What is Step Down Voltage?

Step Down Voltage refers to the reduced voltage obtained from a transformer when the number of turns in the secondary coil is less than the number of turns in the primary coil. This is commonly used in electrical applications to lower the voltage to a safer or more usable level.

Example Calculations

Example 1:

Using the formula:

\[ SDV = \frac{50}{200} \times 120 = 30 \, \text{volts} \]

The Step Down Voltage (SDV) is 30 volts.

Example 2:

Using the formula:

\[ SDV = \frac{25}{100} \times 240 = 60 \, \text{volts} \]

The Step Down Voltage (SDV) is 60 volts.
