7.2V Battery Replacement Power Supply For Camcorders
This circuit allows an external 12V SLA battery to power a camcorder that typically operates with a built-in 7.2V battery. Replacement batteries for older camcorder models can be challenging or costly to find. Essentially, the circuit utilizes a standard LM317...
Battery charger or Power Supply 14 volt 4 ampere
The schematic diagram originates from a circuit designed as a battery charger/power supply with an output of 14V and a maximum current of 4A, utilizing the VN64GA MOSFET. This high-performance battery charger is specifically engineered for gelled electrolyte lead-acid batteries,...
10 Amp 13.8 Volt Power Supply
Sometimes amateurs like to home-brew their power supplies instead of purchasing one off the shelf at any of the major ham radio retail dealers. The advantage to rolling your own power supply is that it teaches us how they work...
Adaptive configuration LM317 adjustable power supply
The adaptive adjustable power supply is illustrated in the accompanying figure. The power supply utilizes an LM317 regulator device, and an adaptive switching circuit that automatically adjusts the input voltage based on the output voltage level. This mechanism reduces the...
3-30V-universal-power-supply-module
The LM317 adjustable regulator (U1) offers short-circuit protection and automatic current limiting at 1.5 A. The input voltage to the regulator is provided by a 4-A 100 PIV full-wave bridge rectifier (DB1). Capacitor C1 serves as the initial filtering component....
Industrial fuel oil furnace controller circuit diagram 2
