Protection Against Overvoltage Events, Miswiring, and Common
Overvoltage Fault Protection One of the more common faults a system can experience is an Overvoltage Fault. Often caused from either a transient event, unstable power-up or power-down
Remote power supply overvoltage
Probably the most common cause of an overvoltage condition is an operator adjusting the power supply output voltage too high. The remedy is to switch it off, turn the output adjustment potentiometer counter clockwise and re-apply the input power. If the voltage level of an installation goes out of its acceptable limits, the information provided by overvoltage protection can be used to initiate appropriate action to restore good operating conditions in. Most AC-DC power supplies and isolated DC-DC converters will have an Over Voltage Protection (OVP) circuit, which will protect the load in the event of an internal failure. By using this feature, we can protect the device under test (DUT) from...
