the main circuit adopts three-in and three-out wiring modes, built-in bypass contactor and built-in three-phase current transformer to detect three-phase electricity in real time.
Flow and load parameters; built-in I2t overload protection function, after the start of the start process (built-in contactor pull-in), overload protection
Function works; with microcomputer protection such as phase loss, phase current imbalance, thyristor overheating, overcurrent, overload, and leakage detection
Features;
the **-bit advanced single-chip microcomputer is used as the control core, and the keyboard and LCD display various parameters and parameters are convenient to set up.
Rich detection and perfect protection functions;
Communication function: equipped with RS**5 communication interface, embedded Modbus communication protocol, convenient to configure connection;
Multiple start modes: Voltage ramp linear start (with current limiting characteristics), voltage ramp nonlinear start (with current limit
()), current ramp linear start, current ramp nonlinear start, current limit start, pulse kick start, etc.
Analog signal control: user can ***0mA or ***0mA standard signal and can simulate on the operation panel
the upper and lower limits of the quantity are set to realize the start and stop control and alarm of the motor. Data can also be processed via a soft starter (pressure, temperature
Transmission of degrees, flows, etc.). with ***0mA or ***0mA standard analog signal output function.
the and output adopt photoelectric isolation technology, and the control board adopts advanced SMT chip technology, which has strong anti-interference ability and safety.
High energy
Two-parameter setting: the soft starter has control parameters for setting two sets of different power motors at the same time, which can control two different powers.
the start of the motor.
A variety of parking methods: free parking, brake parking, programmable soft parking, soft parking + brake parking.
Dynamic fault memory: up to *5 faults can be recorded, making it easy to find the cause of the fault.
