Circuit diagram of low voltage disconnection alarm
Source: InternetPublisher:难得正经 Keywords: Alarm alarm control low voltage disconnection Updated: 2021/10/23
The circuit working principle of the device is shown in the figure. When the wire mesh Fe is intact, the ① and ② pins of LSE are in collusion, and its ④ pin outputs high level, the transistor VT is cut off, the relay J is released, and the alarm does not work.
