5V and 3.3V DC Voltage Regulator BoardThis is the voltage regulator circuit board that delivers steady 3.3V and also 5.0V DC outputs from unregulated DC input (6.5-10V). It is small in size and also is able to be simply assembled within the general project box along with a project circuit board. It could also be applied ...
Universal Battery Charger SchematicThis is the schematic diagram of universal battery charger which using LM317 regulator and SCR C103B. It can be used for universal battery, adjust the R6 to decide the voltage output first before using the circuit to charge the battery. How the circuit works: When the circuit is turned on, ...
Basic Uninterruptible Power Supply DiagramThe following circuit is the basic form of the commercial Uninterruptible Power Supply (UPS), the circuit gives a constant regulated 5 Volt output and an unregulated 12 Volt supply. Within the event of electrical supply line failure the battery pack takes over, with no spikes on the regulated supply. This ...
Discharge Indicator for 12V Lead Acid BatteryThis is the circuit of discharge indicator for 12V lead acid battery. In complete discharge of lead batteries, is feared to be destroyed. This circuit makes the job of detecting this decay, preventing the batteries from damage. When discharging process, the 12V Lead-acid battery voltage must not be reduced below ...
Solar Panel Regulator SchematicThis is the solar panel regulator schematic diagram. The plainest flavor would be the very simple on-off type shunt regulator. It has the benefit of simplicity, really little electrical power dissipation, low cost, higher reliability, but in exchange for these advantages one has to accept that the voltage on the ...
