Function and Usage
The TNSC series voltage stabilizer (hereinafter referred to as the stabilizer) is suitable for various places that require stable load voltage. When the power supply voltage fluctuates, the stabilizer can automatically stabilize the load voltage within the allowable deviation range of the rated value. This series of stabilizers mainly applies to three-phase three-wire power supply, and the input does not need to be connected to the neutral wire. This series of stabilizers are mainly developed and designed for various machine tools and CNC equipment in industrial applications, and can provide voltage stabilization for air compressors, laser cutters, CNC machining centers, tool grinders, spark machines, etc., ensuring the stable operation of the equipment.

| Note 1: | This product series has a rated frequency of 50Hz. If used in a 60Hz power grid, it can be customized by contacting the manufacturer. | |
| Note 2: | When using three-phase four-wire power supply, i.e., the power supply is A phase, B phase, C phase, and neutral wire (the neutral wire is in a direct-through state). If the output terminal needs to be connected to a single-phase load, ensure that the three-phase voltage loads are balanced. | |
