JSG Series Three-phase Dry-type Transformer (Servo Transformer)

The JSG series three-phase servo transformers are widely used in CNC systems. This series is more energy-efficient, improves the reliability and service life of the transformer, and features heat resistance, moisture resistance, stability, low-temperature resistance, and radiation resistance. The JSG series three-phase dry-type transformers are suitable for various three-phase power supply applications with AC 50~60Hz and input/output voltages not exceeding 500V. Customization options include input/output voltage levels, connection groups, number and position of tapping taps (usually ±5%), distribution of winding capacities, configuration of secondary single-phase windings, integration of rectifier circuits, and requirements for enclosures. All designs can be meticulously manufactured according to user specifications.
