Step-less Voltage Regulation

Automatic and Continuous Incoming Voltage Monitoring – Ashley-Edison Servo Electronic Design (SES) Voltage Stabilisers deliver smooth and stabilised output voltage to the load, protecting operational uptime and efficiency. Precise output accuracy at +/-0.5%, optimising load equipment’s life span.

Independent Phase Control

Independent Phase Balancing and Voltage Sensing Control ensures the individual phase voltages remain stable, regardless of load unbalance. Should the incoming voltage on a different phase rise or drop, the Automatic Voltage Stabiliser will automatically regulate the output voltage before reaching the load end.

Unparalleled Inbuilt Protection and Control Features

Quality Voltage Protection – Ashley Edison’s market leading Electro-Mechanical Servo Electronic Design based SES Automatic Voltage Stabiliser have repeatedly proven their durability and dependability in some of the world’s harshest and most demanding power environments. Providing options of a wide range of input voltage windows and precise tight output voltage regulation, all SES AC Voltage Stabilisers include as standard many advanced protection and control features – such as Independent Phase Sensing, TVSS, Input Circuit Breaker, Bypass Control Switch and Soft

Switch-on.
