? ? ? ? ?The single-phase thyristor trigger board is composed of the integrated trigger circuit, operational amplifier, pulse transformer and other units produced by our company. Isolation of input and output, it can be used with various automatic instruments without interference to the instrument, and it can also be manually controlled by an external potentiometer. Such as AC and DC motor speed regulation, voltage regulation, charging, etc. Mainly used for single-phase pure resistive load, single-phase inductive load or primary side control of transformer, such as silicon carbide rod, silicon molybdenum rod, resistance wire, etc., can also be used for single-phase or two-phase full-bridge semi-controlled rectification, with reliable triggering , the work is stable and the use of flexible advantages.

Easy Troubleshooting
1. If the power indicator is not on, the power supply may not be supplied. Check that L1 and L2 are the power supply and the synchronization signal line. The output indicator is not on. Check whether the input signal is supplied.
2. There is no output from the trigger G pin, first confirm whether it is connected to the load, you can't test it without the load, this board is based on the principle of phase shifting, if there is no loop, it will not work. Load debugging.
3. The output is not adjustable with the analog signal (4-20MA, 0-10V, 1-5V), first confirm whether the load is connected, you can't test it without the load, you can use the 10K potentiometer first, manually debug it, and see if it is normal Is it an analog signal source problem?
4. There is no output from the thyristor. Make sure other lines are connected well. Check whether K1, G1, K2, G2, L1, L2 are connected incorrectly. Note that G and K cannot be reversed. L1 and L2 are synchronous detection lines and Power supply, regardless of zero fire.
