2. AUTOMATIC
VOLTAGE
STABLIZER
The Voltage stabilizer provides an output
voltage with a specified limit for supplying
to load irrespective of wide fluctuation in
the input voltage, independent of load
power factor and without introducing
harmonic distortion.
The voltage stabilizer adjusts automatically
the voltage variation whether high or low to
the proper voltage level necessary for the
safe operation of equipment
Components are assembled on a printed circuit boards as per
the circuit design. The assembled PCB, Relay, Transformer,
switch indicating lamps and power cables are further
assembled to form a compact unit. The whole assembled unit is
enclosed in metal case with an appealing front panel. Finally
the stabilizer is tested for the performance as per the design.

3. Ceramic cores for resistors are
specialized ceramic material made
out of steatite porcelain. These cores
are in the form of rods and tubes of
various diameters and length. It is
manufactured by using highly pure
raw materials like calcined alumina
with addition of small quantity of
pure clay. These are used in
consumer electronic products such
as radios, televisions and
sophisticated electronic instruments.

4. A compact fluorescent
lamp (CFL), also called compact
fluorescent light, energy-
saving light and compact
fluorescent tube, is a fluorescent
lamp designed to replace an
incandescent light bulb; some
types fit into light fixtures designed
for incandescent bulbs.

5. DTP is used for type setting, layout,
printing, graphics and photographs,
etc.
It has wide applications in designing
and producing newsletter, reports,
data sheets, invitations, certificates,
brochures and catalogues, etc.
With the DTP software package
‘PageMaker’ and MS-Word, it is
possible to undertake a variety of work
in the printing and publishing field.
Bilingual software packages like
‘Venus’ and ‘Prakashak’ have further
enhanced the capacity of DTP for
composing and printing text matter
with graphics and combinations of text
with different Indian languages.

6. This digital safe lockers are Electronic safe
locking systems which operates as per the
signals received through the input key
boards . They are tamper proof and provide
many security options for the user. Digital
Electronic keypad entry lock offers several
advantages also as it is not only more
reliable and strong but also easy to use. It
works on keypad number entry and is based
on the combination of locks. The Digital
lockers automatically go into locking mode
if left idle for more than a pre-programmed
time period
DIGITAL
SAFE
LOCKER
A keypad or human interface device sends
the entered code to the mainboard, which
compares the entered combination with
the combination stored on the EPPROM, if
it is, the mainboard applies current to the
solenoid, causing the bolt that lies in it to
retract allowing the locking bolt to be
retracted.

7. DIGITAL
VIDEO RECORDER
(DVR)
A digital video recorder (DVR) is an electronic
device that records video in a digital format to a
disk drive, USB flash drive, SD memory card,
SSD or other local or networked mass storage
device. The term includes set-top boxes with
direct to disk recording, portable media players
and TV gateways with recording capability, and
digital camcorders.

8. The manufacture of distribution
Transformers
can be sub-divided into following operations:
(a) Assembly of the core unit H.T. & L.T.
coils.
(b) Assembly of leads and making of
connections in the coils.
(c) Placing the assembly in the tank.
(d) Testing.
Distribution
Transformers
A distribution transformer or service transformer is a transformer
that provides the final voltage transformation in the electric
power distribution system, stepping down the voltage used in the
distribution lines to the level used by the customer. The invention
of a practical efficient transformer made AC power distribution
feasible; a system using distribution transformers was
demonstrated as early as 1882.

9. Electric Solar Cooler as the names
suggest is essentially and New concept
of a domestic appliance intended for
Cooling in the Summer season It is
operated electrically as well as Sun light
also. Electric Solar Cooler is an essential
appliances to save the electric energy, it
is basic need where the electric energy is
not available, as in Small Towns and
Rural Areas it bi-purpose device, it may
run by Solar as well as Electric Energy .

10. Process of manufacture :
The process of manufacture consist of
cutting of channels, rods, etc to the
assorted size then the operation in
sequence of bending, turning, forging,
drilling and threading is to be done to
make items at per drawing. Then the
hardware is galvanized in the galvanized
tank.

11. Blood pressure apparatus aneroid type
gauge construction made of metal with
high accuracy and the cuff made of
best quality fabric, bladder and tubing
set made of green rubber of best
material, valve made of brass and with
know to release and fix the air inside
the bladder while use of the apparatus,
bulb made of green rubber, unit comes
in the pocket type carry case, easy to
handle.

12. Electronic digital Muscle
Stimulator is equipment used in
physiotherapy treatment that directs
small pulses of electricity to specific
nerves. The purpose is to reduce the
sensitivity of nerve endings in the
spinal cord, thereby closing the pain
'gates.' In an electronic muscle
stimulator circuit, the equipment
stimulates nerves of that part of body
where electrodes are attached. It is
useful to relieve headache and muscle
pain and revive frozen muscles that
impair movement

13. Electronic toys with or remote,
walkie talkie sets for kids, toy radios,
musical toys, hand-held video games,
video games used with T.V, Arcade
entertainment products, educational
toys etc are popular among Indian
children. This report is about a remote
controlled car toy. There are a number
of Remote controlled Toys in the
market.

14. The electronic weighing system
comprises the basic load cell, suitable
signal conditioners and output
recorders/ indicators giving both the
analog and digital output for further
processing. The signals from the load
cell are amplified and fed to
analog/digital converter, which provide
an output in the digital format for
display/ printing/processing etc. The
strain gauge based load cell is the most
popular weight transducer used in the
electronic weighing system.

electrical energy into direct current
electricity. It is also known as storage
batteries and has wide applications in
Automobiles, UPS/Inverters,
Traction/Electrical Sub-Station,
Telecommunication, Solar
Photovoltaic system etc.

16. LED is semiconductor Technology that emits light at
the junction of oppositely charged materials when
voltage forces electron movement. Led based lighting
systems are devices consisting of many LEDs chips
embedded on the LED fixtures base and fitted with
rectifier circuit that provides regulated current
output at the low voltage that makes them to be
operated on AC Circuit because LEDs requires DC
to operate.
The whole PCB circuit board is fitted inside a plastic
enclosure along with the metallic cap and Smokey
reflector

17. LED based
lighting system
has become a popular
substitute for low voltage
lighting as LEDs do not
suffer from low efficiency,
poor reliability and short
life time exhibited by
bulbs. LED’s are favored
over incandescent bulb or
CFL as LEDs convert far
more of their energy in to
light

18. DC Power Supplies
((9V/12V-500mA)
are modular power supplies used as
power source to electronics
equipments and industrial instrum-
entation. It can also be used as a
power pack for radio/ two-in-one,
calculator. The regulated power
supply provides short circuit
protection/over voltage protection in
addition to maintain load regulation
and line regulation. The power supply
is cost effective and versatile. They
are also termed as fixed voltage
power supplies

19. The electrical appliances
do need periodic servicing,
maintenance and repair actively.
Though there are a number of
authorized repair & servicing centers,
provided by the authorized dealers
network but still there is wide spread
need of the repair & servicing centers
to cater the need of repair and servicing
activity for these appliances specially
in semi-urban and rural areas.
