Invertor voltage stabilizer SUNTEK QUANTUM WI-FI 2000VA

The SUNTEK QUANTUM 2000 Wi-Fi is a single-phase inverter voltage stabilizer featuring double-conversion technology and an integrated Wi-Fi module. It is designed to supply sensitive electrical equipment operating in environments with unstable mains voltage while providing remote monitoring of power network parameters. The unit is engineered for continuous operation and prioritizes maximum protection of connected equipment.

Unlike conventional stabilizers, the SUNTEK QUANTUM does not utilize mechanical voltage regulation components and does not employ an automatic bypass that transfers raw mains voltage directly to the load.

Operating Principle

The stabilizer operates using a double-conversion topology:

• Incoming AC voltage is converted into DC voltage.
• The DC voltage is then converted into a new AC output voltage with precisely controlled parameters.

This technology provides the following advantages:

• Output voltage remains independent of input voltage fluctuations.
• No step-switching transitions occur during operation.
• Zero response time to changes in mains voltage.

Key Safety Advantage

SUNTEK QUANTUM inverter stabilizers are designed without the potentially hazardous active bypass mode found in many competing products.

In the event of overload, operating conditions exceeding permissible limits, or an internal fault, the stabilizer does not transfer incoming mains voltage directly to the connected load (a phenomenon commonly known as active bypass operation within the 187–240 V range).

Instead, the SUNTEK QUANTUM automatically disconnects the load, ensuring maximum protection of connected equipment.

Wi-Fi Connectivity and Smart Home Integration

The stabilizer is equipped with a built-in 2.4 GHz Wi-Fi module for remote monitoring and control.

Supported functions include:

• Remote control of connected equipment via the Smart Life and Digma Smart Life mobile applications.
• Real-time power consumption monitoring.
• Programmable operating schedules (automatic power ON/OFF).
• Retention of Wi-Fi settings during power outages.
• Push notifications in the event of a power failure (sent approximately 30 minutes after loss of mains power, with protection against false triggering).
• Integration with smart home ecosystems, including Yandex Alice (via Digma Smart Life).

• Voice control functionality.
