2.1.1 General
1.
Source voltage DC input points (+IN, –IN): Designed to accommodate #10 hardware and
Panduit ring lugs. The PRM has no reverse power protection so be sure to observe correct
polarity.
2.
Toggling switch (SW01): Used to enable or disable the PRM. The ON position enables the
PRM by allowing the PRM PC pin to float. The OFF position disables the PRM by pulling
the PRM PC to signal ground (SG).
3.
Toggling switch (SW02): Used to open or close the connection between the reference
voltage produced from the potentiometer (R10) and the positive input of the comparator
op amp. This is provided as an added feature to allow the use of an external shunt
regulator. The recommended component is TLV431B. For further details refer to application
note
Make sure to turn this switch to the "open" position when a shunt regulator is in use.
4.
Output voltage points (+OUT, –OUT).
5.
Output connector (J01): Used for mating with VTM-CB providing V
OUT
and VC. As shown
dedicated to the +OUT, four for the –OUT, and two for the VC. Each contact is rated for
3 A. The excess capacity afforded by these pins can facilitate testing multiple VTM-CBs
from a single PRM-CC using appropriate wiring harness and mating connector. This may
also be achieved using the large pads of the output voltage points.
