Cree’s CRD
-06600FF10N reference design board has certain overvoltage, undervoltage and
overcurrent protection functions. The trip points are the set points that will trigger the protection
functions. If the voltage or current approaches the level indicated in the Table 9 then the unit will
stop operating. Table 9 also indicates how to reset the fault after the fault condition is cleared.
Table 9: Trip
Points of Cree’s CRD
-06600FF10N Reference Design Board
If a trip point occurs so that the board must be reset or powered back ON, you must first turn
the board OFF. The DC link capacitors remain charged for at least 30 minutes after the circuit
is turned OFF, although you may decrease the time that it takes for the board to be fully
discharged by adding a discharge circuit to the DC link. Allow the unit to fully discharge before
turning OFF any of the digital logic/DSP power supplies, and do not touch the unit until it has
been fully discharged. Please check the DC link voltage with a multimeter to ensure that the
board has fully discharged and is therefore safe to handle and power ON or reset.
