Toggle navigation. Gravely K Wiring Diagram.In this post we will try to analyze a few interesting IC LM based power supply circuits and related application circuits which can used by all hobbyists and professional for their day to day electronic circuits and experiments.

The following circuit examples simply depict few of the very interesting useful power supply circuits using this IC. The first circuit shows the typical wiring format done around the IC. The circuit provides an adjustable output right from 1. This circuit produces an output that may be equal to the input supply voltage but the current is well regulated and can never exceed the 5 Amp mark.

R1 is precisely selected so as to maintain a safe 5 amp maximum current limit that can be withdrawn from the circuit. The IC LM 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 LM for the intended implementations with output voltage that's adjustable as explained for the first circuit. R8 is used for the voltage adjustment operations.

In the above designs, the power supply utilized a pot for implementing the voltage adjustment procedure, the below given design incorporates discrete transistors which can be digitally triggered separately for obtaining the relevant voltage levels at the outputs. The collector resistance values are chosen in an incremental order so that a correspondingly varying voltages can be selected and becomes available through the external triggers.

Other than power supplies, LM can also be used as a light controller. The circuit shows a very simple design where a phototransistor replaces the resistor which normally acts as the component for adjusting the output voltage. The light which needs to be controlled is powered by the output of the IC and its light is allowed to fall on this phototransistor. As the light increases the value of the photo-transistor decreases which in turn pulls the ADJ pin of the IC more toward the ground, forcing the output voltage to decrease which also decreases the light illumination, maintaining a constant glow on the lamp.

The next circuit shows a super simple wiring with the IC LM whose ADJ pin is connected to the output after a current sensing preset. The value of the preset determines the maximum amount of current that becomes permissible through the IC at the output. The circuit below can be used to charge a 12 volt lead acid battery safely.

The resistor Rs may be selected appropriately for determining the desired level of current for the connected battery. R2 can be adjusted for obtaining other voltages for charging other categories of batteris. Some sensitive electronic circuits require a slow start rather than the usual instant start.

The inclusion of C1 makes it sure that the output from the circuit rises gradually to the set maximum level ensuring the intended safety to the connected circuit. IC LM can also be configured for controlling temperature of a certain parameter like a heater.

If the heat from the source tends to increase above the predetermined threshold, the sensor lowers its resistance correspondingly, forcing the output voltage of LM to fall, subsequently decreasing the voltage to the heater element. The following circuit shows another circuit whose current is restricted to 10 amps, that means the output can be made suitable for high current rated loads, the voltage is adjustable as usual via the pot R2.

The given circuit shows a simple configuration which can be used for controlling the outputs of many LM power supply modules simultaneously though a single pot. In the above section we learned a few of the important application circuits using the IC LM, which were basically collected from the datasheet of the IC, if you have more clues regarding such LM based circuits, please let us know through the comments below.

A wiring diagram is a streamlined conventional photographic representation of an electric circuit. It shows the components of the circuit as streamlined forms, and also the power and signal connections between the gadgets. A wiring diagram usually offers details concerning the loved one placement and also setup of tools and also terminals on the devices, to assist in structure or servicing the device.

A pictorial representation would show more information of the physical look, whereas a wiring diagram uses an extra symbolic notation to stress affiliations over physical look. A wiring diagram is usually made use of to repair problems and also making sure that the links have been made which every little thing exists.

A wiring diagram is a basic graph of the physical connections as well as physical format of an electric system or circuit. It demonstrates how the electric wires are adjoined as well as can additionally reveal where fixtures as well as elements could be linked to the system.

Usage wiring representations to assist in structure or manufacturing the circuit or digital gadget. They are likewise helpful for making repair work. Do It Yourself enthusiasts utilize wiring diagrams but they are also usual in residence building and car fixing.

A residence builder will desire to verify the physical area of electric outlets and light fixtures making use of a wiring diagram to avoid pricey blunders and also developing code offenses. A schematic shows the plan and also function for an electrical circuit, but is not interested in the physical layout of the wires.

Electrical wiring diagrams show exactly how the cables are attached and also where they ought to situated in the actual gadget, along with the physical links between all the parts.

Unlike a pictorial diagram, a wiring diagram utilizes abstract or simplified shapes and lines to reveal parts. Pictorial layouts are typically photos with labels or highly-detailed illustrations of the physical elements. If a line touching an additional line has a black dot, it indicates the lines are linked.

A lot of icons utilized on a wiring diagram look like abstract versions of the genuine objects they represent.This power supply circuit is easy to build and cheap.

And it requires only 5 components. But first I wanted to start by creating a simple circuit that converts from the main power voltage, V or V, to 5V. Doing it wrong can cause serious damage, even death. Use the information provided here at your own risk.

If you want a perfectly safe and extremely useful power supply circuit, you should check out this portable USB charger that I built. It even includes a downloadable step-by-step tutorial on how to build it yourself.

This component will give a stable output voltage of 5V up to 1. I can easily figure out how to use the LM by looking in its datasheet. The above image shows the voltage regulator with a 0. There are a lot of opinions on the web around these capacitors. Some suggest 0. And some suggest using both a 0. The values you should use depends on a lot of factors. For example how long the wires are going to be. Probably, almost any capacitor value will work.

It will probably even work without capacitors. The datasheet also says that it needs between 7V and 25V to work correctly. This is relatively easy. These stores usually stock components that should work in a standard power supply without any special requirements. In Australia, Jaycar is a nice option. The input voltage needs to be around V and the output around 12V. This one is for V. If you live in a country with V the stores in your country will probably have the correct version for you.

Therefore, for this reason the power is converted into the recommended forms with desired qualities by using some electronic power converters or power converters.

Like other power supplies, switch-mode power supply is a complicated circuit that supplies the power from a source to loads. This unregulated DC voltage is fed to the large-filter capacitor or Power Factor Correction PFC circuits for correction of power factor as it is affected. This is because around voltage peaks, a short current is drawn through the rectifier, these current pulses have appreciably high-frequency energy which causes the power factor to decrease.

The AC voltage is again fed to the output transformer. Hence, it is used for low-power applications. The isolation of voltage can be achieved by means of a transformer. The switch operation can be controlled by means of a PWM control while implementing a practical fly back converter. Fly back transformer displays different characteristics as compared to general transformer. As shown in the figure, the voltage across this filter capacitor is taken as the output voltage of the SMPS.
