high low volt cut off with delay alarm circuit ppt for pdf

Abstract

This straight forward circuit will protect electrical appliances from over voltage as well as under voltage. The circuit also produces an alarm when the power supply comes back. An ideal circuit for home to protect your valuable equipments from voltage fluctuations. The same circuit with some modifications can be used to make a automatic voltage stabilizer.

When the mains voltage is in the normal level, the voltage at the negative terminal of zener diode D4 will be less tha ....etc

TIMER BASED AUTOMATIC POWER CUTOFF FOR INDUSTRIAL SEALING/PACKAGING MACHINES

ABSTRACT:

The main goal of our project TIMER BASED AUTOMATIC POWER CUTOFF FOR INDUSTRIAL SEALING/PACKAGING MACHINES is to control the machine. This allows us to realize the task efficiently and effectively without the intervention of human by making it automated and even we can avoid unnecessary wastage of power by switching it off at right time.Now a day's every system is automat ....etc

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.
The over/unde ....etc
