Appendix:about power supply
An isolated power supply must be used. At the same time, the AC rectifier bridge and transformer
■
should avoid direct contact with the module, and try not to make the transformer and rectifier face
the module. The shielding layer can be staggered or added.
The power supply ripple should be less than 50mV as far as possible to avoid spikes in the power supply.
■
Do not add devices such as anti-reverse diodes in the DC power supply chain. Adding any device
■
to the DC power supply chain will increase the power supply noise and cause false alarms.
The power drive current should not be less than the normal operating current of the module.
