DESCRIPTION
11 100-127V ~ 50/60Hz 16A,
200-240V ~ 50/60Hz 8A
(2 [DM-MD64X64] or 3 [DM-
MD128X128])
IEC 60320 C-20 main power inlets;
Mate with removable power cords
(included)

12 POWER SUPPLY
(1-2 or 1-3)
(2 [DM-MD64X64] or 3 [DM-MD128X128])
High efficiency (>90%), hot-swappable,
variable speed fan cooled power supplies,
Crestron model DM-MDA-64-PWS
(included with DM-MD64X64) and
DM-MDA-128-PWS (included with
DM-MD128X128);
Demonstrated MTBF: >500,000 hours per
power supply;
Redundancy: Complete unit continues to
operate at full capacity on one
(DM-MD64X64) or two (DM-MD128X128)
functioning power supplies
1
13 OK LEDs (2 [DM-MD64X64] or 3 [DM-MD128X128])
Green LEDs, indicate when each
corresponding power supply is powered
and functioning:
• Blinking green indicates that ac power
is being applied and standby output
voltage is available.
• Solid green indicates that dc output is
enabled and operational.
14 ! LEDs (2 [DM-MD64X64] or 3 [DM-MD128X128])
Amber LEDs, each indicates a fault with
the corresponding power supply:
• Solid amber indicates power supply
failure or overcurrent protection of
standby voltage.
• Blinking amber indicates overcurrent
protection of the main circuit.
15 G (1) 6-32 screw, chassis ground lug
1. Although the DM-MD64X64 and DM-MD128X128 continue to operate if a single power supply fails,
it is recommended that the failed power supply be replaced as soon as possible to restore power
supply redundancy.
2. All power inputs on the DM switchers must connect to the same ac voltage type—either 120 Vac or
220 Vac.
