12v Ups Circuit Diagram. For a 12v batt the input is supposed to b e 14 4v the diagram shows a 12v adapter because we don t get 14 4v adapter so readers are advised to handle such situation with. The above diagram is a basic uninterupted power supply ups circuit.
This circuit can be adapted modified for other regulated and unregulated voltages by using different regulators and batteries. Here the simple mini ups circuit diagram. Solder the transformer and test the circuit.
All relays 12 volt 400 ohm spdt.
This basic ups circuit is a very simple and inexpensive. Today power supplies are much compact smaller and efficient with their functioning. The high voltage operation renders the system relatively less complex and transformerless. 13 12v 10a power supply circuit diagram.
