Frequently Asked Questions (FAQ)

What are the core operating features of the VAAS system?

The VAAS system is maintenance-free with extremely low operating costs and no environmental pollution. It features strong overload and dynamic response capabilities, an extremely low failure rate, zero harmonic interference on the grid or load, and an efficiency rate of up to 99%.

How does VAAS handle normal power supply and voltage fluctuations?

VAAS operates in a parallel mode. It remains on standby when the power supply is normal and automatically activates when the power supply voltage fluctuates to protect the load.

What is the response time of VAAS during a voltage sag?

The VAAS system features a rapid 1ms response time, allowing even the most precise and sensitive equipment to safely overcome voltage sags without interruption.

What charging technology is utilized by the VAAS system?

VAAS utilizes supercapacitor constant current and constant voltage isolation charging technology, which ensures fast and safe charging of the energy storage components.

How does VAAS transition back to standby after a sag ends?

By employing phase automatic tracking technology, VAAS ensures a flexible, disturbance-free transition back to standby mode once the voltage sag has ended.
