AMT-Voltage Stabilizers

A Guide to Choosing Voltage Stabilisers Equipment in commercial settings such as manufacturing facilities and industries need voltage as specified by the manufacturer to perform well. A variation in voltage – low or high supply – can interrupt the functioning of equipment and can even cause damage.

Improper functioning or loss of critical equipment such as industrial refrigerators and computers can turn out to be expensive for your business, for they result in high maintenance costs, process crisis, and even business downturn.

Use of right stabilisers can effectively safeguard your equipment, and ultimately your business, from costly voltage problems.

How does a Voltage Stabiliser Function? This electrical device functions by supplying required voltage to your industrial equipment. It serves as a protective wall between the power supply system and your equipment. A voltage stabiliser monitors for, and recognises, any fluctuations in voltage from the power supply to your equipment.

If there is a fluctuation, the stabiliser employs an inbuilt mechanism (known as tap changer mechanism) to generate the required voltage to be supplied to the equipment connected to it (stabiliser). So how do you choose the right voltage stabiliser? As a buyer, you need to be aware of some factors that are important in choosing the right stabiliser for your equipment.

Do the following before shopping for a stabiliser: Specify Type of Power Supply Does the equipment that requires a stabiliser, run on a single phase power supply or three-phase supply? Specify the power supply system when choosing a stabiliser. This is important because voltage requirements vary for each power supply system. The actual supply voltage in the UK is 230 V for single phase supply, and 415 V for a three phase system. Once you define the power supply system, you get the corresponding voltage supply, based on which suitable stabilisers can be shortlisted.

Determine Total Power of Connected Equipment A voltage stabiliser can be connected to a single equipment, or it can feed multiple units. The power consumed by the equipment or the entire system of equipment, as applicable, must be determined. Equipment label or user manuals give power consumption details. Multiply the power value by the utility voltage (230 V for single phase; 415 V for three-phase), for each equipment. Sum individual power values in case multiple units are to be connected to the stabiliser.

Allow a margin of 20 to 25% to the total power value, to get voltage range for stabiliser. But, in general, go for stabilisers that offer support for a wide fluctuation range. Other Factors to Consider

• Choose a stabiliser that facilitates wall-mounting. This is crucial to ensure safety of workers within the facility. Installing stabilisers in unsafe places, particularly where there is a risk of exposure to water, can result in electric shock. Wall-mountable stabilisers minimise such risks.
• Go for stabilisers with time delay feature. This feature helps prevent possible damage to equipment that could result from a spike following a power failure. By delaying power to the equipment by a few minutes, the stabiliser restores balance and prevents damage.
• Check if the stabiliser has overload protection capability. If stabilisers are loaded beyond their specified voltage capacity, they can break down, or worse, cause fire accidents. This protection feature prevents such occurrence by shutting down the stabiliser output completely in case of an overload.
• Opt for stabilisers with a clear specified warranty period.
