IC693ACC350

IC693ACC350暖通空調(diào)負荷（壓縮機、風扇、氣體閥等）關斷期間，信號繼電器的觸點斷開。當觸點打開時，整流橋的端子看到HVAC變壓器的電壓為24VAC，并將交流電源轉(zhuǎn)為直流電源，如先前所述。由此得到的直流電壓被用于驅(qū)動恒溫器或子電路。

暖通空調(diào)負荷導通期間，信號繼電器的觸點閉合。當觸點關閉時，跨過整流橋端子的電壓降到零。這樣無需將24VAC用作電源，因此恒溫器的電池電源控制電路。操作機電繼電器所需電流的范圍從幾十到幾百毫安不等，它可對電池壽命產(chǎn)生顯著影響。

如果有種方法無需要使用恒溫器的電池即可驅(qū)動繼電器，情況將會怎樣？電池壽命會增加，更換頻率將進一步降低。一種方法是在暖通空調(diào)負荷導通期間（信號繼電器觸點閉合），短暫打開繼電器并為控制系統(tǒng)充電。相比功率繼電器的關斷時間，充電期間所需時間需要非常短，這樣可激勵功率繼電器及其相應負荷。不幸的是，機電（信號）繼電器由于其開關速度限制不太可能實現(xiàn)這一目標。觸點移至期望位置花費的時間處在毫秒范圍內(nèi)，并將中斷HVAC負荷運轉(zhuǎn)。
