3.Characteristics
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 30 seconds, stabilizing output voltage automatically.

1, when the load current exceeds the rated current value of the regulator, the regulator will automatically switch to bypass, and displayed on the LCD screen overload, to remind the user to correct. And it can continue to protect equipment from damage running at high speeds. 2.When the load current exceeds rated current value of 10%, the regulator will automatically switch to bypass with to reminding the user to correct.And user will have the time to turn off the machine before the input breaker trips off to protect the regulator itself from damage. |
When the load exceeds the rated current, it will trip off automatically . Due to suddenly power off, it may bring heavy damage to the load,which is running at high speed. | |
