Using relay general the majority then to use power supply that have DC Voltage with the value volt that specify on relay. For relay work but , if , we have no power supply that want to feed give relay. This circuit helps to give relay can work.
From the circuit uses two power supply from [...]
This be basic AC inverter Circuit. Convenient for the initiator who have to is extremely fond of something experience. Because of use IC 555 highly popular, perform produce the frequency ,then enlarge with transistor NPN and PNP number TIP41 and TIP42 drive the coil transformer. Get by can pay Voltage output about 120V to 230V [...]
This is a circuit 3V to 15V Step-Up DC Converter by LT1073.
It is very nice IC Dc converter or Switching power supply.
15V OUTPUT
27mA AT
VBATTERY = 2V
