ABSTRACT:
This circuit protects refrigerators as well as other electrical appliances from over and under voltage. By the name itself we can say that if the input voltage is more or less than the required voltage then the electrical appliance is turned off nothing but it gets disconnected from its respective power supply.
This circuit uses an operational amplifier IC LM324 which is used as a comparator. Generally, the IC LM324 consists of four operational amplifiers, of which only two operational amplifi ....etc

Remote Control of Electrical Appliance using
Wireless Technology GSM

Introduction
Wide growth of wireless communication made me think of
using the mobile phones for controlling the electrical
appliance .This can be done simply by sending an SMS from
the users handset .The system do not require any wired
connections for the automatic control of electrical appliance
it can just be done with the help of a Micro controller
interfaced with the GSM modem .A system being proposed
is economical, robust to use and portable. An individual ....etc

PROTECTION FOR YOUR ELECTRICAL APPLIANCES



Here is a very low-cost circuit to
save your electrically operated
appliances, such as TV, tape
recorder, refrigerator, and other
instruments during sudden tripping and
resumption of mains supply. Appliances
like refrigerators and air-conditioners are
more prone to damage due to such
conditions.

The simple circuit given here switches
off the mains supply to the
load as soon as the power
trips. The supply can be
resumed only by man ....etc

REGULATED POWER SUPPLY
1.1 Types of Power Supply

There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronic circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function.
For example a 5V regulated supply:
