Battery Charger
Using this circuit will give good charging results to the gel cell battery used in the metal detector or any other similar and smaller type battery. This charger is both current and voltage regulated. The output is not short circuit...
In-Car Charger And Switcher Circuit For SLA Battery
This circuit was designed to control power delivery to a Peltier cooler in a vehicle. The power to the load from the vehicle's battery is managed by a Single Pole Double Throw (SPDT) relay.
The circuit utilizes an SPDT relay to...
eliminate wasted phantom power
Most Apple and Windows PCs can enter "sleep" or "standby" mode when not in use instead of being completely shut down. This mode allows the operating system to restore all previous work sessions within seconds upon waking via keyboard or...
Adjustable 1.5 - 35 V DC Regulated Power Supply Circuit
Adjustable 1.5 - 35 V DC Regulated Power Supply Circuit Diagram. This diagram includes three circuit designs and is categorized under Power Supply. For more information, refer to the detailed post titled "Adjustable 1.5 - 35 V DC Regulated Power...
Dual adjustable power supply circuit
The circuit utilizes a three-terminal adjustable integrated voltage regulator. It includes a gear set and a power supply voltage that is stepped down using a transformer rated at 17.5V x 2 AC. The output voltage after the bridge rectifier is...
Adjustable 20V Supply Circuit
This circuit can deliver 3 A or more with a maximum DC voltage of slightly over 20 V. It is designed around the widely available LM317T adjustable 3-terminal regulator and incorporates a PNP power transistor to enhance the current output....
Automatic Mains Disconnect
Downloading and CD-burning programs often offer the option to automatically shut down the PC upon completion of their tasks. However, this energy-saving feature is ineffective if all peripheral equipment remains connected to the mains and continues to consume power even...
Adjustable Regulated Battery Charger
