Admonishments

Important safety admonishments are used throughout this manual to warn of possible hazards
to persons or equipment. An admonishment identifies a possible hazard and then explains
what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use
of the triangular safety icon (seen below), and are listed in descending order of severity of
injury or damage and likelihood of occurrence.

Danger:

injury, death, or substantial property damage if the hazard is not avoided.

Warning:

personal injury, death, or substantial property damage if the hazard is not avoided.

Caution:

personal injury or property damage if the hazard is not avoided.

1. GENERAL

The DMPS-10CE Power Supply, as shown in Figure 1, is a rack mounted power supply
providing +5, +12, and –12 Volts dc. It is expandable (with the basic power supply and up to
three DMPS-10EXP/CE expansion modules) to a total of four dc power sources each
providing + 5, + 12 and –12 volts.

DMPS-10CE POWER SUPPLY

The power supply including the basic unit measures 3.5  19  11 inches (8.9  48.3  27.94
cm). Each DMPS-l0EXP/CE expansion module measures 3.5  3.9  9.22 inches (8.9  9.91

23.5 cm) and fits into the basic power supply.

The DMPS-10CE has EN 60950 classification for use in Europe.

2. DETAILED DESCRIPTION

2.1 DMPS-10CE Power Supply (Basic)

The DMPS-10CE power supply is designed for the ADC Telecommunications PatchSwitch
system but will work well with other applications. It will operate with any input voltage
between 190 and 240 volts ac and any frequency between 48 and 62 Hz. Manual adjustments
are not necessary. Only one ac input is necessary per shelf for up to four dc power sources (the
basic unit plus three expansion modules).

Input ac power is supplied via a six-foot, three-conductor power cord equipped with a
standard three prong with ground plug on one end and a special IEC 3-pin connector on the
other. The special IEC 3-pin connector plugs into the back of the basic DMPS-l0CE power
supply. Fuses are installed at the factory as described in “Power-Up of the DMPS-l0CE Power
Supply” section, page 6 of this manual.

There are four LED indicator lights on the front of the unit to indicate whether the power
supply and expansion modules are operating. The right-most LED (marked “DC OUT 1”) is
for the basic unit. Each of the three others (marked DC OUT 2, 3 & 4) displays the condition
of the expansion modules.

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 self­contained 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

ADCP-50-404 • Issue 2 • November 1998

+12 Vdc ± 10% for 0 to 1.0 Amps
–12 Vdc ± 10% for 0 to 0.5 Amps
