High Voltage Power Supply

High Voltage Power Supply

High voltage power supplies have the ability to have positive, negative or reversible polarity and come in many different configurations, including PCB mounted, internal, open frame, rack or DIN rail. Many different industries require power supplies that generate high voltage, including the telecommunications (for internet, telephone and radio), scientific lab testing, video technology, semi-conductor, industrial, medical and laser industries. Medical equipment, food processing and packaging machinery, HeNe lasers, scientific experiments that require strong electric fields or generate micro waves, negative ion generators and plasma and x-ray tubes all need high voltage power supplies that must be ISO tested and certified. Many have one or more outputs and specifications that include maximum and minimum voltage, current power, output polarity and number of outputs. Many manufacturers are able to supply custom made power supplies built to unique specifications. High voltage power supplies are often used in conjunction with circuit breakers and special connectors that minimize the risk of arcing or human hand contact.

All power supplies come in several different configurations and designs. Those that are PCB mounted are attached directly to a printed circuit board. Internal power supplies are intregral components to the machinery or device, and can be open frame or have an attachable cover, while others are mounted on an exterior rack or DIN rail. External high voltage power supplies are usually smaller and have a square, black protective casing. Because these power supplies generate such high voltage, operating temperatures are very important and must be taken into account at all times to prevent overheating which can lead to permanent damage. All modern high voltage power supplies have digital readouts. Some have an interface that is analog, digital panels or computer screens. They come with software to control, record and monitor the power supply's performance and output at all times. These interfaces allow adjustment and control of the power supplier's output voltage. Today, high voltage power supplies are much lighter and less expensive than traditional ferroresonant transformers.
