This product is a low-voltage fully intelligent built-in bypass motor soft starter. In addition to the universal soft starter function, this series also has a solution for implementing load application scenarios, which is powerful in terms of functionality.
Technical Features:
1. Communication expansion card
It can be equipped with a built-in Profibus communication expansion card.
2. External keyboard+large screen
The keyboard can be quickly plugged in and out to meet the needs of remote operation.
3. Motor preheating
In low-temperature environments, heat the motor before operation without the need for external heating equipment.
4. More comprehensive motor protection function
Overvoltage protection, undervoltage protection, overcurrent protection, overload protection, locked rotor protection, bypass fault, thyristor fault, three-phase current imbalance, motor overheating protection, etc.
5. Pump control function
Unique start and stop control for pump loads. The pump starting function reduces the starting current of pump loads; The pump stop function can reduce the water hammer effect.
6. Pump cleaning function
Automatically clean up the sediment inside the pump to prevent malfunctions such as overcurrent and overload caused by blockage.
7. Fan braking function
Power braking can quickly stop the running load; Static braking can cause the load running under external force to come to a stop.
8. Low speed operation function
It has the function of low-speed forward and low-speed reverse operation, and can adjust the direction of load operation at low speed before the motor starts normally.
9. Wide power supply voltage range
Satisfy the universal input voltage of 220V-500V main power supply.
