Feature:
1. Double sided plate design PCB
2. Using single-chip microcomputer to control, stable and reliable performance, strong anti-interference, and can not trigger error, the performance is superior to CD4013
3. The high voltage regulator tube provides sufficient and stable voltage, and has enough heat dissipation holes to ensure stable and reliable operation for a long time
4. The utility model has the advantages of preventing the power supply from being connected with the reverse protection diode, and the short time reverse power supply will not cause any damage to the product
5. With tact switch as a product test, the stability of the product is checked directly
6. The trigger can also be connected with an external trigger switch, and the product is matched with a connecting seat and a lead wire, so that the utility model is more convenient to use
Instructions:
1. Press the voltage version to connect the corresponding direct power supply
2. Products using pressure regulator tube (5V no regulator tube), a slight fever, is a normal phenomenon, the relay work for a long time there are normal fever phenomenon, is a normal phenomenon
3. Load power to relay load to leave a certain margin, should avoid large power (2000W) and work for a long time environment, the product life will have a certain impact
