    7.5KW Soft Starters Details

    Tips: Motor soft starter model selection
    In actual working should consider the specific product features and technical parameters and product reliability, and according to the actual usage to choose the soft starter. Here it is necessary to differentiate that motor is frequent start or infrequent start. For the soft starter, in general, if the motor start interval time does not exceed 2 minutes, and 30 times per hour, can be identified as infrequent start. Less than 2 minutes should be considered as frequent start. Fan and pump load generally belong to infrequent start. Mechanical transmission type like belt machine, grinding mill, and others can be considered as infrequent start. If the motor is starter, or electromotor that is equipped for the large machinery equipment needing reversible function, mostly belongs to frequent start.
    Choosing a soft starter for frequent working place should according to the motor starting current. Normal soft starter silicone controlled rectifier current is 2.5 times of motor rated current. Limit the maximum motor starting current is 4.5 times of the rated current. In the infrequent operation can take full advantage of SCR short-term overload capacity. In the conditions of frequent starting, should select increasing the soft starter capacity, according to the different of frequency take 1.2 to 1.5 times of the capacity. At the same time, due to the SCR frequent working and generating a lot of heat, the soft starter must be equipped with mechanical air-cooled to dissipate heat. It is best to put a mechanical air-cooled soft start device for each switchgear, and the switchgear should also be set with mechanical ventilation.

    Soft Starter Works with a Bypass Contactor

    Soft starter works with a bypass contactor saving energy by eliminating thyristor losses during the run. The bypass contactor shunts the current flowing through the soft starter switch circuit to reduce heat accumulation in the soft starter power electronics during motor operation. This provides maximum efficiency and prolongs the life of soft-start switching components because they only work during the start and stop cycles of the motor.

    What terminals I need to hook into for a start/stop switch on this drive?
    Hello,  I'm wondering what terminals I need to hook into for a start/stop switch on this drive.  I watched the YouTube video but I don't have that 3 position switch. All I have is a start/stop button or an on/off switch. Thanks

    Please short-circuit terminals 7 and 10 of the soft starter to lead out a wire, short-circuit terminals 8 and 9 to lead out a wire, and connect these two wires to your switch or button.
    When these two wires are closed, the machine will start, and when these two wires are disconnected, the machine will stop.
    One thing I found weird
    I just installed this soft starter. One thing I found weird as well (which sucks) is I ran power through the by pass contacts (1

    1. The bypass contact (1&2) of the soft starter is used to control the coil of the bypass contactor. The rated capacity of the bypass contact (1&2) is only 250V/5A.  The coil voltage of the bypass contactor is also required to be lower than 250V.
    2. Suppose your grid voltage is three-phase 380V, and the bypass contactor coil is 220V, then the voltage of one live wire and one natural wire in the grid (L+N=220V).  You can connect a live wire L in the grid to a terminal A1 of the contactor coil through the bypass contact (1&2), and connect the other end A2 of the contactor coil to the natural wire N.
    3. If the soft starter has burned out, you need to buy another new one, please refer to the link:
    Could you please provide your motor nameplate to us for further confirmation?
    Can I start your 50hp soft starter remotely with a 120 volt switch?
    Can I start your 50hp soft starter remotely with a 120 volt switch?

    Yes, sure. This soft starter remote control can be done via (wires + switch), therefore, you can use 120V to control a relay, and then control the start and stop of the soft starter through the contact switch of the relay. It is a very simple control method.
    Good product, meets my need
    This 15A soft starter is applied to my 25A motor. I can handle the unit with no trouble. All the parameters are set on the panel by knob potentiometers and dial switch, that is intuitive and accurate. I feel my motor works really much better than before.
