Automatic Voltage Stabiliser

SERVO ELECTRONIC DESIGN - SES Model

SINGLE & THREE PHASE voltage stabilisers

constant Voltage Regulation
REGARDLESS OF LOAD CHANGE

Ashley-Edison AC Automatic Voltage Stabilisers

The Ashley-Edison SES AC Automatic Voltage Stabiliser is suitable for all electrical and electronic equipment, continuously monitors the incoming supply and automatically regulates the output, ensuring voltages reaching the load equipment remains constant at the requisite voltage, from no load to full load.

up to 2,500KVA

Wide Input Voltage Tolerance up to ±40%

Precise Output Voltage Accuracy (up to ±0.5%)

< 1.5ms Response Time

delivering stability,
ensuring reliability.

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.

Technical Features

Input Circuit Breaker

All SES Model Voltage Stabilisers are equipped with Overcurrent Protection fitted as standard.

Bypass Control Switch

Manual Electronic Control Bypass Facility for maintenance of Voltage Stabiliser.

Inbuilt High Overload Capability

Suitable for loads with an inherent initial high current draw on start-up.

Transient Voltage Surge Suppression

Protects electrical and electronic loads against harmful high-energy surges, transients and voltage spikes.

Phase Failure Protection

Loading Protection in the event of Phase Failure.

Soft Start-Up Load Protection

Protection of the load from momentary overvoltage situations on startup.

Over / Low Voltage Protection

Ability to automatically shut down the Voltage Stabiliser in the event of the input supply voltage going outside the input voltage window.

Lightning Surge Arrestors

Protection against extremely high voltage surges and transients caused by lightning strikes on the supply line. (Standard for outdoor models)
