It can be used in conjunction with various automated instruments without interference to the instrument, and can also be manually controlled by an external potentiometer. Such as DC motor speed regulation, voltage regulation, charging, etc. Users can connect ordinary thyristor or bidirectional thyristor, mainly used for three-phase pure resistive load, three-phase inductive load or three-phase transformer primary control, such as silicon carbon rod, silicon molybdenum rod, resistance wire, etc., can also be used for Three-phase full-bridge full-control rectifier has the advantages of reliable triggering, stable operation and flexible use.Scope of application1.

Motor speed regulation: torque motor speed regulation (ordinary motors can't regulate speed)Main technical parameters of three-phase thyristor phase-shift trigger board1. High-performance imported single-chip microcomputer is used as control, with high three-phase balance, good waveform symmetry, small DC component, good linearization, high control precision and stable operation.2. Wide working voltage. The input working line voltage can be as low as 4% of the rated voltage, and its control accuracy is basically unchanged.3. High triggering power, can directly trigger 3000A thyristor (trigger current below 300mA)4. Self-contained bias power supply, 200V, 380V optional (default built-in 380V), simple wiring, easy maintenance. Dimensions: 100mm(L)*83mm(W)*50mm(H)5. Various control signal input: DC4-20mA, DC1-5V, DC0-10V, 10K potentiometer6. With soft start adjustable in 60 seconds, the maximum voltage limit is adjustable.7. Compatible: 45-65Hz8. The revised design is novel and , no external synchronous transformer and no phase sequence restrictions9. It can be applied to three-phase 6-silicon anti-parallel voltage regulation, or three-phase 6-silicon full-controlled rectification, and a dedicated three-phase half-controlled rectifier board10. The main circuit and the control circuit are fully isolated, safe and reliable.<;5%) and large trigger current. It is suitable for any thyristor trigger and can be realized for any load. Stepless adjustment. It can realize AC and DC motors, soft start and speed regulation. For transformer primary voltage regulation, welding machine, temperature control, excitation, electroplating, water treatment, torque motor speed regulation, etc.Troubleshooting1. The power indicator light is not on, it may be that there is no power supply and the chip is not working. The working light is off, and there may be no signal source coming in.2. There is no output from the trigger G pin, first confirm whether the load is connected, and you can't test it without the load.3. The output of analog signal (4-20MA, 0-10V, 1-5V) is not adjustable, first confirm whether the load is connected, it cannot be tested without the load, you can first use the potentiometer: 10K, manual debugging4. There is no output from the thyristor. When confirming that other lines are connected well, check KA+KB+KC+, which is the 380V limit detection line. The multimeter measures 380V, if not, it is reversed.Model Number : TSCR-CPhase : Three Phase
