Ok yan, an extra tap for 100v. Actually any AVR with 110V out can be modified to supply 100V. Pwede pa nga any voltage from 90 to 130 and 180 to 260 if there's any application for that.
I wanted to know the difference between a stepdown transformer and an AVR.
Stepdown transformer
- The ratio between input (primary) and output (secondary) is fixed. Any fluctuation in the line voltage affects the output.
- Maintenance-free
- More energy efficient
- High tolerance to short overloads
- Recommended if your line voltage is within +/-10%
AVR
- Electronics circuitry corrects line voltage fluctuations to maintain stable outputs (Major advantage)
- Requires periodic maintenance
- Less efficient than stepdown transformer
- Moderate to low tolerance to short overloads
- Recommended if your line voltage goes beyond +/-10%
