Internal circuit of JYB-714 liquid level controller
Source: InternetPublisher:桂花蒸 Keywords: Liquid level controller transistor BSP Updated: 2021/05/01
The internal circuit of the JYB-714 liquid level controller (produced in Shanghai) is shown in Figure 11-7. The transistor VT3 in Figure 11-7 is used.
It integrates the temperature compensation function of the base junction to stabilize the operating point of the triode VT2.
