3. DMPS-10EXP/CE EXPANSION MODULE
The DMPS-l0EXP/CE Expansion Module, as shown in Figure 2, is designed to be installed
into the DMPS-10CE Basic Power Supply as dc power requirements expand at an installation.
The expansion module receives ac power from the basic shelf and is a completely self-
contained power supply in all other respects.
Up to three expansion modules can be mounted into the DMPS-l0CE Power Supply shelf. The
shelf requires a single ac power source (190 to 240 Vac, 48 to 62 Hz) to deliver up to 4 dc
outputs (via 9-pin cable connectors), each output supplying +5 Vdc, +12 Vdc and –12 Vdc.
Any input voltage between 190 and 240 volts ac can be accommodated without adjustment to
the power supply.
Outputs available from each of the modules (basic plus expansion modules) are +5 Vdc at up
to 4.5 Amps, +12 Vdc at up to 1.0 Amp, and –12 Vdc at up to 0.5 Amp.
Regulation is maintained on the respective voltages, keeping them constant to the tolerances
shown for the given current ranges:
+5 Vdc ± 5.0% for 0 to 4.5 Amps
+12 Vdc ± 10% for 0 to 1.0 Amps
–12 Vdc ± 10% for 0 to 0.5 Amps
