Product Detail

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.

Does not conflict with SPD, allowing the original system to remain unchanged.

Generally installed in the output of UPS to effectively clear its interferences.

Maximum amplitude is limited to below 370V, which represents the peak value of 260V.

The interference attenuation efficiency is verified to be greater than 90%.

TOVS successfully fills the huge protection blind spot left by traditional SPD.

Can also be installed on the input end of the UPS for comprehensive protection.

Features multiple overvoltage protection functions to ensure overall safety of electrical equipment.

Fault Alarm Function: When a minor malfunction occurs, the [Alarm] indicator light turns on to alert maintenance personnel. Although some functions may be missing during an alarm, the main functions remain effective and do not affect the safe and reliable operation of the load.

Frequently Asked Questions

What level of overvoltage protection does the TOVS device provide?

The TOVS device provides over 90% attenuation of overvoltage caused by lightning strikes, operation, resonance, and similar events. It limits the maximum amplitude to below 370V (which is the peak value of 260V) with an interference attenuation efficiency greater than 90%.

Does the TOVS device conflict with existing SPD systems?

No, TOVS does not conflict with Surge Protective Devices (SPD). The original system can remain completely unchanged. In fact, TOVS is designed to fill the large protection blind spots that traditional SPDs cannot cover.

Where should the TOVS device be installed in a UPS setup?

TOVS is generally installed at the output end of the UPS to clear its internal interferences. However, it can also be installed at the input end of the UPS to provide protection.

How does the TOVS system handle internal faults or malfunctions?

When a minor malfunction occurs, the device triggers a fault alarm and turns on the [Alarm] indicator light. While some auxiliary functions may be temporarily unavailable during this time, the main protection functions remain fully active, ensuring the safe and reliable operation of the connected load is not affected.

What are the core technical specifications of the TOVS device?

Key specifications include a response time of less than 25ns, a suppression frequency range of 75Hz to 100MHz, a maximum suppression current of 120kA (8/20us), a maximum suppression voltage of 25kV (8/20us), and an interference suppression rate between 50% and 96%.
