24v／3V regulated power supply circuit

Published:2011/3/22 22:04:00 Author:muriel | Keyword: 24v／3V, regulated power supply

24v／3V regulated power supply circuit
The potentiometers can adjust output voltage to the rated value. Capacitor C1 makes the output AC voltage short circuit, capacitor C4 can preventsthe fuse fusing when the device is connected, and C2can inhibit the high-frequency oscillation. Technology data of the circuit: output voltage:U2=24V output current:I2≤3A input voltage:U1=29.5V~44.2V internal resistance:Rg=40mΩ output voltage variable quantity: when ambient temperatureθu=0°C~60°C, ΔU2≤10mV when output current I2=0~3A(U1=constant), ΔU2=120mV when input voltage U1=29.5~44.2V(I2=0),ΔU2=18mV (View)
