A voltage stabilizer is a power device positioned between the utility grid and the end user, designed to deliver a highly stable voltage supply with a variation of no more than ±1% from the nominal values, significantly tighter than standard utility tolerances. Static voltage regulators are particularly suited for applications where rapid voltage correction is critical, such as in computers, laboratory instruments, pumps, measurement devices, compressors, asynchronous motors, and medical equipment. Stabilization is performed based on the True RMS voltage, and the system remains unaffected by load power factor (cos φ), operating efficiently under load conditions ranging from 0% to 100% on each phase.
These regulators can accommodate input and output voltages that differ from nominal standards (e.g., single-phase 220V/240V or three-phase 380V/415V), with such configurations adjustable either at the factory or on-site according to the user manual. In industrial environments, three-phase models are typically preferred, while single-phase units are more suitable for residential use. Furthermore, thanks to integrated electronic protection, the regulator disconnects the output voltage electromagnetically in case of over- or undervoltage beyond the set limits, preventing potential damage to connected systems.
