CC20038B-FA Fast Switch Speed No Noise Spark High Reliability LED Display Three Phase AC Contactless Contactor

 

 

CC20038B-FA Fast Switch Speed No Noise Spark High Reliability LED Display Three Phase AC Contactless Contactor is a new contactless switch device which combines power electronics technology with microelectronics technology. It has the advantages of fast switching speed, no noise, no spark, shock resistance and long life. It has the functions of over temperature alarm, over temperature protection, SCR fault detection, no ground or zero line phase missing protection, protection action buzzer alarm and so on. The high quality thyristor chip and imported chip are used in the selection of power device strictly. It has high VRRM value of VDRM and built-in resistive and capacitive protection to ensure the reliability of the product. The working principle is the same as the traditional AC contactor, and it can replace the soft starting of the motor when the starting requirement of the motor is not high, so it is the replacement product of the traditional AC contactor.

 

Feature

 

1. Built-in auxiliary contacts (two pairs of open and close contacts), can be customized overtemperature alarm, phase deficiency protection, SCR fault detection

2. Traditional relay working mode

3. The power device uses imported chip, vacuum nitrogen protection welding, reliable performance, longer life.

4.Rated load current 25-200A

5. Rated load voltage range 50-480 VAC

6. 220 / 380 VAC AC control, 12-32 VDC DC control

7. 2 LED indicator lights, 3 alarm signal lights

8. Protection action can be customized buzzer alarm function

The control, trigger, detection, protection circuit and AC main circuit of AC contactor are designed in full isolation structure. High quality thyristor chip is used in power device, which has high blocking ability and good overload ability. The main circuit substrate adopts DBC ceramic copper clad plate, which has good overcurrent capacity and excellent heat dissipation. The current structure design is rigorous, the main circuit adopts vacuum nitrogen welding technology to ensure the product quality is excellent. The circuit of control, trigger, detection and protection adopts mature and reliable design scheme, and has multiple input control mode, all of which are designed with constant current source. It has perfect alarm, protection function, input and output photoelectric isolation, zero crossing conduction of main circuit to reduce the impact to the load, and the internal power device is effectively protected by internal resistive absorption and capacitive absorption.

Ac contactless contactor is widely used in direct starting control and electric heating control of three-phase motor with small capacity. Suitable for steel, chemical, machine tools, coal, electric heating control and other production environment, frequent switching, flammable and explosive occasions, is a traditional contactor replacement products.

1. Three phase power supply switch, yellow indicator light

2. Control signal 3, green indicator light

3. Bottom plate overtemperature 80 °C alarm, red overtemperature indicator light bright, temperature drop treatment should be done. If the bottom plate temperature exceeds the limit temperature 85 °C (customizable), automatic protection, cutting off the main circuit.

4. Fault: three phase power supply phase, protection action, block the main circuit at the same time red fault indicator light, any one phase silicon controlled short circuit, The thyristor fault alarm lamp is on after closing.

Note:

1. Type selection correlation: inductive load (AC motor, AC electromagnet, inductor coil, transformer, etc.), capacitive load (electric capacitor compensator), resistive load (electric heating incandescent lamp, etc.) actual current should be ≤ rated load current, User according to the actual situation left sufficient margin. 2. Ac contactless contactor, single-phase, three-phase solid state relay is strictly forbidden to direct connection to forward and reverse rotation or star triangle control, if you want to be used in the above control, please use with practical relay.

3.Switch original upgrade: replace the traditional switch devices, please connect correctly, especially pay attention to the control signal type, input parameters, the main loop input and output back, wrong connection, to prevent improper wiring caused permanent damage.

4. Heat dissipation: contactless contactor, solid state relay series products should be equipped with radiator, radiator surface should be smooth and smooth, it and radiator should be smeared with heat conductive silicone grease, four-angle screw installation stress should be equal. If the current is larger than 5A, the radiator with fan should be used, the installation should be far away from the heat source, strong electromagnetic interference, RF interference environment, such as environmental temperature should be reduced to use.

5.Over-voltage, overcurrent protection: when the load is inductive or capacitive, it may produce a momentary voltage greater than the SCR can withstand and thus be broken down. Therefore, there is RC protection inside the product to prevent the surge voltage from damaging the SCR, at the same time, the additional varistor can be added to prevent the overvoltage, the area of the additional varistor determines the absorption power, the thickness determines the protection voltage value, and the user can choose according to the actual situation. Overcurrent and load short circuit are the main causes of permanent damage to the internal SCR, so appropriate air switches and fast fuses should be installed.

6. Installation, maintenance instructions: the installation should be good heat dissipation, wiring should be reliable, if the connection loose, will cause too large wiring resistance, so that the contact point current density increase, heating increase, may damage the power device. Because contactless contactor, solid state relay, forward and reverse turn module, voltage regulation module of power device exist 5-10mA leakage current, RC resistance and capacitance absorption will also produce leakage current, so please disconnect the circuit breaker during maintenance.
