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.

▌Voltage Stabilizer Functions Features:
▌Protection Function:
☑Overload Protection:
When the load power reaches 120%, the voltage stabilizer automatically activates protection, cutting off the output.
☑Overvoltage Protection:
When the output phase voltage exceeds 250V, the overvoltage indicator lights up, and the output is automatically cut off.
☑Undervoltage Protection:
When the output voltage drops below 184V, the undervoltage indicator lights up, and the output is automatically cut off.
☑Delay Protection:
Upon power-up, a delay of several seconds is automatically initiated before voltage stabilization begins.
☑Short Circuit Protection:
When a short circuit occurs, the voltage stabilizer automatically stops output and requires manual reset to restore output.
☑Over temperature protection:
Over-temperature protection will shut down the regulator if it exceeds a safe operating temperature, preventing damage to its internal circuitry.
▌Product Characteristics:
0.01-second response time for instantaneous voltage stability.
6 high-power coils, three-phase independent control, independent output, ensuring stable voltage for each phase.
Intelligent chip independently and accurately controls each phase voltage, outputting a precise and stable 380V.
Uses high-quality pure purple copper voltage regulating coils, tightly wound, excellent core quality, stable and reliable performance.
Uses 1017 carbon brushes, more precise voltage regulation, no tripping, stable performance, service life up to 8 years.
▌Application:
This series of voltage stabilizers is widely used in industrial, agricultural, medical, broadcasting, telecommunications, scientific research, cultural fields, and other areas where small and medium-sized electromechanical equipment, production lines, construction machinery, microcomputers, embroidery machines, air conditioners, refrigerators, audio equipment, televisions, and other household appliances, lighting, and other equipment requiring voltage stabilization are used.
