Actionpower’s VQC series voltage sag mitigation device suppresses voltage sags and enables fast voltage regulation to protect end-user equipment against sags & swells.
Adopting advanced power electronics, the VQC connects in series with the distribution system. It resolves voltage sags, swells and fluctuations to guarantee stable, reliable load operation.
No series-connected semiconductor devices on the main circuit. A built-in triple fault safety bypass maintains power supply during device failure.
Maximum unit capacity up to 2500kVA. Ideal for centralized protection of high-power loads with much smaller footprint compared with alternative solutions.
Low maintenance workload, low cost and zero environmental pollution.
Operates at ambient temperature up to 45°C, no extra air conditioning required.
Output voltage distortion rate ＜3%, no harmonic pollution to the grid or loads.
Modular design for power units and electronic bypass units for simple and convenient installation
VQCP is a high-reliability power protection device using energy storage and seamless voltage-source switching technology. Built on independent power modules, it supports parallel capacity expansion for varied power demands. It continuously monitors grid voltage. When voltage deviates from rated value, thyristors trigger. By controlling the PWM converter output and feeding power to loads via an injection transformer, it shields protected loads from voltage sags.
Efficiency up to 98%, response time ≤2ms.
Residual voltage from 0~130% can be compensated to 100%; rated voltage adjustable within -10% ~ +10%.
Multi-level protection, simple circuit, high reliability, maintenance-free and unattended operation.
Parallel capacity expansion enables mutual redundancy while increasing VQCP system capacity, further improving power supply reliability.
Modules adopt advanced thick-film coating process internally with high protection grade, applicable for high-altitude areas
