Recently, due to the needs of Party A, a dual-channel relay + dual-channel light control solution was developed.
The power supply part uses 220V input and uses a finished power module with parameters of 12V25W.
The relay part uses a 12V relay, and the common pin of the relay is connected to the neutral line.
The LED part uses 2 channels of PWM drive with a frequency of 5KHz. The 2 channels drive the heating and cooling channels respectively. The total maximum power of the 2 channels is 8W.
Most of the functions have been verified, and there are no problems with the circuit part. SMD prototypes are being adapted to the shell, and the finished product will be updated later.
