Invertor voltage stabilizer SUNTEK QUANTUM 2000VA

SUNTEK QUANTUM 2000 VA is a single-phase online inverter voltage stabilizer with double-conversion technology, designed to supply multiple sensitive electronic devices in power networks with unstable electrical parameters. The unit is engineered for continuous operation and is intended for applications requiring stable and safe power supply for several electronically controlled devices simultaneously.

The stabilizer contains no mechanical regulating components and does not utilize an automatic bypass system that transfers raw utility voltage directly to the load.

Operating Principle

The stabilizer operates using double-conversion technology:

• incoming AC voltage is converted into DC voltage;
• the DC voltage is then converted back into a newly generated AC output with precisely controlled parameters.

As a result:

• output voltage is independent of input voltage fluctuations;
• no step-switching occurs;
• response time to voltage changes is effectively zero.

Regulation and Protection

Voltage regulation is performed entirely electronically, without relays or servo motors. In the event of overload, abnormal operating conditions, or an internal fault, the stabilizer does not transfer utility voltage directly to the load. Instead, it safely disconnects the connected equipment.

Applications

The SUNTEK QUANTUM 2000 VA can simultaneously supply power to multiple devices, provided their total power consumption does not exceed the stabilizer's rated capacity, including:

• gas boilers together with circulation pumps and boiler automation systems;
• refrigeration and HVAC equipment;
• servers, routers and network infrastructure;
• CCTV and security systems;
• household appliances with electronic controls.

Its additional power reserve allows protection of entire engineering systems rather than a single device.

KEY ADVANTAGE

Unlike many competing inverter stabilizers, SUNTEK QUANTUM models do not employ a potentially hazardous automatic bypass system that can transfer unstabilized utility voltage directly to connected equipment.

Therefore, in the event of overload, abnormal operating conditions, or internal malfunction, the SUNTEK QUANTUM does not pass raw input voltage to the load (a phenomenon commonly known as Active Bypass within the 187–240 V range). Instead, the stabilizer safely disconnects the load.

The protection philosophy is different:

• output voltage is always generated by the inverter stage;
• output power quality does not depend directly on utility power conditions;
• during overload or fault conditions, the stabilizer does not transfer raw utility voltage to the load but safely disconnects it, protecting connected equipment.

Consequently, only two operating scenarios are possible:

Scenario 1

Stable 230 V output with ±2% regulation accuracy and a pure sine wave.

Scenario 2

Complete protective shutdown of the load without risk of equipment damage.

A situation where 187 V, 240 V, or any other unstabilized utility voltage reaches the connected equipment is structurally impossible by design.
