Product description

Highlights at a glance

  • High-Precision Single-Phase Voltage Regulation (3 to 50KVA Capacity Range) Engineered for residential, commercial, and light industrial applications, the TND Series Single-Phase Automatic AC Voltage Stabilizer delivers exceptionally stable power output across a broad capacity range from 3KVA up to 50KVA. Designed for single-phase 2-wire electrical grids, it automatically compensates for power drops, line sags, and unstable grid fluctuations, keeping your incoming 220V power precisely within 220V±15% to ensure optimal performance for delicate single phase equipment.
  • apid Voltage Adjustment (> 15V/S}$) & Ultra-High Efficiency (> 98%) Featuring an advanced auto-transformer servo-motor control system, the TND series responds swiftly to grid instability with an adjustment speed exceeding. Despite its fast corrective action, the unit operates with an outstanding efficiency of $> 98%, minimizing power loss and operational heat generation while guaranteeing zero additional waveform distortion to preserve clean sine-wave electricity.
  • Intelligent Safety Protection & Configurable Delay System To shield connected equipment harmful startup electrical shocks grid spikes, the TND stabilizer is built with smart short delay function during power-on. It integrates precise overvoltage protection (225 5V) and supports customizable safety configurations-including undervoltage, extended delay, and overload protection-tailored specifically to regional grid conditions or buyer requirements.
  • Multi-Industry Versatility & Precision Equipment Safeguard The TND Series is an ideal power protection solution across diverse sectors, safeguarding sensitive electronics and high-value machinery, including Medical & Healthcare Medical radiology imaging, diagnostic systems, and laboratory instruments. Industrial & Machining Small CNC machine tools, automated test benches, and voltage testing equipment. Commercial & Office Computers, IT server racks, lighting systems, and commercial printing setups.

    Frequently asked questions

    We commit to 100% pure copper coil construction for all our CNC series transformers. We do not use aluminum or copper-clad aluminum alternatives. Pure copper offers significantly lower internal resistance, superior heat dissipation, and higher energy efficiency, ensuring a reliable lifespan of over 20 years under continuous heavy-duty industrial loads.

    Yes, absolutely. While a standard transformer cannot change grid frequency, our custom-engineered windings and premium silicon steel cores are designed to operate perfectly at both 50Hz and 60Hz. We optimize the magnetic circuit based on your target country's frequency to prevent overheating and voltage drops.

    Yes. This is our core strength. Through our Country-Specific Customization Service, we can design any voltage configuration you need (e.g., 380V to 220V, 415V to 380V, 440V to 200V). Just provide your local grid voltage and the input requirements of your CNC equipment, and we will customize the internal winding ratios before production.

    This is a dry-type isolation and voltage-changing transformer. It features excellent passive voltage regulation and anti-interference capabilities by isolating grid harmonics and suppressing spikes. However, if your local grid suffers from extreme, volatile fluctuations (exceeding $\pm15\%$), we highly recommend integrating our active voltage stabilizer (TND/TNS series) to ensure absolute protection for your servo systems.

    All our power equipment is manufactured under strict quality control and fully complies with international safety standards. Our products are backed by authentic CE and TUV Rheinland certifications. Each unit undergoes rigorous insulation withstand-voltage, fire-resistance, and EMC testing before leaving our facility to ensure hassle-free customs clearance and local safety compliance.

    Our transformers utilize advanced Air Self-Cooling (AN) or intelligent forced air cooling, utilizing high-grade H-class insulation materials that withstand temperatures up to $180^\circ\text{C}$. Combined with our optimized ventilation enclosure (IP20), it ensures safe, continuous 24/7 operation even in high-temperature metal processing workshops or dust-prone environments.

    Yes. Every unit undergoes advanced Vacuum Pressure Impregnation (VPI) with eco-friendly insulating varnish. This process seals the coils entirely, making them highly resilient against moisture, conductive factory dust, and oil mist typical in CNC workshops. VPI also eliminates micro-vibrations, lowering operational noise below 45dB.

    We provide a comprehensive warranty alongside 24/7 remote technical assistance backed by our 20 years of engineering experience. If your local engineers encounter layout, installation, or wiring queries, our technical team will provide step-by-step guidance via video calls and detailed English manuals to get your production line running without delay.
