Hardware design description
1) Input power supply requirements
| minimum （RMS） | typical case （RMS） | maximum （RMS） | unit | |
| input voltage | 3.0 | 3.3 | 3.6 | V |
| input currenton | 29 | 129 | 290 | mA |
The motherboard is close to the 3.3V input end of the module. At least one 10uF and 0.1uF energy storage capacitor is placed to the ground to reduce the power supply ripple and the peak value of ripple is less than 100mVpp.
- Module 3.3V is connected to other 3.3V on the motherboard at 600R/100MHz@1A.
- Module 3.3V circuit ensures an average current of 300mA and above current demand, and the
maximum transient peak current can reach about 1A when the full power PLC signal output.
2) PLC module docking design
In the product design end, the safety protection design of L/N line and PLC + signal coupling design are suggested to refer to the following circuit diagram.
Note: The T1 transformer in the diagram is a 1:1 transformer. The recommended safety capacitor (C1) should be 10nF. The semiconductor discharge tube (D1) is mandatory. After the PLC signal input point on the L/N line is connected to the surge protection circuit, the varistor's charging capacitance should be less than 600pF. Two differential-mode inductors (L1/L2) should be connected in series after the PLC signal to isolate it from the main power load, with recommended inductance values of 50-100μH.
