Common faults and solutions of soft starters(1)
1. Instantaneous stop: The cause of this fault is generally caused by the wrong wiring of the external control. If the user does not particularly

What if there is no suitable soft starter, can a high-power soft starter bring a small motor? Generally, the specifications of low-voltage motor soft start
With the development of modern science and technology to today’s level, soft starters, as one of the most common products in the electronics industry, also
Soft starter input power failure 1. Check whether the input power is normal step by step. First, check whether the input power of the soft
The contactor connected in parallel with the soft starter is called a bypass contactor, because the long-term use of the soft starter to start will
A controllable reactor is connected in series in the stator circuit of the three-phase asynchronous motor. During the start and stop of the asynchronous motor,
For the starting of the water resistance cabinet, the following issues should be paid attention to in normal operation: 1.Before closing and starting, check whether
Main voltage range, main current range, control voltage, soft start time, soft stop time, initial voltage. Motor soft start is to achieve smooth start of
When a high-power motor starts, the starting current is large, which will cause serious fluctuations in the grid voltage. In order to solve this problem,
The soft start is mainly composed of three pairs of anti-parallel thyristor voltage regulating circuits connected in series between the power supply and the controlled
