V110B24C200BL_16 Datasheet, PDF (10/14 Pages) Vicor Corporation – DC-DC Converter Module

Primary Control - PC PIN
Module Enable/Disable
The module may be disabled by pulling PC to 0V (2.3V max)
with respect to the –Input. This may be done with an open
collector transistor, relay, or optocoupler. Converters may be
disabled with a single transistor or relay either directly or via
“OR’ing” diodes for 2 or more converters. See Figure 2.
Primary Auxiliary Supply
During normal operation only, the PC Pin can source 5.7V @
1.5mA. In the example shown in Figure 4, PC powers a module
enabled LED.
110V Input
Module Alarm
The module contains “watchdog” circuitry which monitors
input voltage, operating temperature and internal operating
parameters. In the event that any of these parameters are
outside of their allowable operating range, the module will shut
down and PC will go low. PC will periodically go high and the
module will check to see if the fault (as an example,
Input Undervoltage) has cleared. If the fault has not been
cleared, PC will go low again and the cycle will restart. The SC
pin will go low in the event of a fault and return to its normal
state after the fault has been cleared. See Figures 3 and 5.
