    Three-phase Soft-starter for Air Conditioner

    Product description:

    TL-ASSU380 type air conditioner soft-starter is an embedded air conditioner controller based on our independent research and development. Advanced single chip microcomputer as the micro-controller technology is adopted to intelligently regulate startup voltage and current of compressor with the effective reduction of startup transient current and power of compressor, so as to protect the compressor, increase its service life, and minimize the impact on the power system resulted from the high-power air conditioners startup.

    Embedded style system design is used for TL-ASSU380 type air conditioner soft-starter with the following features: small in size, light in weight, strong impact and shock resistances, high reliability, long service life, and easy installation. Internal electronic components are all imported industrial products to meet requirements of any complicated work environment with stable performance.

    Scope of application:

    Three-phase air conditioners

    Three-phase motors

    Technical features:

    1. Limitation of starting current;
    2. Elimination of inrush current and voltage;Heat production decreases due to bypass switch module;
    3. Moment control to realize the smooth start and stop of the compressor
    4. Alleviation of vibration and mechanical deterioration;
    5. Discharge of impact and gear stress on startup;
    6. Easy wiring and installation, and equipment downtime reduction;
    7. High reliability and long service life.

    Electrical diameters:

    1. Available power: 380V/7.5KW/3PH, 190V/4KW/3PH (less than 20A current);
    2. Operation voltage: 187~266VAC;
    3. Rated operational current: 20A;
    4. Startup current: 60A/2.5S (triple rated operational current);
    5. Inrush current: 400A/20mS;
    6. Current dissipation: ≤22mA;
    7. Power consumption: less than 5W;
    8. Soft-start time: ≤2.5 Second;
    9. Run-time: 45,000 hours (within the rated operating temperature range);
    10. 10. Start count: 100,000 times (more than 3 minutes start interval under normal circumstance);

    Environmental parameters:

    1. Operating temperature range: -20~+65°C;

    2. Flame retardant property: insulating material with flame retardant property;

    3. Relative humidity: 0 – 95%;

    4. Impact resistance: 200m/s2 11ms;

    5. Shock resistance: 10-55mm (double amplitude 1.5mm);

    6. Rust-resisting property: every metal parts can undertake at least 24 hours salt spray


    Dimension and weight:

    1. Weight: about 400 grams;
    2. Dimension: L*W*H (152.4mm*101.6mm*40mm);

    Components introduction:

    1. Main wiring terminals:

    250# insert is adopted for the connection of main wire terminals, i.e. A_IN, B_IN, C_IN, N_IN is three-phase and four- line AC input, A_OUT, B_OUT, C_OUT is the corresponding soft-start output to link with the three-phase compressor.

    1. Control wire terminals:

    Row connector is adopted for the connection of control wire terminals in an easy and reliable method. Control soft entry terminals own input control terminal start and protection, and power supply output of soft-starter. Output terminals have main and broken circuits control terminal and by pass control terminal. The external bypass mode is used to realize more stability.

    1. Pushwheel switch:

    Soft-starter owns the flexible starting time and starting initial voltage regulations, to meet the different requirements of payload types.

    1. Selected keyboard connectors:

    One 6P (2.54mm) connector on the top has total 4 lines analog input terminal to control the parameters of initial output voltage and starting time, and another 6P (2.54mm) input terminal is a SPI output terminal to display the operation parameters values.

    1. Transformer and relay:

    Blue transformer is an industrial grade safety isolating transformer with encapsulating material, which has characteristics of more secure usage and better flame retarding. Two relays on the right are used for output control terminal, among them, middle one is cut-out control, and right one is bypass control.
