PFD output is an open collector which will

sink ≤ 40 mA in the low state.

Mechanical Notes

A Metallic or non-metallic stand-offs (maximum diameter 5.4 mm) can

be used in all four mounting holes without effecting safety approval.

B The ground pad of the mounting hole near J1, allows system

grounding through a metal stand-off to the system chassis.

C The heat sink is grounded, and allows system grounding by

mechanical connection to the system chassis.

D The supply must be mechanically supported using the PCB

mounting holes and may be additionally supported by the heatsink

mounting holes.

E It is always advisable to attach the power supply heat sink to

another thermal dissipator (such as a chassis or finned heatsink

etc). The resulting decrease in heat sink mounted component

temperatures will improve power supply lifetime.

F A standard L-bracket and cover is available for mounting which

contains all screws, connectors and necessary mounting hardware.

The kit is available, order part number “NFS110CJ”.
