Product Information

First, see this circuit. It is a Zener diode and transistor regulator that we are familiar with well. 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. The built in heat-sink ensures the heavy duty die-cast aluminium body stays cool through simple air convection. 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. The operation of this project, so no need to use a PCB. May use point connect the power cord, tighten the nut onto the heat sink. Then, Connect the wires to the other parts onto the heat sink. Choose parts as you want

At this level, it will be maintained voltage is better than on the electric of a car. Its output voltage can be changed from 11V to 16V. Because the components used in this 13.8V power supply circuit there is not much. And most of them are large. Which must be installed on a heat sink. IC1 is temporarily stopped responding. Because it is overloaded. By earlier, the current of 1A flow through the IC1 and the SCR1 into loaded directly. Not through all transistors. What to watch out, when we connect many IC with parallel form, is the average current flowing through the circuit. Each equally. 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.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? Besides, this power supply circuit is also useful as a wide variety. Such as A large DC motor, car audio system, and others. Which you may apply by changing the voltage and current as needed. This circuit is very flexible. 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. Useful on both 12 and 24 volt systems — on 24 volt systems it reduces the voltage down to 12/13.8 volts, and on 12 volt systems it ensures a constant current.

Our new Voltage Regulator does one job, simply and effectively — takes an input of 7-40 volts dc and outputs a regulated dc current. Solar power regulators are used to prevent the battery bank connected to your solar panels from becoming overcharged. 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. For example, the transformer if you want 30A output current. So you need the least of 30A transformer. It is so big.In normal IC-LM338 Can supply up to 5 amps, but to load current maximum 20 amps, we will bring it to parallel. To measure an S5 sender (with bolt down head) measure from the underside of the flange to the bottom of the stem 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. By parallel with the transistor Q2, from the Q3 onwards. Each transistor can increase the current of 5A.

Next look at the full circuit diagram again. At output pin of IC1 will be connected to the Darlington emitter follower with the transistor-Q1. Then, Q1 drives six transistors Q2-Q7 in parallel. Why connects transistor in parallel So, making the voltage output of this circuit is slightly changed the switch from 14V (under no load) It may be of 13V in fully loaded conditions (regulation). 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 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. This 13.8V power supply circuit uses a regulator IC, LM340T-15. It keeps the level of constant voltage of 15V. Inside this IC has short circuit protection and prevents overheating.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. 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. 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. One voltage regulator will replace all of the dropping resistors normally wired in-line on a 24 volt dashboard.

Imagine, you have a lot of power transistors, 2N3055. Because it is popular in the transistor power amplifier. The voltage regulator provides a constant, regulated current and ensures that the gauge read-out does not alter with voltage fluctuations.

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. Solar panel regulators monitor the flow of power between the solar panels and the connected battery. Some regulators may simply disconnect the flow of power when the battery is in danger of overcharging. Others monitor the flow and, when the battery voltage rises to the regulation point, they regulate the flow to hold the voltage at this point for a period of time. This is called the 'absorption' period, and generally allows the battery to become fully charged. The regulator then controls the charge to keep the battery at close to full charge, also known as the 'float' point.
