TNS Series 3-Phase Voltage Stabilizer | High Precision for CNC & Medical
The TNS Series is a high-precision, contact-type 3-phase automatic voltage regulator designed for environments with sensitive electronic loads. Unlike standard regulators, the TNS utilizes a compensating transformer structure combined with a servo motor mechanism to deliver a clean, stable output (±0.5%) without introducing harmonics. It is the preferred solution for CNC machining centers, medical imaging equipment, laboratories, and high-end automation systems requiring a pure sine wave.
True High Precision: Maintains output voltage at 380V/400V/415V ±0.5%, ensuring optimal performance of sensitive electronics.
Zero Waveform Distortion: The compensating circuit design ensures the output waveform is a pure sine wave, identical to grid power, with no additional harmonics.
High Reliability: Built with a robust carbon brush and servo motor system for smooth, continuous voltage correction.
Comprehensive Protection: Features over/under-voltage cut-off, over-current protection, phase failure detection, and manual/auto bypass functionality.
Intuitive Control: User-friendly digital LED panel displays real-time phase voltages (R/Y/B) and system status.
Compact & Efficient: High-efficiency silicon steel core minimizes energy loss while maintaining a small footprint for easy installatio

Q: What is the main difference between the TNS and SBW series?
A: While both are servo-type regulators, the TNS series is a "compensated" type, meaning it uses a separate buck-boost transformer to correct voltage. This results in a pure sine wave output with zero distortion, making it ideal for sensitive electronics. The SBW is a direct-contact type, generally used for heavier industrial loads where slight waveform changes are less critical.
Q: Can the TNS handle 100% unbalanced loads?
A: Yes, the TNS series is designed to regulate each phase independently, allowing it to handle 100% phase imbalance effectively.
Q: Is this suitable for powering a CT or MRI machine?
A: Absolutely. The TNS series is specifically recommended for medical imaging equipment because it guarantees a pure sine wave and precise voltage, which is critical for the accuracy of these devices.
