TOVS for Control Power Lightning&Interference
Functional features
Over 90% attenuation of overvoltage caused by lightning strikes, operation, resonance, etc;
Simultaneously solving various problems such as normal interference and transient interference;
Not conflict with SPD, and the original system can remain unchanged;
TOVS is generally installed in the output of UPS to clear its interferences;
The maximum amplitude is limited to below 370V, which is the peak value of 260V;
The interference attenuation efficiency is greater than 90%;
TOVS can fill the huge protection blind spot of SPD;
TOVS can also be installed on the input end of UPS for protection.
TOVS has multiple overvoltage protection functions to ensure the safety of electrical equipment;
When there is a minor malfunction in the TOVS device, the device has a fault alarm function, and the [Alarm] indicator light is on for maintenance personnel to check. The TOVS device has an alarm and some functions are missing. The main functions are still effective and do not affect the safe and reliable operation of the load.
