Power Output
DC Power is available form 3 sources.
o
“
PWR
” – derived from the input source (and isolated from EXT
and COMMS):
When input source is
AC
mains, a DC output of 28V (
±
5%) is
factory set with potential to be increased up to 36V (
±
5%) by
internal PSU adjustments.
When input source is
DC
then the DC output will be 1.5V less
than the DC Input supply.
If both supplies are connected, the greater voltage will be used.
Rated at 50W or 2A max.
Fused internally with a 20mm
×
5mm 2A 250V “Quick Acting”
(F) Fuse.
o
“
EXT
” – internally derived (and isolated from PWR and
COMMS), +12V or +5V supply for optional peripheral power.
Rated at 15W max.
Fused internally at 2A, with thermal shut-down.
o
“
COMMS
” – internally derived (and isolated from PWR and
EXT), +5V supply for communication signals.
Rated at 1W max
Short circuit protected for 1s maximum.
DC Power output available on rear ports (refer to power supply section
for further details regarding isolation barriers and grounding options)…
o
“Port C” and “Port D” – PWR source
o
“AIF (ArcNet)” – output is selectable from PWR, EXT or
COMMS
o
4mm Power Output Sockets – output is selectable from PWR,
EXT or COMMS
Current drawn from the outputs should not exceed the greater of 50W or
2Amps in total.
