the default delivery of this product is R1, if you need R2, R3 please leave a message when you place an order, thank you.

Note: The three-phase motor soft start module can work for a long time without switching the contactor. Selection: 20A for 2KW, 40A for 3-4KW, 60A for 5-6KW, 80A for 7-8KW, 100A for 8-10KW , 11-15KW with 150A, 20KW with 200A, the greater the motor power, the heat sink must also be equipped with large, this product has been sold out thousands of pieces, only a few places motor is not suitable.

Applicable place Can be widely used in fans, pumps, belt conveyors, ball mills, conveyors and compressors and other loads. It is an ideal replacement product for replacing the traditional star/delta conversion, auto-coupling buck, magnetic control step-down, inverter and other step-down starting devices, safe and reliable. Suitable for three phases: 380V, compatible: 50-60HZ

Three-phase motor soft start module

The soft start time is adjustable for 30 seconds (time rise refers to 0-380V).
Starting voltage can be adjusted from 150V-250V to rated voltage (380V)

There are two ways to use it:

1. When the switch is closed, the main power supply is energized. The soft start begins.
2, use the switch to control, close the soft start, disconnect

The soft start module now has three programs:

1.TSR-40WA-R1 has soft start and no soft stop
2. TSR-40WA-R2 has soft start and soft stop (how many V starts from how many V starts)
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 delivery of this product is R1, if you need R2, R3 please leave a message when you place an order, thank you.
         3. Please use this radiator for this module.

Uses: pumps, fans, aerial vehicles, ordinary motor soft start, replace the soft start of the inverter, replace the soft start of the star triangle, etc., the wiring is super simple, no need to connect the bypass contactor, powerful.

When the starting potentiometer is halfway up, it starts at 200V.
The soft potentiometer lasts for a maximum of 30 seconds and corresponds to a full 380V.
For example: when the whole process is adjusted to the minimum: the starting voltage is 150V and it takes 0 seconds.
            When the whole process is adjusted to half: start 200V, soft start time is about 7 seconds.
            When the whole process is adjusted to the maximum: the starting voltage is 250V to 380V for 10 seconds.
Selection allowance is generally recommended: TSR-10WA-R for 1KW, TSR-80WA-R for 8KW motor
Radiator recommendation: radiator S1 below 4KW, radiator S1+F80 below 8KW, radiator DS1+F90 below 12KW, radiator S2-120+F120 below 20KW

The following are the parameters of the three-phase motor soft start module:

Three-phase motor soft start module features, new products.
1.No signal, it can be softened directly, soft start time (0-30 seconds) can be preset. Starting voltage (150-250V) can be preset
2.thyristor output, can be used for three-phase star-delta connection
3.Use a suitable radiator when using, and add forced air cooling if necessary.
4.This product is a multi-function power integration module that encapsulates the main circuit of the thyristor and the phase shift trigger control circuit.
5.Flame-retardant engineering plastic shell, copper base plate, high temperature welding, strong transient overload capability
6.Main use fan speed control, torque motor speed regulation, ordinary motor soft start, etc.
