24V Maxi Family Rev 6.6 vicorpower.com Page 11 of 15 01/2016 800 927.9474 24V Input Module Enable/Disable The module may be disabled by pulling PC below 2.3V with respect to the –Input. This may be done with an open collector transistor, relay, or optocoupler. Multiple converters may be disabled with a single transistor or relay either directly or via “OR’ing” diodes. See Figure 2. Primary Auxiliary Supply At 5.7V, PC can source up to 1.5mA. In the example shown in Figure 4, PC powers a module enabled LED. 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, overtemperature) 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.

  • The +Out and –Out power buses should be designed to minimize and balance parasitic impedance from each module output to the load.
  • The +Sense pins must be tied together to form a +Sense bus. This must be Kelvin connected to +Out at a single point. The –Sense pins should be tied together to form a –Sense bus. This must be Kelvin connected to –Out at a single point.
  • At the discretion of the power system designer, a subset of all modules within an array may be configured as slaves by connecting SC to –S.
  • OR’ing diodes may be inserted in series with the +Out pins of each module to provide module output fault tolerance.
  • The +Sense and -Sense leads should be routed in close proximity to each other on the printed circuit board. If wires are used to connect the converters on a PCB to an external load, the Sense leads should be twisted together to reduce noise pickup.
