v LCD Large-screen

Using large-screen LCD display, can shows dynamic display voltage, current, and all kinds of working condition.


v Product Characteristics

The speed of response time(regulating speed) is very fast, non-contact, anti-interference, no mechanical failure and wear of carbon brush, maintenance-free. Three-phase voltage regulating independently to ensure the balance of output voltage . Effectively protect the security of the precision equipment.


v Precision (output accuracy) Can Be Adjusted

All precision of the stabilizer is preset plus or minus 2 Volt. According to different load demand can be adjusted plus or minus 2 Volt, plus or minus 2 Volt.


v Manual Voltage Regulation

According to production requirement, within the scope of the 10% rated voltage value, the stabilizer can set voltage arbitrarily for different electrical equipment.


v Automatic Bypass Function

Equipped with automatic bypass function, when the stabilizer fails,it can turn into the mains automatically, no affection for the production.


v Output High and Low Voltage Protection Function

When monitoring circuit detect the output voltage beyond the upper or lower limit, voltage stabilizer can turn into the mains automatically, no affection for the production.


v Lack of Phase/Phase Fault Protection Function

When monitoring circuit detected phase failure, voltage regulator /stabilizer will cut off the output automatically and voice-alarm.




v Delay Stabilizing Output Voltage Function

Voltage Stabilizer boot or recover from a state of protection, would not be regulated immediately. But stay on only after users determine that the mains voltage are normal to ensure that the load equipment would not be damaged.


v Automatic Output Function

System preset is automatic output. When stabilizer connect to the mains, system detect that the power grid is normal, then it would delay < 3 ms, stabilizing output voltage automatically.


v Modular Design, Easy to Replace and Repair

Adopting modular design, regulating circuit and monitoring circuits independent to each other, all components are standard-normalization. Assembly, debugging, maintenance are more simple and quick.


v Strong Load/Carrying Capacity

When the short-time overload or short-circuit, the transformer would not be damaged to avoid coil burning fire. When overload 100%, stabilizer can withstand 15 min, 10 seconds for overload 500%.
