Yaskawa 6425456 1KVA Transformer Numerical Control Single-phase

Description:

The Yaskawa Electric 6425456 1KVA transformer is used in numerical control (CNC) systems to step down and regulate voltage for control circuits and electronic components. Commonly installed in CNC machines, machining centers, and industrial automation equipment such as Mori Seiki systems. Maintenance teams and system integrators use this part for repair, retrofit, and replacement of control transformers in Yaskawa and CNC control systems.

Applications:

The 6425456 transformer is widely used in industrial automation environments such as CNC machining centers, lathes, and manufacturing systems. It functions as a control transformer, converting incoming line voltage (typically 200–240V) to lower control voltages (around 85–100V), ensuring stable and isolated power supply for control circuits and electronics. These transformers are critical for protecting sensitive components and maintaining reliable operation in machine tool control systems.
