Dimmer Type Servo Voltage Stabilizer
Dimmer Type Servo Voltage Stabilizer
Effelon+ Dimmer Type Servo Stabilizers use precision auto-transformers for consistent, spark-free voltage control.
Designed for long life and high accuracy, they protect machines from damage caused by under or over-voltage.
Built with 100% copper winding and digital monitoring, these stabilizers are ideal for offices, labs, and industries that demand clean, stable power.
Protect your systems. Power with confidence.
