Auto & Manual Mode Water Pump Controller ,Available For Booster & Water Transfer & Sewage Lifting ,Output Power From 0.75-250kw ,Metal Housing

1. Hunan Leading Intelligence Pump Controller general introduction
Intelligence Pump Controller adopt the digital control chip, With Automatic and manual two working mode can be selected with 6 Applications and By measuring working current to activate protection function.

The unit features an advanced microprocessor controller bonded to the pcb board within the enclosure. Heavy contactors and current overload devices support three phase 380VAC pumps with Start/Run motor windings and an average load current of up to 500 Amps. An integrated dry contact point ensures protection against water leakage faults(optional)
A number of alarm conditions will be declared and recorded where normal operating parameters have been exceeded.
