NEW FEATURE (Optional) 

​Rupture Detection (quench) feature that is designed to monitor the output voltage and current applied to the load and respond when the circuit has been ruptured (open). This feature is used when it is undesirable to continue applying a voltage/current to the load when the load has opened. The feature will disable the outputs before the set current pulse width is completed. The feature utilizes independent voltage and current circuits that can be used individually or logically OR’d together to disable the output in the event that a ruptured circuit is detected.

​

The rupture detection uses three optional methods to determine when the load has opened:

• Voltage Monitor – Detects a rapid increase in the drive voltage as the result of the control loop trying to maintain current flow into an open circuit. This is most sensitive in low current situations.

• Current Monitor – Detects a rapid decrease in the current flow due to an open circuit. This is most sensitive in high current situations.

• Voltage/Current Mode – Monitoring both voltage and current is the default operating mode as it provides good detection sensitivity across all current levels.
