Voltage Control

Our range of Servo Controlled and Solid-State AC voltage stabilisers offer solutions to meet the most exacting requirements, from 1kVA up to 4mVA across single or 3 phase applications.

Our digital voltage stabilisers provide flexible input control along with a host of optional extras to satisfy the most complex applications in the most demanding environments.

EM Voltage Stabilisers

Our electromechanical (EM) Voltage Stabilisers deliver the most cost effective and efficient way to ensure a stable, undistorted mains supply for most applications.

Here are some of the many benefits:

Solid-State Voltage Stabilisers

Our BE solid-state Voltage Stabilisers give ultrafast correction time, coupled with maintenance free operation.

Nuclear Applications - EMS/N (UL Approved) Voltage Stabilisers

Our EMS/N Voltage Stabilisers are designed specifically for nuclear applications to meet the stringent criteria required for the nuclear power generation industry and other safety critical applications, such as telecommunication relay stations and mobile phone transmission sites.

Contaminated Environments - H2s Voltage Stabilisers

Designed for contaminated environments, the H2s range of voltage stabilisers has been developed to work in contaminated environments including hydrogen sulphide gas. The H2s range is available in both single and three phase models.

EM Lite Voltage Stabilisers for Home Use

Our EM-Lite Voltage Stabiliser is the perfect solution for low cost applications, such as houses and small offices.
