Item details
DIGISTART STV 1312
The DIGISTART is a fully digitized soft starter with an 8-bit microprocessor, which can be used with all three-phase asynchronous squirrel-cage motors.
It ensures a gradual start-up of the motor with:
- reduced current consumption during start-up,
- shock-free acceleration by controlling the current drawn by the motor.
After start-up, the DIGISTART performs the additional functions described below.
Functional description
The DIGISTART STV 1312 consists of:
- a power module,
