Main functions:

1. Starting modes

Soft start:
This mode has the most general application. The motor is given an initial voltage setting, which is user-adjustable from 5% to 90% of the rated voltage. From the initial voltage level, the output voltage to the motor is steplessly increased during the acceleration ramp time. The acceleration ramp time is user-adjustable on touch screen 


Full voltage start:
This starting mode is used for applications requiring across the line Starting. The output voltage to the motor will reach full voltage within 1/4 Second.

2. Protection functions

Under-load:
Utilizing the under-load protection of the OSSC Smart Soft Controller, motor operation can be halted with soft stop mode if the current that is sensed is lower than user-adjustable overload current setting value. The OSSC Smart Soft Controller provides a user-adjustable under-load value from 0 to 150A.

Overload:
Utilizing the overload protection of the OSSC Smart Soft Controller, motor operation can be halted with soft stop mode if the current that is sensed is higher than the user-adjustable overload current setting value. The OSSC Smart Soft Controller provides a user-adjustable under-load value from 0 to 225A.

Protection of default phase:
Whenever the default phase is detected, the motor will be stopped with coast-to-rest mode.

Protection of current unbalance:
Whenever the current unbalance is detected (degree of unbalance >= 10%), the motor will softly stop in 60s unless the current is recovered during this period.

Protection of short circuit:
Whenever the default phase is detected, the machine will stop.

3. Parameters setting

Setup is easy by the touch screen. 

4. Communication

The AMVS series medium voltage Smart Soft starter provides a serial interface port (called RS485) as standard.

5. Soft stop

This option can be used in application that requires an extended coast-to-rest. The voltage ramp down time is user-adjustable from 0 to 225 seconds and is adjusted independently from the starting time. The load will stop when the output voltage drops to a point where the load torque is greater than the developed motor torque.

6. Coast-to-rest

To deal with some emergency, it can use coast-to-rest stop mode.

7. Parameters display by touch screen

8. Application range

Voltage range: 2.3kVAC,3.3kVAC,4.16kVAC,6.6kVAC,7.2kVAC,10kVAC,11kVAC
Current range: 40A~990A
Frequency: 50Hz 60Hz
