One control and one fan frequency conversion speed control circuit 2a
Source: InternetPublisher:笑流年 Keywords: Fan control circuit frequency conversion speed control Updated: 2020/11/01
In the figure, 1 and 2 are fault
output terminals; 6 and 7 are analog feedback current input terminals
; 6 and 8 are analog output terminals; 19 and 20 are forward
running terminals.
When the analog feedback current input changes from 4 to 20mA,
the analog output voltage changes from 0 to 10V, and the frequency
changes from 0 to 50Hz.
