Overview
HNS is a regulator specially developed for industrial CNC general purpose equipment. It consists of three groups of contact autotransformer, compensation transformer, servo motor, automatic control circuit and so on.
When the grid voltage is unstable or the load changes, the system automatically detects the voltage sampling, sends signals to the driving motor by the control circuit, and adjusts the position of the carbon brush of the voltage regulator auto-transformer, so that the output voltage of the voltage regulator can be adjusted to the rated value and achieve a stable effect.
This series of regulators have the characteristics of three-phase independent regulation, waveform distortion, high efficiency, reliable performance and long-term operation.
LES regulator can be widely used in CNC machining center, laser cutting, printing equipment, spring machinery, tool grinder, embroidery textile equipment, SMT equipment and PCB drilling machine and other equipment.
Product Features
- Wide Output Voltage Protection Range
Integrated low- and high-voltage protection ensures stable operation when output voltage falls below 330V or rises above 430V, effectively safeguarding connected equipment. - Three-Phase Independent Voltage Regulation
Each phase (A/B/C) is regulated independently, maintaining balanced output even under asymmetric loads or fluctuating grid conditions. - Intelligent Control System
Automatic voltage detection and closed-loop control enable precise and continuous voltage adjustment without manual intervention. - Fast Dynamic Response
Rapid compensation response allows the system to stabilize output voltage quickly during sudden load changes or grid fluctuations. - High Regulation Accuracy
High-precision control components ensure consistent output voltage, supporting sensitive industrial equipment and long-term stable operation.
