Product Description

General
The main function of the built-in bypass soft starter is to reduce the pressure on the motor during startup by controlling the voltage and current changes, thereby increasing startup ef-  ficiency and extending the motor's lifespan.
The built-in bypass soft starter typically includes  bypass contactors and control power supplies, enabling a smooth transition to bypass mode during startup to prevent the motor from experiencing excessive current and voltage shocks.

Operating conditions
1.  Incoming line power supply: AC 380V ± 5% 50/60 Hz
2.  Power supply is applicable: mouse cage three-phase asynchronous motor
3.  Cooling mode: forced air cooling
4.  App licable temperature: -10°C ~ ± 40°C ,1°C,2%, + 50°C
5.  App licable humidity: 90% without frost
6.  Place of use: No corrosive gas without conductive dust indoor is well ventilated
7.  Elevation vibration: The altitude is below 3000 meters, and the vibration power device is below 0.5G

Please refer to 485 communication protocol for details

(1). Contact input terminal
a.  Use external terminals to control the start and stop fuctions of the soft starter. Please set the start stop control to l (keyboard+terminal).
b.  If remote control requirements are required, it is recommended to use the (second line) control method.
c.  The input terminal and common terinal of the contact signal are generally in an 0N/0rF action, which can cause interference in soft start- ersmotors, and wiring, therefore wiring is necessaryPlease use shielded wires for cables that are as short as possible (less than 20m).
d.  The wiring of control terminals must be as far away as posible from the wiring of the main cireuit. 0therwise, it may cause erroneous actionsdue to interference.
