Industrial equipment is designed to run safely and consistently on a reliable, correctly configured electrical supply. Equipment that is installed or exported to other countries may face: variations in voltage, deviations in frequency, instability of grid supply, electrical noise.
Such issues are especially prevalent on CNC machinery, automation systems, production lines, test equipment and other industry machinery. Based on the actual power required, an industrial transformer, power stabilizer or variable frequency power supply can supply the desired electrical adaptation.
The Standard design for industrial equipment is to use certain electrical parameters to run the equipment. The input voltage frequency phase and power rating of equipment must be the same as the available power supply.
it’s even more complicated when machinery is imported or moved to another country. For instance a piece of equipment rated for a 380V/50Hz power system if it’s used on 480V/60Hz system without checking power requirements, the equipment may run unevenly overheat protection to trip, or performance may drop.
The industrial power solution should be able to convert the existing electrical supply into the one required by the machine.
One of the most typical problems present when installing industrial equipment in a new location are differences in voltage.
Industrial machines may need 220V or 380V 400V 415V 440V 480V or other according to specific voltage issues of electrical supply.
Industrial transformers are used to step up or step down the voltage applied. They allow the correct voltage to be used by machinery and for the equipment to be sold abroad.
Although not a consideration, voltage is not the only factor, if the electrical frequency is excessively high, high frequency can influence the equipment they’re running.
Most of the industrial equipment is designed for 50Hz or 60Hz operation. When equipment is transferred from 50Hz to 60Hz (or vice versa) a normal transformer won’t overcome the problem of differing frequency since the transformer adjusts the voltage but not normally the supply frequency.
Variable frequency power supply. For equipment that needs to be frequency converter, as a variable frequency power supply can be provided as the equipment’s need, output voltage and frequency.
Voltage may fluctuate on industrial installations due to equipment drawing heavy current, loads changing, on long distribution lines or unstable grid input.
An overvoltage can be applied to motors, control equipment, electronic components and other sensitive equipment.
An industrial voltage stabilizer I-stabilizer can be used to control the voltage within a certain range; it may help deliver a more ‘stabilized’ power supply for equipment.
Factories often have motors, variable speed drives, welding equipment, switching devices and many other elements that may cause electrical noise.
Isolation transformer can be used in electric isolation applications to electrically isolate equipment load from incoming power line and to alleviate some of electrical transients.
Industrial transformers are commonly used when machinery requires a different voltage from the available electrical supply.
Depending on the application, transformers can provide:
For instance, an industrial machine rated for 380V supply might need a transformer during its installation if the voltage available in the plant is not the same.
Isolation transformers provide a certain degree of electrical separation between the source of power and the equipment.
Typical applications are CNC, automation equipment, production lines, industrial control, and machine tools for export.
A transformer is capable of voltage conversion but doesn’t automatically adjust for anomalous voltage levels. When the primary issue is erratic input voltage, industrial voltage stabilization units are better.
The industrial voltage stabilizer constantly makes easier the variating output voltage regulating with the input condition and the need of equipment.
They can be used for:
For factories operating multiple machines or equipment with sensitive electrical components, voltage stabilization can be an important part of maintaining consistent operating conditions.
Some industrial machinery requires not only a specific voltage but also a specific frequency.
A variable frequency power supply can generate controlled output voltage and frequency for equipment that needs adjustable or different power conditions.
Common applications include:
For example, when machinery designed for a 380V/50Hz system needs to operate in a 60Hz environment, simply changing the voltage is not sufficient. A frequency conversion solution may be required depending on the equipment design.
The right solution depends on the actual electrical problem.
