Stabilisers
What is meant by stabiliser?
Stabiliser is an electronic appliance which helps to stabilise the current/voltage supplied to our home/office electrical appliances.
Why Stabilisers?
Usually the AC current supplied to our home/office will be in 220-240 volts, but when there is a under or over voltage, the buck or boost operation of stabiliser will helps to cut down or level up correspondingly to ensure the current amount of tolerable voltage was transmitted to the electrical appliance.
Can we use stabiliser for all electrical appliances of our home?
Yes, you can, but please note since this is also an electrical appliance which consumes power, this will leads to increase in electrical consumption, if you consider the safety of the appliances more compared to the money you invest on electrical bills, all good, you can proceed.
How to bypass this usage of stabiliser?
No way, if you are using tv and refrigerator of old models. We need to use stabiliser to ensure the right amount of voltage is supplied.
But in new model of AC, TV and refrigerator, internally fixed SMPS(Switch mode power supply) to all appliance is replacing the stabiliser, because the SMPS is capable of converting high/low AC current to appropriate DC current and splits it out in right amount to all components of the appliance required.
So does that mean SMPS/Stabiliser remedies all low/high voltage fluctuations?
There is a threshold for both SMPS as well as for stabilisers, which will be around 110-290V (varies from appliances to appliances) , and if the voltage fluctuation is too high or too low to which extremes even SMPS and stabiliser too can’t handle, both suffocates and a good quality of fuse attached to this circuit of SMPS / stabiliser will be out, and thus it saves both stabiliser as well the appliance.
Conclusion?
Good to know about the voltage fluctuations in your residential area and act wisely according to that.
