エネルギー吸収回路は、スイッチ（電気的または機械的）が開く際に回路のインダクタンスによって生じる電圧スパイクを抑制するために使用されます。
ファン、モーター、ローラーなどの誘導負荷をオンにする際、または電源投入時に電圧スパイクを引き起こす負荷を切り替える際に再起動するすべてのShellyリレーに使用します。
RCスナバは、回路の出力とニュートラルの間に配線する必要があります。
Wired this across the relay contacts and the flickering on my shop lights vanished immediately, the voltage spikes are gone. The board is compact enough to tuck right next to the terminal block, and it’s been running cool for a week straight without any issues.
Installed this snubber across the relay contacts and the voltage spikes on my oscilloscope dropped to almost nothing. The energy absorbing circuit does exactly what it’s supposed to, and my smart home setup has been rock solid since.
My old relay kept tripping every time the compressor kicked off, so I grabbed one of these energy-absorbing circuits and wired it in. The voltage spikes are gone now, and it's been running smooth for two weeks straight. Small part, but it did exactly what it was supposed to do.
