TEMP_OK
TTL compatible Logic HIGH provided when the temperature is within the allowable range of operation.
Internally connected to GND; when the power module is correctly seated the corresponding mating

This is the shortest “last make, first break” (last to mate in the sequence).
If left open circuit then the main output will be inhibited (no output).
PS_INHIBIT/PS_KILL
When inserted in to the system slot this pin must be pulled “low” by the system to enable (turn on) the
Main output and only after all other pins are connected and the power module is correctly seated.

CURRENT SHARING NOTES
1. Main 12VDC Output: Analogue active share bus. The ISHARE bus (Pin B3) must be connected on all sharing modules. It is not required that the SENSE signals are connected to the remote load for current share
to operate correctly.
2. Up to eight (8) power modules can be connected in parallel (non-redundant) or N+1 configuration. The current share bus is analogue bi-directional (can source or sink current from the ISHARE bus). The voltage
of the bus would measure 8VDC for a single power module at 100% load; for two (2) modules sharing a common load the ISHARE bus voltage would be 4V for a perfect 50/50 current share scenario.
3. VSTANDBY output power modules can also be connected in parallel and have internal output isolation devices; however the combined available power is limited to that available from a single power module
(3.3V or 5V; 20W) irrespective of the number of modules connected in parallel.
