b) Power Limit: Output power is limited to 3500W.
c) Over Temperature Protection: The operation of a DC-DC converter will automatically shut down
and lock out if the internal temperature of the module exceeds a predetermined value. Operation
will automatically resume after the over-temperature condition is corrected.
•Series Paralleling Output FET: A series paralleling output FET is provided in each DC-DC converter.
This allows the modules to be paralleled for redundancy.
•Hot Swappable: The converter is designed to be plug-and-play. The converter can be inserted or
removed from a live DC power system with no damage. When the converter is plugged into the system,
the system output voltage will not be affected.
•Cooling: Each converter contains a fan for forced convection cooling.
a) Fan Fault Protection: The converter shuts down and its alarm indicator (red) flashes if the fan fails.
Fan failure is detected and reported to controller. The fan is field replaceable.
b) Fan Control: Fan speed is continuously variable. When input voltage is within normal range, the
built-in processor adjusts fan speed according to the converter’s output power. For example, a
higher output power increases the fan speed.
•Communication Failure: The protection indicator (yellow) will flash should communication between the
converter and associated system controller fail. The failure information will be reported to the
associated system controller and the controller will process the failure accordingly. During a
communication failure, the converter output voltage will automatically adjust to 48.00Vdc. The
converter will revert to normal operation once normal communication is restored.
•Monitoring Function: The converter has a built-in advanced DSP (Digital Signal Processor) that
monitors and controls the operation of the converter. The DSP also communicates with the associated

•Interval Start Function: The time period between starting each converter in the system can be set via
controller. It reduces the inrush current which draw from the 400V power and improve the stabilization
of the whole system.
•Power Derating Based on Temperature: The converter delivers full power when operating at an ambient
temperature of +45°C (+113°F) or below. Each converter continuously monitors the ambient
temperature surrounding the power conversion circuit. If this temperature for any reason (such as a
high ambient temperature or failed fan) increase above approximately +45°C (+113°F), the converter will
not shut down. Rather, the converter limits its maximum output power to maintain the temperature of
the power conversion circuit within design parameters. Operation between +45°C (+113°F) and +75°C
(+158°F) will result in output power being decreased. Full power capability is restored when the
temperature decreases to below approximately +45°C (+113°F). Refer to Figure 1to review the
relationship between the output power and the ambient temperature.

WARNING! The module is rated for continuous operation at full output power up to +45°C (+113°F).
Operation between +45°C (+113°F) and +75°C (158°F) will result in output power decreasing. Operation
above +75°C (+158°F) is considered abnormal and should be used on a temporary1 basis only.
1Temporary Operation at Abnormal Temperature: Temporary operation refers to a period of not
more than eight consecutive hours per day, and a total of not more than 15 days in a year. (This
refers to a total of 120 hours in any given year, but no more than 15 occurrences in that one year
period.)

Replacement Procedures
Converter Module Replacement
Converter modules can be inserted or removed with power applied (hot swappable).
NOTE! Each converter locks into a module mounting shelf by means of a latch located on the underside
of the converter module. The latch and converter module handle are interactive. Push the handle into
the converter module’s front panel, and the latch will pop out from the converter module bottom. Click
the handle to pop it out from the converter module’s front panel, and the latch will retract back into the
converter module. The latch mechanism is shown in Figure 3 .
DANGER! Take care when removing a converter that was in operation, as converter surfaces could be
very hot.
WARNING! To prevent damage to the latching mechanism, ensure the converter module handle is in
the open position when installing or removing a converter module. NEVER hold the handle in the closed
position when installing a converter into a shelf.
Procedure
NOTE! Refer to Figure 3 as this procedure is performed.
1. Performing this procedure may activate external alarms. Do one of the following. If possible, disable
these alarms. If these alarms cannot be easily disabled, notify the appropriate personnel to disregard
any alarms associated with this system while this procedure is performed.
2. On the converter module to be removed, push the converter module handle in and release in order to
pop it forwards out of the converter module’s front panel (this will also retract the latch mechanism
located on the underside of the converter module). Refer to Figure 3.
3. Slide the converter out by pulling forwards.
4. Place the replacement converter module into the mounting position without sliding it in completely.
5. On the replacement converter module, push the converter module handle in and release in order to pop
it forwards out of the converter module’s front panel (this will also retract the latch mechanism located
on the underside of the converter module). Refer to Figure 3.
6. Push the converter module completely into the shelf.
7. Push the handle into the front panel of the converter module. This will also cause the latch mechanism
located on the underside of the converter module to lock the converter module securely to the shelf.
8. Certain functions (i.e. converter current limit, converter addressing) may require adjustment when
adding or replacing a converter module. Refer to the power system documentation for instructions.
9. After the converter modules are physically installed in the mounting shelf(s), they are ready for
operation immediately after power is supplied to them. Verify that the converter modules are operating
normally.
10. Enable the external alarms, or notify appropriate personnel that this procedure is finished.
11. Ensure that there are no local or remote alarms active on the system.
