작동 원리

It consists of a contact auto-voltage regulator, servo motor, and automatic control circuit. When the mains voltage fluctuates, the control circuit samples and amplifies the signal, driving the servo motor to move the carbon brush along the regulator coil, automatically adjusting the output voltage to the rated 220V for stable regulation.

선택 및 교체 지침
용량 매칭: Prioritize matching by rated capacity (kVA). 유도 부하 (모터, 압축기) require 2.5-3 times oversized selection.
전압 범위: Ensure input range matches local grid; wide-voltage models (예를 들어, TND6) suit highly fluctuating areas.
보호 기능: 과전압, 저전압, and over-current protection are standard. Premium models add delay start and surge protection.
설치: Floor-standing for high power, wall-mounted for limited space, portable for mobile use.
표준: All comply with JB/T 8749.7, ensuring high interchangeability.

Below are the most practical and common applications of CHINT voltage stabilizers (mainly single-phase TND1 and three-phase TNS1) for residential, 광고, 산업의, weak-current, 의료, and agricultural scenarios, matched to real working conditions for easy selection.
