You will see there is a lot of modification to achieve this. The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes (2 ma) to the maximum output of three amperes that the circuit can deliver. A bench power supply is an extremely handy bit of kit to have around for electronics hobbyists, but they can be expensive when purchased from the market. My first power supply was a simple lm317 based one with a potentiometer to vary the output voltage. Main using a 18v 2a transformer. The one important feature that was missing was current limiting. And i prefer output voltage from 0.0v, then i add some diode (s) in series to cancel lm317 minimum output voltage 1.25v. In this instructable, i will show you, how to make a variable lab bench power supply with a limited budget.it is a great diy project for beginners as well as any one interested in electronics. Safety limitations when it comes to safety, you must pay attention to the current limiting control feature if you are using a power supply for your very first time. I often end up with the power clips shorting out on the bench and with no problems. I connected an 8ohm load and 1khz input signal to the amp, and powered it up. With the device powered down, adjust the output voltage control, p1, to get zero volts, the current control pot, p2, for optimum current (maximum resistance), and pt to zero resistance. In this instructable / video i will show you how you can make your own variable lab bench power supply which can deliver 30v 6a 180w (10a max under the power limit).

In this project i will show you how to use famous lm317t with a current booster power transistor, and how to use linear technology lt6106 current sense amplifier for precision current limiter.this circuit may allows you to use up to more than 5a,… Diy analog variable bench power supply w/ precision current limiter: The setting up action for this high end bench power supply with variable voltage/current is dependent totally with the current limit feature. With the device powered down, adjust the output voltage control, p1, to get zero volts, the current control pot, p2, for optimum current (maximum resistance), and pt to zero resistance. 106) about a mini bench supply that seemed like just what i needed.

Bench Power Supply Constant Current Ez Set Hackaday from hackaday.com

And has the added feature that you can limit the maximum output current. You can buy bench power supplies of course, but they are not inexpensive. And has the added feature that you can limit the maximum output current. It should be capable of providing several amperes of current for each voltage. In this instructable / video i will show you how you can make your own variable lab bench power supply which can deliver 30v 6a 180w (10a max under the power limit). R2 is selected to acquire a range of around 1.25a max current limit, the minimum allowable being 5ma when the full 250 ohms is set in the path, meaning the current to the laser may be set as desired, anywhere between 5ma to 1 amp. I found when the on/ off switch is pressed after adjusting required volt and current limits, it create a fairly big spike in the voltage. The module is able to supply up to 3a current and is equipped with safety features that help prevent overload and shorts.

The 30v power the high current for the output and the 40v power all the rest of the circuit.

This is because an atx psu is a switched mode power supply which requires a load for it to function. The setting up action for this high end bench power supply with variable voltage/current is dependent totally with the current limit feature. And has the added feature that you can limit the maximum output current. I recently built a mosfet amplifier and decided to test it with my dual bench power supply. Power supply is based around a lm723 voltage regulator chip and has current limiting. Diy bench power supply current limit. Main using a 18v 2a transformer. This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30vdc. In this project i will show you how to use famous lm317t with a current booster power transistor, and how to use linear technology lt6106 current sense amplifier for precision current limiter.this circuit may allows you to use up to more than 5a,… Bench power supplies with adjustable current limiting. Then my bench supplies start dropping the voltage and my current limit drops down to 2 amps from 4 amps. You can buy bench power supplies of course, but they are not inexpensive. The psu fan will turn on and the outputs will supply power to the mother board, cpu, memory and hard drives.

And has the added feature that you can limit the maximum output current. Also allows you to short circuit protection. It should be capable of providing several amperes of current for each voltage. The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes (2 ma) to the maximum output of three amperes that the circuit can deliver. Presented here is a circuit for 30v 10a variable bench power supply that offers variable voltage and current adjustment.
