FAQ

What voltage issues can the DVR solve?

The DVR effectively mitigates voltage sags, voltage swells, flicker, and three-phase unbalance. It is particularly suitable for protecting sensitive loads such as semiconductor production lines, precision manufacturing, data centers, and medical equipment.

How fast is the DVR response time?

The DVR can detect voltage sags and inject compensating voltage within 1ms, ensuring “zero downtime” for sensitive equipment during grid disturbances.

What is the conversion efficiency of the DVR?

The DVR uses a single-stage AC/AC conversion topology, achieving a conversion efficiency of up to 98% and a bypass loss below 0.3%, offering significant energy savings.

How does the DVR compare to traditional voltage stabilizers in size and weight?

The DVR is only one-sixth the size and one-eighth the weight of traditional voltage stabilizers. Its electronic layer has an IP65 protection rating and can be wall-mounted or embedded in distribution cabinets for flexible and convenient installation.

Does the DVR support remote monitoring?

Yes. The DVR supports wave-free carrier communication as well as wifi and 4G wireless communication, allowing users to view equipment operation status and adjust parameters at any time, enabling intelligent operations.
