This universal power supply circuit diagram has two output ranges; one from 2.7 V to 12 V, and the other from 10 V to 24 V. The output is short circuit protected. Current limiting is adjustable. These two features are mainly incorporated for preventing accidental damages to the power supply as well as circuits that get power from this supply.
By following the step-by-step instructions provided in this article, you can successfully build an auto cutoff battery charger using easily accessible components. This homemade circuit will not only charge your batteries efficiently but also protect them from overcharging, ensuring a longer lifespan.
A DC short circuit protector is an essential component in any electrical system, providing protection against potentially hazardous situations. By using readily available components such as the LM358 IC and BC547 transistor, it is possible to create a homemade dc short circuit protector effectively.
The use of Arduino Nano and 16×2 LCD Display has made it possible for individuals to create an Automatic AC-Voltage Protection Device. This device protects the appliances and electrical equipment from any surge, spike, or overload of electricity, giving them a prolonged lifespan.
The battery over current protector circuit using 555 TIMER IC and BC547 transistors is an essential circuit to protect your battery-operated devices from potential hazards. The circuit’s primary objective is to detect when the battery is subjected to over-current and shut off the current flow instantly.
The 12V-Battery Low Volt Disconnect Circuit using LM358 IC and IRFZ44 MOSFET is an excellent solution to prevent your battery from getting completely discharged. The circuit is straightforward, and the components used are easily available. By using this circuit, you can protect your batteries from permanent damage and prolong its lifespan.
The combination of OP295 IC and SUB75N MOSFET provides an efficient and reliable solution for solar power loss protection. The OP295 can accurately measure the solar panel voltage and detect any drop in voltage caused by partial shading. The SUB75N then switches the output current of the solar panel to bypass the shaded area and restore power output to its full capacity. With this solution, solar panels can operate efficiently, generate uninterrupted power
Lead acid batteries require proper protection circuits to prevent overcharging and over-discharging, which can degrade performance and shorten the lifespan of the battery. The LM10C and BD139 transistor are two important components that can be used to design an effective and simple lead acid battery protector.
Building a 20A current monitor circuit using UCC3926 IC is a simple and cost-effective way to measure the current in a circuit accurately. The UCC3926 IC is an excellent choice for applications that require high accuracy and reliability, such as power supplies, motor control circuits, and battery charging systems. With its low quiescent current and overvoltage protection circuit, the UCC3926 IC is ideal for battery-powered applications.
