Product Highlights
Oil-Cooled Design for High-Power Applications
The TNSJA uses insulating oil as the cooling and insulation medium. Heat generated during operation is efficiently transferred away from internal components, making the stabilizer suitable for high-capacity applications and continuous operation.

Automatic Three-Phase Voltage Regulation
The intelligent control system continuously monitors the three-phase input voltage and automatically controls the voltage-regulating mechanism to maintain a stable output.

High Load Capacity
Designed for demanding industrial loads, the TNSJA series is suitable for:

Large motors
Pumps
Compressors
CNC machinery
Production lines
Industrial HVAC systems
Mining equipment
Welding equipment
Large manufacturing equipment
Stable Output Voltage
The stabilizer can maintain the output voltage within the specified accuracy range, helping reduce the impact of voltage fluctuations on electrical equipment.

Typical output accuracy:

±8%

Other accuracy requirements can be customized.

Excellent Heat Dissipation
The oil-cooling system provides efficient heat transfer and helps maintain stable operating temperatures during high-load and continuous operation.

Long Service Life
High-quality transformers, regulating components, control systems, and insulation materials are selected for reliable long-term operation.
