Description:
The turn-on delay is 1S to close, there is no need to use 3S delay. DC monitoring and protection, real-time protection of speakers. Turn off the speaker instantly.
All capacitors are used as soon as possible to ensure stable operation. The terminal uses the best KEFA brand industrial-grade high-current terminal. The core uses UPC1237 for protection, which is stable and reliable. The input is added with 7812 voltage stabilization to make it more stable. It is not easy to introduce noise into the power amplifier and has a longer life.
Note: The module belongs to the kit. Need to solder by yourself. If you are not a professional, please do not buy.
Features:
1 Use the best-performing UPC1237 as the core device, with functions such as start-up delay, DC protection, power failure and impact prevention
2 Using OMRIN original high-current relay as the core device is not afraid of contact ignition and oxidation
3 Use 7812 for voltage stabilization, wide power supply range, up to any range from AC12V to AC24V
4 The circuit is simple and reliable. It is very easy to make, no debugging
