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

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

circuit for timer based automatic power cut off gor industrial sealing packing machine

ABSTRACT

Now a day's every system is automated in order to face new challenges. In the present daysAutomated systems have less manual operations, flexibility, reliability and accurate. Due tothis demand every field prefers automated control systems. Especially in the field ofelectronics automated systems are giving good performance. Sometimes the term automationmeans with less intervention of human.The main goal of our project is to control the machine ....etc
