quality Distribution boxThe purpose of the Y-Δ (star-delta)
control box water pump control box is to reduce the starting
current and reduce the damage to the power grid and common
equipment.The condition that the star-delta start is required is
that when the load is light, the load is heavy when starting, the
load has no strict requirements on the starting torque of the
motor, and the starting current of the motor is limited. The motor
meets the 380V/Δ wiring condition to adopt the star-delta starting
method.The method is: when the motor starts, the motor is connected
to the star type wiring, and when the motor starts successfully,
the motor is changed into a triangle type wiring.Since the motor
starting current is proportional to the power supply voltage, the
starting current provided by the grid is only 1/3 of the full
voltage starting current, but the starting torque is only 1/3 of
the full voltage starting torque.The star-delta startup, which is a
buck start, is achieved at the expense of power in exchange for
lowering the startup current.Star-delta control box for water pump

quality Distribution boxThe star-delta start-up circuit
reduces the starting current and reduces the damage to the grid and
common equipment.Low manufacturing cost and long service life, but
the starting torque is fixed at 1/3.The star-delta start control
box has overload, short circuit, phase loss protection and pump
body leakage.Motor over temperature and leakage and other
protection functions and complete status display, with single pump
and multi-pump control mode, a variety of active and standby pump
switching methods and various starting
methods.Star-delta control box water pump control
box useThe star-delta start-up control box can be widely used
in industrial and agricultural production and automatic control of
water supply, drainage, fire protection, sprinkler pipe network
pressurization and HVAC hot and cold water circulation in various
buildings.Star-delta control box water pump control
