CHAPTER 1: INTRODUCTION
Here is an inexpensive auto cut-off circuit, which is fabricated using transistor and other discrete components. It can be used to protect loads such as refrigerator, T.V., and VCR from undesirable over and under line voltages, as well as surges caused due to sudden failure/resumption of main power supply. This circuit can be used directly as a standalone circuit between the mains supply and the load, or it may be inserted between an existing automatic/manual stabilizer and the load.

HIGH AND LOW VOLTAGE CUT OFF WITH TIME DELAY
Overview
The power line fluctuations and cut-offs causes damages to electrical appliances connected to the line. It is more serious in the case of domestic appliances like fridge and air conditioners. If a fridge is operated on low voltage, excessive current flows through the motor, which heats up, and get damaged.
The under/over voltage protection circuit with time delay presented here is a low cost and reliable circuit for protecting such equipments from damages. ....etc
