Product Detail

Functional features

High energy nonlinear resistor chip matching technology

The nonlinear resistor adopts unique heat dissipation technology and fully sealed process, with excellent heat dissipation and moisture prevention effects, stable working performance, long service life, and safety and reliability.

Overvoltage peak cutting technology

When a transient overvoltage occurs in the system, when the peak value of the overvoltage exceeds 1.2 times the rated voltage peak value, the overvoltage peak interceptor immediately acts to cut off the high voltage wave head, ensuring the safe operation of various load equipment under the busbar.

Secondary pressure limiting technology

After the operation of the first level voltage limiting unit, if the bus voltage still exceeds the set allowable value, the LOPS equipment will put in an overvoltage chopper to quickly limit the bus voltage to 1.2 times or less.

Rapid response technology

The action delay is small, the first level has no delay response, and the second level responds within 2 milliseconds. Good steep wave response characteristics, short conduction time of nonlinear resistors, active protection, and good protection performance.

Overvoltage recording technology

The LOPS low-voltage bus overvoltage suppression equipment can automatically record parameters such as the number of actions, action time, and bus voltage during action, providing a basis for system technical analysis.

Frequently Asked Questions

How does LOPS equipment compare to traditional Arrestors and TBPs in terms of action voltage?

LOPS equipment has a significantly lower action voltage threshold of 1.25 times, compared to the 2 to 3 times threshold of traditional Arrestors and TBPs. This allows for quicker and safer intervention during overvoltage events.

What is the safety risk profile of LOPS compared to other solutions?

Traditional Arrestors and TBPs carry the risk of running in an unknown status and potentially exploding. LOPS equipment offers a completely controllable operation status, eliminating the risk of explosion.

How does the Secondary Pressure Limiting Technology work?

If the bus voltage still exceeds the set allowable value after the first-level voltage limiting unit operates, the LOPS equipment deploys an overvoltage chopper to quickly limit the bus voltage to 1.2 times or less.

What types of overvoltage can the LOPS system effectively handle?

While traditional Arrestors and TBPs only target specific types of overvoltage (such as lightning or resonance), LOPS equipment is designed to suppress all types of overvoltage in the system.

What is the response speed of the LOPS overvoltage suppression system?

The system features rapid response technology with a response time of ≤50ns. The first level has no delay response, and the second level responds within 2 milliseconds to ensure active protection.
