STAVOL AVR Heavy-Duty Automatic Voltage Regulators (AVR)
with By-Pass and without by-pass
A lineup of STAVOL servo motor-controlled Automatic Voltage Regulators, featuring a convenient built-in by-pass switch and a mobile cabinet design with wheels for industrial or commercial applications. These high-capacity units, are designed to deliver stable 220V output and pure copper winding for robust protection of sensitive equipment against power fluctuations, over-voltage, and under-voltage.
Feature Specification Range
Capacity : 10 kVA up to 200 kVA
Technology : Servo Motor Control (High-precision, smooth voltage
correction)
Input Voltage : 145V - 260V AC (Wide range to handle severe fluctuations)
Output Voltage : 220V AC (Standard output)
Voltage Accuracy : ± 3% of 220V (High precision for sensitive equipment)
Frequency : 50 Hz / 60 Hz
By-Pass Function : Built-in Manual By-Pass Switch
(Allows power to flow directly, bypassing the AVR
for maintenance)
Winding : 100% Pure Copper (Ensures high efficiency, durability, and a
true rated power output)
Response Time :≤ 1.5 seconds (For a 10% input voltage change)
Time Delay : Short Delay: 5 ± 2 seconds
(Protecting against rapid power cycling)
Long Delay: 3 - 5 minutes
(Protecting equipment like air conditioners/refrigerators)
Protection :Over-Voltage, Under-Voltage, Overload, Short Circuit
Efficiency :≥ 90% (Typically high for servo-motor AVRs)
Display : Digital Display or Analog Voltmeter/Ammeter
(For real-time monitoring of input/output)
