FAQ
Q1. Which types of systems are supported by the AVF-133?
It supports 1-phase 2-wire, 3-phase 3-wire, and 3-phase 4-wire systems for flexible use across different panel types.
Q2. Can I adjust the CT ratio for different loads?
Yes, the CT ratio is programmable from 5/5A up to 10000/5A, making it suitable for a wide range of current ratings.
Q3. What protection does the front of the meter have?
The front offers IP65 protection, providing resistance against dust and low-pressure water jets when properly installed.
Q4. Does AVF-133 show only basic V, A, and Hz or more parameters?
In addition to voltage, current, and frequency, it also provides phase sequence indication, RPM indication, and load hour counting.
Q5. Is AVF-133 suitable for industrial panels?
Yes, with Class 0.5 accuracy, IP65 front protection, and a compact 96×96 size, it is well-suited for industrial and OEM panels.
