Connector Descriptions
Output Terminals
The NI PS-12 and NI PS-13 have a total of four output terminals, providing two positive (+)
output terminals and two negative (-) output terminals. Both positive terminals are wired
together internally, and both negative terminals are wired together internally.
Input Terminals
The NI PS-12/13 power supply derives power through the input terminals on the front panel.
There are three terminals corresponding to the Neutral input, the Line (or hot) input, and the
Protective Earth (PE) input. The NI PS-12/13 rectifies both single-phase and two-phase AC
input. The Neutral input terminal provides a MAINS return path for the input circuitry. The Line
input is the primary power input for the supply. The PE input corresponds to an earth ground.
The power supply case itself is grounded to the PE input.
Caution
for proper operation of the NI PS-12/13.
