Key specifications and features
Capacity: 20kVA (20,000 Volt-Amperes). This is suitable for handling the power load of most homes, small offices, or large individual appliances like a central air conditioning unit.
Input Voltage Range: Wide ranges are common, such as 130V to 260V or even 80V to 260V, allowing the unit to correct severe power fluctuations.
Output Voltage: A steady, regulated output, typically 220V, with a high degree of accuracy (e.g., ±3%).
Technology: Servo motor-controlled with a toroidal transformer system.
Display: Many models feature a digital LED or LCD display to show the input and output voltage.
Efficiency: High efficiency, often above 97%, means less power is wasted as heat.
Protection Features: Common safety features include over-voltage, under-voltage, short-circuit, and high-temperature protection.
