-saving function of two kinds of reaction time, normal, slow. Energy-saving operating modes: automatic operation. (Normal, slow speed two speeds) no-load energy saving 40%, load 5% energy.
