Features
The full digital control system adopts microprocessor, fuzzy control and high current zero crossing technology.
With powerful load adaptability and electromagnetic compatibility capability, the performance is stable and reliable.
A variety of motor start and stop mode.
The number of startup times per hour is more than 2 times that of the auto-coupling cabinet. Simple operation, easy to install and use directly, "start" and "stop" two buttons, simple operation. Panel Chinese LCD display, easy to query voltage, current and other parameters.
Small size, light weight, easy to transport and install.
Compared with the autodecoupling start up, two types of type selection are added, the ratio of performance to price is high without debugging
Failure rate of direct installation and use is low, and the simple fault can be eliminated by itself. According to the fault code can be directly telephone communication solution cabinet SCR long-term online work.
Do not use AC contactors, maintenance costs reduce environmental adaptability strong Transformer capacity requirements, generally according to the rated current of 1. 5 times configuration, self-coupling should be more than 2 times.
Wide voltage range, positive and negative deviation 15% cabinet sealing structure.

Maintenance
1. Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
Brush the dust with clean and dry brush.
Remove dust with compressed air machine.
2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
(1) Blow it with a hair dryer or electric stove.
(2) Bring it to power distribution room for dehumidification.
3. Regularly check components' intact. Whether it can work properly.
4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
Before maintenance checking, it has to cut off all power in the line side of soft starter.
