1. Constant Voltage Transformer (C.V.T) : It is an instrument used to protect our electronic devices from voltage surges and spikes. It is a kind of magnetic transformer with a capacitor connected across the secondary winding of the transformer. 2. Uninterruptible Power Supply (UPS) : It is used to supply power to devices for a fixed amount of time without stopping even when there is no incoming power supply.
Difference between C.V.T and U.P.S :
Parameter |
CVT |
UPS |
Power Failure |
Does not work in the case of power failure. |
Provides backup using power failure. |
Battery |
There is no battery involved. |
The battery is involved for backup purposes. |
Power surge and spike |
Provides safety against power surge and spike. |
IT needs CVT installed inside it for protection. |
Power Capacity |
500 W or 0.5 KVA. |
Few watts to hundred kilowatts. |
Main Use |
Maintain stable voltage. |
Provide backup during a power failure. |
Power Persistent |
It is almost 8 milliseconds. |
Mostly 15-30 minutes. |
Components |
High-voltage resonant winding and a Capacitor. |
Rectifier, UPS Batteries, Inverter, Static Bypass Switch. |
Size |
Slightly smaller than UPS. |
Slightly larger than UPS. |
Pricing |
Cheaper than UPS. |
Costlier than CVT. |
Noise |
CVT usually creates more noise. |
Creates less noise than CVT. |
