A crowbar circuit is usually placed across the power supply’s output terminals, to protect the load against any overvoltage. It does this by shorting the terminals (placing a crowbar across) which deactivates the protection device. It may blow up the fuse, trip the circuit breaker or shut ...
Compliance VoltageThe range of output voltage (in a constant current power supply) over which the load regulation is within certain limits is called thecompliance voltage. Crowbar protectionA sometimes used fail-safe mechanism which shorts the outputs of the power supply under failure conditions.Crowba...
The protection of the klystron against self-arcs is extremely important for the power supply. Although the unique design of the power supplies limits the fault current under klystron fault a light triggered thyristor crowbar is also incorporated. The unique characteristics of the light trigged ...
Over-Voltage Protect is provided on some supplies. It is also called a "Crowbar" because it shorts the output of the power supply in the event of a fault that increases the output voltage too much. For example, on a +5V supply, the overvoltage is set to about +6.2V. This is impleme...
