Product Description
The TNS series high-precision fully automatic three-phase AC voltage stabilizer is composed of three sets of TND (SVC) series high-precision fully automatic single-phase AC voltage stabilizers. Each phase is regulated separately, ensuring stable and safe voltage for each phase. The grid input is a three-phase four-wire system with a star (Y) connection, and the output can be either a three-phase four-wire system or a three-phase three-wire system. This product features non-distorted waveforms, reliable performance, and can operate continuously for extended periods. It can be equipped with optional protection functions such as overvoltage, undervoltage, overcurrent, phase loss, short circuit, surge, and delay. It is widely applicable to any environment requiring stable voltage, making it an ideal voltage stabilization power supply to ensure the normal operation of your electrical equipment. Customizable input with a delta (△) connection is available.
