Answer Posted / loboreliance2003
The circuit drawn pertains to a regular industrial UPS
(Uninterruptible Power Supply), which shows how the
batteries take control during an outage in electrical
supply or variation beyond the normal limits of the voltage
line, without disruption on the operation providing a
steady regulated output (5 Volts by LM7805) and an
unregulated supply (12 Volts).
The input to the primary winding of the transformer (TR1)
is 240V. The secondary winding can be raised up to 15
Volts if the value is at least 12 Volts running 2 amp. The
fuse (FS1) acts as a mini circuit breaker for protection
against short circuits, or a defective battery cell in
fact. The presence of electricity will cause the LED 1 to
light. The light of LED will set off upon power outage and
the UPS battery will take over
The circuit was designed to offer more flexible pattern
wherein it can be customized by using different regulators
and batteries to produce regulated and unregulated
voltages. Utilizing two 12 Volt batteries in series and a
positive input 7815 regulator, can control a 15V supply.
