The Transition Networks SPS-1872-xx external power supply provides a wide range
of input power (18-60 VDC and 24-30 VRMS) to accommodate most industrial,
telecom, and commercial applications. The SPS-1872-xx can deliver 12 watts of
power, enough to power all Transition Networks stand-alone media converters as
well as the single-slot (p/n CPSMC0100-20x) and the dual-slot (p/n CPSMC0200-2xx)
chassis.
The 18-60 VDC input allows for the installation of the SPS-1872-xx external power
supply in all popular telecom, commercial, and industrial applications. The 24-30
VRMS input allows for installation of the SPS-1872-xx in remaining industrial
applications as well as HVAC and building control environments.
The 'piggy-back' feature of the SPS-1872-CC, SPS-1872-PS, and SPS-1872-DPS
allows it to physically attach to the media converter chassis and eliminate the power
cable between the power supply and the media converter.

Maintenance
Supplying Power to the SPS-1872-xx
Replacing the Fuse
CAUTION: The power source MUST BE TURNED OFF when connecting it to
the SPS-1872-xx external power supply. Failure to observe this caution could
result in damage to, and subsequent failure of, the SPS-1872-xx and any attached
device.
CAUTION: The external power source MUST BE POWERED OFF when
replacing the fuse to the SPS-1872-xx external power supply. Failure to observe
this caution could result in damage to, and subsequent failure of, the SPS-1872-
xx and any attached device.
To supply power to the SPS-1872-xx:
NOTE: Replace the fuse only with one of the same size and rating.
1. Ensure that external power source is truned OFF.
To replace the fuse in the SPS-1872-xx external power supply:
1. Ensure that the external power source is turned OFF.
2. Connect the positive (+) terminal of the power source to the positive
terminal on the SPS-1872-xx (marked with a “3”). Turn the terminal
screw clockwise to secure it.
2. Remove and retain the four (4) screws that secure the cover to the SPS-
1872-xx external power supply.
3. Connect the negative (-) terminal of the power source to the negative
terminal on the SPS-1872-xx (marked with a “2”). Turn the terminal
screw clockwise to secure.
3. Carefully lift the cover from the SPS-1872-xx.
4. Locate the fuse on the SPS-1872-xx (see the picture below).
4. Connect the ground terminal of the power source to the ground terminal
on the SPS-1872-xx (marked with a “1”). Turn the terminal screw
clockwise to secure.
5. Power on the external power source.
WARNING: The SPS1872 must be attached to a limited current circuit with a
non-hazardous energy level of less than 240VA and be located in a restricted
access area. Failure to observe this warning could result in an electrical shock.
5. Carefully remove the fuse the from the fuse holder.
6. Install a same size and rating replacement fuse in the fuse holder.
7. Carefully slide the cover onto the SPS-1872-xx.
