Lm338 power supply

If you want to a LM3variable dc voltage power supply circuit during 1. V to 30Vdc and can provide a current maximum to 5A. I am building two of these, with one slotting into my main power station, the PowerStation2. Adjustable Power Supply 1. Constant Current Regulators.

Typical Application Circuit. They are exceptionally easy to use . This kind of dc power supplies uses a PCB so you can use two case types for IC TO-2or TO-3. The regulation of this volt power supply is made with TR( multiturn ). ICmust be placed on proper heatsink. Volt Output adj by VR1-1K.

V 20A High Power Supply with LM338.

IC LM3to hold heat-sink. An LM3regulated linear power supply in operation. It was designed and built from scratch!

It is built around a voltage regulator like the LM3and capable of providing voltages between 12V and V (1 V for example). This circuit can provide a maximum current of A. LM3Circuit 5v…32v – 3A s you know, every electronic circuit needs power. That is why power supplies and voltage stabilizers are one of the most popular topics, enjoying uninterrupted interest. In practical reality, dissipating 75W means you must divide the power between more than one device. That means you get a juntion temp rise of over 100C going from . For most of our Sensors and Motors we use voltage levels like 3. But motors like servo motors or PMDC motors which run on 12V or more, require a high current.

So we are building here the Regulated Power Supply of 3A current with the Variable voltage between to 24v. I try, I never get more than 1. Here, we present a classic adjustable power supply circuit which is based on the LM338. LM3is an adjustable 3-terminal positive voltage regulator and it is capable of supplying in excess of 5A over a 1.

LM3Power Supply - Electronic Schematic. The output voltage can be set at a desired value . The 10V winding is rated at 10A, I thought it would be perfect for a high current power supply project. Rather than designing digitally controlled voltage adjustment circuitry (e.g. via DAC), I decided to . V-at-15A- The circuit was designed based on two types of voltage regulator which utilizes three LM3to produce a maximum 25V at 15A and one LM3to produce a maximum of 25V at 3A. LM3– an adjustable 3-terminal positive voltage regulator capable of . I need to design a LM3regulated power supply for myself. I will be using it to power two small amplifiers that I have.

After many years of employing this ugly and clumsy bench power supply, I decided it was time to build something better, smaller, and well - prettier. The value of the preset determines the maximum amount of current that becomes permissible through the IC at the . Power supply schematic and parts list is provided here.
