Abstract :
This project presents the design and construction of a low cost under and over voltage protective device, which was fabricated using a Nano microcontroller, IC 7805, solid state relay and other discrete components. A microcontroller Nano 328 is at the heart of the device which performs the major control of the device. The device is simple and of low cost. It can withstand loads up to 10 VA and the required set voltage range for the device to allow supply to the connected load at the output varies from 9-12 Volts. It can be used to protect loads such as home appliances etc., from undesirable over and under voltages, as well as surges caused due to sudden failure or resumption of mains power supply. This device can be used directly as a standalone equipment between the mains supply and the load, or it may be inserted between an existing automatic or manual stabilizer and the load. The over is under voltage cut-off with time delay provides over or under-voltage protection using solid state relay.

Keywords : Nano microcontroller, Automatic or manual stabilizer.
