ENSURING AN EXTREMELY STABLE AC MAINS SUPPLY VOLTAGE
Suitable for most types of electrical and electronic equipment, the feature rich SCR AC Voltage Stabilizers continuously monitor the incoming supply. Should the incoming voltage rise or drop, the stabilizers will automatically control the output to ensure the voltage reaching the load equipment always remains constant at the requisite voltage.
Ultra Fast Speed of Response
SCR AC Voltage Stabilizers deliver an unsurpassable speed of response ≤ 60 ms making them ideal for highly sensitive loads.
Static / Solid State Design
SCR AC Voltage Stabilizers use solid state devices (SCRs) to select transformer taps to regulate the output. Unlike other similar solutions, by nature of their design do not require the SCRs to carry the full load, just a fraction – thereby delivering far superior reliability to similar systems found on the market. With no moving parts, they are virtually ‘Maintenance Free’ solutions.
Automatic Electronic Bypass
Inbuilt as standard on all models, the automatic bypass maintains power to the load and unit functionality, except regulation, in the event of a problem.
All Digital Controls
All digital microprocessor control and operation ensures SCR AC Voltage Stabilzsers provide the highest level of performance. The standard LCD display provides information on the operational status and loading on the stabilizer, and enables the configuration of a number system parameters for more demanding applications where customization is required.
Independent Phase Control
Independent phase voltage sensing and control to ensure the individual phase voltages remain stable – regardless of load unbalance .
Inbuilt High Overload Capability
Ideal for loads with an inherent initial high current draw on start up.
Output Over / Under Voltage Protection
Ability to automatically transfer to Bypass Mode in the event of the output voltage going outside pre-set output voltage parameters.
Automatic Bypass Protection
Transfer to internal bypass operation in the event of a problem.
Digital LCD Monitoring Panel & RS/485 Interface
Displaying real time operational status, key system readings and alarm events with RS/485 Interface ability for remote monitoring. (RS/485 is an add-on option).
ADD-ON OPTIONAL ACCESSORIES
An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive device.Transformers that have a ratio of 1 to 1 between the primary and secondary windings are often used to protect secondary circuits and individuals from electrical shocks between energized conductors and earth ground.
IP54 / NEMA 3 Style Outdoor Enclosures.
Phase Failure Protection
Protection of the load in the event of phase failure.
Protection against extremely high voltage surges and transients caused by lightning induced strikes on the utility supply line.

SCR VOLTAGE STABILIZER INSIDE
DESIGNED SPECIFICALLY FOR TODAY’S MODERN NEEDS
Voltage Regulators are designed to stabilize the voltage when it fluctuates, up or down.
They are essential whenever reliable power is needed or when normal operation of electrical or electronic equipment is disrupted by voltage variations.
In general when suppliers of today’s modern electrical and electronic equipment design their products they do so knowing that most electrical utilities around the world cannot provide or promise better than a ±5% output voltage accuracy of nominal and as such they design their equipment so it is able to operate efficiently within this range.
Our SCR Stabilizers are specifically designed to meet the requirements of today’s modern loads, being feature rich and virtually maintenance free static mains control solutions.
They ensure the availability of a constant voltage at a level that always meets the design requirements of the load equipment, even for the most challenging of power environments or site loads.
Configured for optimal energy efficiency and design life expectancy, Our SCR Stabilizers are supplied by default with the output voltage accuracy set for ±3% (±5% for Input Swing ±45% ±50% Models), being easily site-adjustable to deliver a more or less precise output voltage accuracy – as considered most appropriate for a particular site’s needs / available options.
