3.14.1 POWER INDICATOR/SOURCE POWER STATUS FLAGS

Monitors available source voltage to determine if sufficient energy is available to sustain rated

output for normal operation. These signals indicate a fault condition until the bulk voltage is

greater than 390V d-c. Once the bulk voltage reaches 390V d-c (indicating that the PFC boost

converter is operating and assuring that full ride-through time is available at rated load) these

signals revert to “normal” (see Table 3-1). These signals will indicate a fault a minimum of 5 mil-

liseconds prior to loss of output regulation due to source power loss, providing a transparent

source power ride-through time of 21.5 milliseconds; POWER STATUS is not reset until the bulk

d-c again reaches 390V d-c; see Figure 3-6 for timing relationships.
