Q1: What does the adaptive input tolerance (±15% above 380V, ±20% below) mean in practice?
This intelligent feature means the stabilizer can handle a wider range of low-voltage conditions. If your grid voltage frequently drops below 380V, it can correct inputs as low as 304V (±20% tolerance). For voltages above 380V, its correction range is a slightly narrower ±15%. This design prioritizes protection against the more common and damaging issue of undervoltage brownouts.
Q2: Can this 80 kVA stabilizer protect an entire small manufacturing plant or a large data hall?
Yes, an 80 kVA unit is precisely designed for such applications. It can be installed as the primary voltage guard at the main distribution point for a small to medium-sized manufacturing plant or to protect a dedicated zone (like a data hall) within a larger facility, ensuring all downstream equipment receives clean, stable power.
Q3: What are "phase failure" and "phase sequence" protection, and why are they important?
- Phase Failure Protection: Detects if one of the three power phases is lost (a "single-phasing" fault). This condition can severely damage three-phase motors. The protection will shut down the stabilizer to prevent damage.
- Phase Sequence Protection: Ensures the three input phases (L1, L2, L3) are connected in the correct order. An incorrect sequence can cause motors to run backwards. The protection prevents operation until the wiring is corrected.
These are critical for the safety of three-phase rotating machinery.
