How To Make A Bench Power Supply With Lm338 0 35v 5a Youtube Hi, in this video i'll show you how to make an adjustable power supply. thanks for watching and don't forget to like, share and subscribe for more!. The lm138 lm238 lm338 are adjustable 3 terminal positive voltage regulators capable of supplying in excess of 5a over a 1.2v to 32v output range. they are exceptionally easy to use and require only 2 resistors to set the output voltage. the careful circuit design has resulted in outstanding load and line regulation comparable to many commercial.
Lm338 Adjustable Power Supply 5a Connect the in pin of the lm338 to the input voltage source. connect the out pin to the circuit requiring regulated voltage. use the adj pin to adjust the output voltage. this can be done by connecting a resistor between the adj pin and the out pin. add capacitors for stability and noise reduction. Connect the input power supply within the specified range 1.5 v to 35v to ensure proper functioning of the regulator. testing: power up the circuit and measure the output voltage using a multimeter. adjust rv1 and observe changes in the output voltage. ensure the regulated output falls within the desired range. Introduction to the lm338 adjustable voltage regulator. the lm338 is a three terminal adjustable positive voltage regulator designed to supply more than 5a of load current with an output voltage adjustable over a 1.2v to 32v range. it offers several features that make it an attractive choice for various power supply applications:. 15 amp, variable voltage regulator circuit. the ic lm 338 alone is specified for handling a maximum of 5 amp of current, however if the ic is needed to handle higher currents, in the region of 15 amps, it can well be modified to produce that much of current with the appropriate modifications as shown below. the circuit utilizes three ic lm338.
Lm338 Circuits Projects Wiring Draw Introduction to the lm338 adjustable voltage regulator. the lm338 is a three terminal adjustable positive voltage regulator designed to supply more than 5a of load current with an output voltage adjustable over a 1.2v to 32v range. it offers several features that make it an attractive choice for various power supply applications:. 15 amp, variable voltage regulator circuit. the ic lm 338 alone is specified for handling a maximum of 5 amp of current, however if the ic is needed to handle higher currents, in the region of 15 amps, it can well be modified to produce that much of current with the appropriate modifications as shown below. the circuit utilizes three ic lm338. The 5a variable power supply uses the lm338 voltage regulator. this is a three terminal adjustable regulator that is capable of delivering up to 5a at a voltage range of 1.2 to 30 volts. this regulator has the special characteristic that it allows current peaks of up to 12a, for a short period of time. a thermal overload protection is also. Step 4: bridge rectifier. the rectifier bridge convert an alternating voltage or current into corresponding direct current (dc) quantity. the input to a rectifier is ac whereas its output is unidirectional pulsating dc. the voltage drop across a general purpose diode is around 0.7v and schottky diode is 0.4v.
