All electronic components are selected
strictly. In addition, the main control board
is tested in high temperature environment
above seventy-two hours. It is also tested
in the vibration environment. So the
reliability can be guaranteed.
This product adopts the modularization
configuration and up-in-down-out wiring
mode. The size of the product is smaller by
adopted the advanced SMT technology in
the control board. So it can be used and
integrated easily.

according to the different load condition.
The STRLseries soft starter provides the
protective features such as Overload; Line

limit.
When Soft Starter nominal power is higher
than the actual load power, usercan modify
the actual current parameter according to
the load current. So the power of the soft

There are three pairs of anti-parallel thyristors connected to the stator of
motor. Using the electric switch feature of the thyristors, the voltage of the
motor can be controlled by changing the triggering angel of the thyristors.
The triggering angel of the thyristors is controlled by microprocessor. So
the motor canbe started softerand smooth.After the equipment is up to
full voltage, it outputs a bypass signal. User can use this signal to control
the bypass contactor to supply the motor. See figure4-1.
