Frequency sensitive rheostat manual and automatic one-way starting circuit
Source: InternetPublisher:笑流年 Keywords: Rheostat starting circuit BSP Updated: 2021/02/02
The circuit is shown in Figure 3-164. This circuit can be used in both manual and automatic
modes.
During the startup process, the normally closed contact of KA short-circuit the heating element of the thermal relay FR to prevent
the thermal relay from malfunctioning due to a long startup time and affecting the startup.
