About this deal

The voltage regulator provides a constant, regulated current and ensures that the gauge read-out does not alter with voltage fluctuations. Our new Voltage Regulator does one job, simply and effectively — takes an input of 7-40 volts dc and outputs a regulated dc current. The output of the LM317 voltage regulator (pin 2) is connected to the 4 power transistors bases. These transistors are connected in parallel. The output voltage of the 20 Amp Variable Power Supply is obtained from the junction of the 4 resistors (R2, R3, R4, R5), connected to the emitters of the 4 transistors.

In the short-circuit conditions. Or Overload, Or Using too many currents. The Q2 is pulled by the current of 5A. Until the voltage of 0.75V drop across R5 – 0.15 ohms. (emitter pin of Q2). Then, this voltage to gate lead of SCR1. Next, it is enough to trigger SCR1 works immediately. But it may do not for sale. We may use five of 4,700uF 25V capacitors to connect together in parallel. So, we have a total capacity of 4,700 μF x 5 is 23,500μF.It is enough to use.As an example; a standard Wema Wema 52mm analogue gauges will draw a maximum current of 130mA, so each 3A voltage regulator can supply power for up to 20 standard gauges. Each 5A voltage regulator can supply power for up to 38 standard gauges.

If your sender has a high or low level alarm we will need to know if the switch is normally off (when the tank is empty), turning on when the tank is full or normally on, turning off when the tank is full. We will also need to know how far from the top or bottom of the sender you would like the alarm switch to be. Tank Contents?Note: Q1-Q7 is 2N3055 NPN power transistor. Also, you may use TIP35 High-Power Transistors in TO-247. But it is more expensive than a 2N3055. Better protection Figure 1 circuit, in normal conditions, the voltage between pin Adj and pin output is equal to a 1.25V stable that flow pass R1, R2 will have constant as well. In 30A output, if you cannot buy a 68,000uF 25V electrolytic capacitor. You may use 10,000uF 25V x 6 connect together in parallel. It saves money and easy. All the electronics are sealed providing IP68 (submersible up to 1.5m deep for at least 30 mins) protection from the elements.

And the transmitter is normally used in the car with 12V battery is designed to be compatible with existing 13-14V voltage. How it builds This power supply is not broken. IC1 can prevent overload very well. Even being a long-short circuit throughout the day. It is still in good condition. In normal IC-LM338 Can supply up to 5 amps, but to load current maximum 20 amps, we will bring it to parallel. To increase the current up. When to connect these 7 transistors Q1-Q7 to complete. It makes can boost up to 30A. If your S5 or S3 sender has 3 or 4 wires then it is either a 0-5v, 0-10v sender or it has a high/low level alarm.The output voltage of the high current 13.8V power circuit is equal to the voltage output of IC1 (15V) minus the voltage drop across the base (B)- emitter (E) of transistor driver (Q1) and the transistor through (Q2) and the voltage drop across R5 emitter of Q2.

What to watch out, when we connect many IC with parallel form, is the average current flowing through the circuit. Each equally. It may have more energy a loss in transistors and ICs. Making must use a larger heat sink. It is too consumes more energy than necessary. One voltage regulator works for multiple gauges, able to provide 12 volts to the whole dashboard and replacing the need for individual dropping resistors on a 24 volt system.

Types of solar power regulators

As a result, this circuit can keep the level output voltage as well. And, If there are overload or short circuit. It will do not damage too.
