Technical Article: Power Conditioning for Large Inrush and High Overload Current Applications

From Utility Systems Technologies, Inc.
 

 

Many power conditioners are incompatible or marginally compatible with a common load type: devices or systems that require a large inrush and/or high overloads. Loads that contain devices such as motors, transformers, magnets, etc. fall in this category. Following is a brief discussion on the application of various power conditioner types in large inrush or high overload applications.

Products & Services
Three phase uninterruptible power supplies (UPS) operate in conjunction with existing electrical systems to provide power conditioning, back-up protection, and distribution for electronic equipment loads that use three-phase power.  Search by Specification | Learn more about Three Phase Uninterruptible Power Supplies (UPS)
Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment. Search by Specification | Learn more about Power Conditioners
Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.  Search by Specification | Learn more about Single Phase Uninterruptible Power Supplies (UPS)
Voltage regulators are power converters that provide voltage control capabilities. They accept a voltage that varies over a given range and generate an output voltage that does not vary. Search by Specification | Learn more about Voltage Regulators
