The CP2000DC54-PE DC/DC Converter, also called a Power Entry Module (PEM)
in the Compact
Power Line platform is specifically designed to operate as an integral part of a complete distributed power
system. The high-density, front-to-back airflow PEM is designed for minimal space utilization and is highly
expandable for future growth. It is provided with many features including PoE isolation, and dual-
redundant I
2
C communications busses that allow it to be used in a broad range of applications. The
flexible feature set makes this Power Entry Module an excellent choice for applications requiring modular
dc-to-dc bulk intermediate voltages, such as in distributed power.

Hiccup performance attempts automatic recovery from an overload shutdown with approximately a 90% off-time duty cycle. The
duty cycle varies periodically in order to guarantee multi-module recovery synchronization. Latchoff can be chosen via software
instead of the default hiccup. Recovery from a latchoff requires ENABLING, or software commanding OFF followed by an ON
after a 2 second delay.

Status and Control
The PEM provides two means for monitor/control:
analog or I
2
C.
Details of analog controls are provided in this data
sheet under Signal Definitions. Lineage Power will
provide separate application notes on the I
2
C
protocol for users to interface to the CPL PEMs.
Contact your local Lineage Power representative
for details.
Software commanded margining overrides the
hardware set point indefinitely or until the default
setting is reinstated for example if input power and
bias power have been removed from the module.
Module Present Signal:
The power supply alerts
the system when it is properly plugged in via a
500Ω resistor in series between this signal and
Logic GRD.
Protocol Select:
This pin must remain a no-
connect. Do not connect to either output or
Logic_GRD.
Enable:
On/Off control when I
2
C communications
are utilized as configured by the Protocol pin. This
pin must be pulled low to turn
ON
the power
supply. The power supply will turn
OFF
if either the
Enable
or the
ON/OFF
pin is released. This signal
is referenced to Logic_GRD.
ON/OFF:
This is a short pin utilized for hot-plug
applications to ensure that the power supply turns
OFF
before the power pins are disengaged. It also
ensures that the power supply turns
ON
only after
the power pins have been engaged. Must be
connected to V_OUT (-DC).
Hot Plug
When rapidly extracting and reinserting modules
care should be taken to allow for discharging the
internal bias supply so that a predictable restart
could be achieved. The way to ensure that the
circuit sufficiently discharges is to observe the
spinning of the fans after an extraction. The unit
should not be reinserted until the fans stop
spinning.
Without bleeding down internal bias the module
may remember its last assigned address and may
not configure itself properly if reinserted into
another slot.
Control Definitions
All signals are referenced to Logic_GRD unless
otherwise noted. See the Signal Definitions Table
at the end of this document for further description
of all the signals.
Output Signals
Power_OK:
This signal is HI when the main output
is present and goes LO when the main output is not
present.
I_limit:
This signal is HI when the main output is
not in current limit and goes LO when current limit
has activated.
Alert #:
I
2
C interrupt signal.
Fault:
This signal goes LO for any failure that
requires PEM replacement. Some of these faults
may be due to:
Fan failure
Over-temperature condition
Over-temperature shutdown
Over-voltage shutdown
Internal PEM Fault
Input Signals
Margining:
Set point of the PEM can be changed
via this input pin. Programming can be either a
voltage source or a resistance divider. The
margining pin is connected to 3.3Vdc via a 10kΩ
resistor inside the PEM. See graphs below.
