... PART NUMBER: VMS-365 series POWER OK The POK pin of J3 shall change from the low STATE (<400mV) to the high STATE (>4.5V) 100 500 mS after the main outputs are within the regulation limits. Conversely, the POK should be de-asserted to a low state when any of the main output voltages fall below its under-voltage threshold, or when the main power has been removed for a time sufficiently long such that the power supply operation cannot be guaranteed beyond the power-down warning time ...
