In the circuit the current peak value is a certain value gothrough the limit of the resistor R4, and the output of DC current value is limited by the diodes. The former can adjust by potentiometer R8, the latter can beadjusted by potentiometer R2.
The main technical data: output voltage:U2=12V output current:I2=5A input voltage:U1=17.5V~26.3V internal resistance:R2≤40mΩ output voltage variable quantity: When output voltage U1=17.5V~26.3V, ΔU2=10mV; when output current I2=0A~5A(U1=constant), ΔU2=170mV; ambient temperature θu=0°C~60°C, ΔU2=24mV.
