MG3 Soft Starter Water Pump Soft Starter
Product main features
Perfect pump control
By means of special algorithms for starting and stopping pumps and
fans, e.g. quadratic torque control, this is an effective way of
controlling the starting and stopping of pumps and fans.
Compact design
Compact and attractive design saves installation space.
Stop function
Perfect pump shutdown function, effectively solving the "water
hammer effect" and alleviating mechanical shock, increasing the
service life of the equipment.
Modularized design
A variety of expandable function modules, to meet the individual
needs of customers, easy to upgrade and maintain the equipment.
Communication function
Optional ModbusRtu communication protocol is easy to realize group
control.

motor and soft starter will not be damaged in case of malfunction
and misoperation.
High speed
Zero operation response time, fast and accurate.
Three-proof technology
The internal control boards all adopt the harsh three-proof paint
process, which can effectively resist water, dust, humidity, salt
spray and corrosive gases.
