P/OK
Power OK is a monitor signal that indicates the status of the
AC mains and the DC output voltage of the HAM. P/OK is
asserted (active low) when the output bus voltage is within
normal operating range (>270 Vdc) and 20 – 25 ms after DC-DC
converters are enabled by the E/O signal of the HAM. This
provides sufficient time for the converters to turn on and their
output(s) to stabilize prior to P/OK being asserted, (Figure 9).
For momentary interruptions of AC power, the HAM will
provide at least 16 ms of ride through or hold up time (with
1,000 F output capacitor). On loss of power or brownout,
(when the HAM output voltage drops below 270 Vdc) the
P/OK signal will go to an open circuit state (Figure 7),
signaling an impending loss of input power to the converter
modules. P/OK will provide power fail warning at least 1 ms
prior to converter shut down. When the HAM output voltage
drops below 250 Vdc the converters are disabled via Enable
Output (E/O).
