1. Designed to start at an ambient as low as -40°C, but may not meet operational limits until above -5°C.
2. Power derating shall consider only temperature variations at nominal line (100 – 120, 200 – 240Vrms). The unit may derate
faster if the input line is below nominal.
3. Class B radiated emmissions compliance requires the addition of a ferrite bead to each power line cord at the shelf-end of the
cable. See the figure below.
4. Radiated emissions compliance was met using a Lineage Power shelf. This shelf includes output common and differential mode
capacitors that assist in meeting compliance.

Status and Control
The rectifier provides three means for
monitor/control: analog, PMBus compliant I
2
C, or
RS485 for interfacing to Lineage Power controllers
or battery plants.
Details of analog controls are provided in this data
sheet under Signal Definitions. Lineage Power will
provide separate application notes on PMBus
protocol for users to interface to the CPL rectifiers.
Contact your local Lineage Power representative
for details.
Module Present Signal:
This signal has dual
functionality. It can be used to alert the system
when a module is inserted. Has a 500Ω resistor in
series between this signal and Logic GRD. An
external pull-up should not raise the voltage on the
pin above 0.25Vdc. If raised the pin is raised to
5Vdc the write_protect feature of the EEPROM is
enabled.
Protocol Select:
Establishes the communications
mode of the power supply, between analog/I
2
C and
RS485 modes. For RS485, connect 750 – 3.92kΩ
pull-down resistor to 54_OUT(-DC).
Enable:
On/Off control when either PMBus
communications or analog functions are utilized as
configured by the Protocol pin. This pin must be
pulled low to turn
ON
the main output of the power
supply. The power supply will turn
OFF
if either the
Enable
or the
ON/OFF
pin is released. The
Enable
function does not work with the RS-485 protocol.
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 54_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.
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.
Input Signals
Margining:
Setpoint of the rectifier 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 rectifier. See graphs below.
Output Signals
Alert #:
PMBus interrupt signal.
Fault:
This signal goes LO for any failure that
requires rectifier replacement. Some of these faults
may be due to:
•
Fan failure
•
Over-temperature condition
•
Over-temperature shutdown
•
Over-voltage shutdown
•
Internal Rectifier Fault
Power Capacity:
A HI on this pin indicates rectifier
configured for 2000W operation; a LO indicates
rectifier configured for 1200W operation.
An open circuit on this pin reverts the voltage level
back to the original setting.
