A voltage stabilizer is a device which is used to sense inappropriate voltage levels and correct
them to produce a reasonably stable output where the load is connected. Here we will study
the design of a simple automatic AC voltage stabilizer which can be used for the above
purpose. In this circuit, active and passive devices, such as diodes, transformer, resistor,
capacitor, relay, IC etc. have been used. One step down transformer and one step up
transformer have also been used in this work. In case the line voltage crosses a predetermined
threshold, the comparator detects it and its output immediately goes high, switching ON the
transistor and the relay for the desired actions. The relay contacts are appropriately integrated
to the transformer taps for executing the above actions as per the commands given by the op
amp output. The designed circuit operates successfully and the results obtained are
satisfactory. When installed, the relay trips whenever the input voltage crosses 230 volts,
bringing the output to 218 volts and keeps it until the voltage reaches higher levels. When the
voltage drops back to 225, the relay gets de-energized pulling the voltage to 238 volts and
maintains the difference as the voltage further goes down. The above action keeps the output
to the appliance well between 200 to 250 volts with fluctuations ranging from 180 to 265
volts.

Smart charge continuely blenking what is the issue

[@crazyinfotechtamil]

batry Full charged

[@user-of1pk8cy2i]

Thala va in 2 kva luminous inverter...
When ups on it does not convert to main
But
When I off inverter mains coming
What is the problem

[@user-of1pk8cy2i]

Thala va 2 kva luminous inverter
La
In no main
When i on the inverter ups mode is running but when i give main it does not convert to main
But when i off the inverter switch the main comes
