The soft start time is adjustable for 30 seconds (time rise refers to 0-380V).
The initial Voltage is adjustable from 150-250V to the rated Voltage (380V)
There are two ways to use
1. When the switch is closed, the main power supply is energized and the soft start starts.
2. Use switch to control, close soft start to start, open stop
The soft start module now has three programs:
1. TSR-40WA-R1 has soft start without soft stop
2. TSR-40WA-R2 has a soft start and a soft stop (as much as V start, as many V stop)
3. TSR-40WA-R3 has soft start and soft stop (soft stop to 0)
Note: 1. No voltage can be applied to the switch
2. The default R1 is not required
3. Please use this module with heat sink
Models are: 1KW, 2KW, 4KW, 6KW, 8KW, 10KW, 12KW, 15KW, 20KW
Aluminum bottom: TsR-10WA-R, TSR-20WA-R, TSR-40WA-R
Copper bottom: TsR-40WA-R, TSR-60WA-R, TSR-80WA-R, TSR-100WA-R, TSR-120WA-R,
TSR-150WA-R, TSR-200WA-R
When the starting potentiometer is adjusted to half, the starting point is
200V, and the longest time of the soft starting potentiometer is 30
seconds corresponding to the full 380V
For example: when all is adjusted to the minimum: the starting voltage of 150V takes 0 seconds
When fully adjusted to half: start at 200V, soft start time is about 7 seconds
When fully adjusted to the maximum: the initial voltage from 250Vv to 380V takes 10 seconds
General recommendation for selection margin: TSR-10WA-R for 1KW, TSR-80WA-R for 8KW
motor Recommended radiator: radiator S1 for below 4KW, radiator S1+F80 for below 8KW,
Radiator DS1+F90 for under 12KW, radiator S2-120+F120 for under 20KW
