Published:2011/4/18 2:44:00 Author:muriel | Keyword: 12V/5A , regulated power supply

12V/5A regulated power supply circuit
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.

Adjustable constant temperature controller circuit diagram

Published:2011/4/19 4:36:00 Author:Nicole | Keyword: constant temperature controller

The adjustable constant temperature controller circuit is asbelow. REF01E provides TMP17 with 10V high steady power supply, it can obtain a voltage singal from resistor R1, the voltage is in direct proportion t0 the measured temperature t. AD790 is a voltage comparator. If t represents the measured temperature and to represents the set value, when t>t0, the output of constant temperature controller is low level, when t<t0, it is high level. The value of to can be adjusted by potentiometer PR. C1 is denoising capacitance, C2 is accelerate capacitance. The output terminal of temperature control circuit controls the electric heating device by means of all kinds of actuators, then to achieve temperature control. (View)
