Overview
It is known that the working voltage range of household electric appliance is within 220V±10%, But in reality, the grid power supply would fall to a voltage as low as a value between 140V to 170V during peak hours and it could increase to as high as above 240V on some occasions. This kind of wide voltage fluctuation may affect the normal function of household electric appliance and other electronic devices, or even cause some damage to them. Adopting advanced digital control system, our JAJA series energy saving household use voltage stabilizer features high precision, wide input voltage range as well as high reliability, low power loss and cost-effective. It is an ideal choice for protecting household electric appliance.

Overview
This series of automatic voltage regulators regulate the output voltage by adopting Intelligent Microcomputer Circuit control power relay (Magnetic Latching Relay). There has features with wide input voltage range, no impulse current at startup, low energy consumption, full intelligent control, and high efficiency and stability. It is suitable for air conditioning, audio equipments, lighting and other household appliances, as well as medical equipment, office equipment, factory laboratories and so on.
Features & Functions
1. It adopts power compensated principle to stable voltage, so the power remains constant within the input voltage range.
2. The Zero-crossing Trigger Technology is adopted to the switching of power relay.
3. Full digital display are used.
4. It has function of energy saving.
5. The insulation grade of transformer is up to 220 grade.
6. The core wires winding by the spool disengaged craft, so that can improve the heat dissipation and nice appearance.
7. The transformer adopts VPI(Vacuum Pressure Impregnation) processing, it can effectively reduce noise, enhance mechanical strength, improve insulation grade.
8. Ventilation fans are used to intelligent control its internal temperature, and effectively improve the reliability of the AVR.
9. It also has these following protection functions, like protection of overcurrent, overvoltage, undervoltage, overtemperature.
