AVR(II)-RAA AC Automatic Voltage Regulator
AVRⅡ- RAA AC Automatic Voltage Regulator is a new type of update product which is researched and developed by our R&D. Compared with old model, it has low loss, instant overload protection, low noise and long lifetime. It is the best choice for home.
How Does This AC Regulator Work?
1. Voltage stabilization: 220 ±2%.
The New digital circuit board of this AC regulator provides high security.
2. Temperature protection
Work environment or electrical equipment temperature ≥115℃, cut off supply power
Work environment or electrical equipment temperature <100℃, restart to supply power
3. Over voltage protection: AC 246±4V
Low voltage protection: AC 184±4V
The protection measure of this high-accuracy intelligent AC regulator is to cut off the power supply voltage.
4. Selectable delay protection
If the former close down input voltage is 140V and the latter start up is 270V, there will be instant overload current and uneven output voltage which can bring impact on the electrical equipment, or even damage it. In such a case, this high-accuracy intelligent AC regulator can be used to protect the equipment.
