The LPM/LMM409 Series is a modular 900-watt ACDC power supply that provides a market-leading
power density of 14 watts per cubic inch and has an
extra low 1U profile. The LMM is the medically
approved version. From here on only the LPM
version will be discussed, differences for the LMM
version will be noted. The LPM409 offers the
flexibility of a modular architecture and the
combination of high efficiency and high power
density.
Designed for use where a unique set of voltage and
current requirements is needed, the supply's four
slots can be configured with PCB-based output
modules to deliver up to eight outputs. The LPM
output modules operate in any chassis position and
can provide up to 900 watts total power from a 150
VAC input and 700 watts from an 85 VAC input.
Forced-air cooling with airflow direction from input to
output is provided by an internal fan.
For LPM409 supplies using less than the four-slot
capability, blanking plates are installed for safety
purposes and to optimize airflow within the chassis.
The supplies are pre-set with default output module
settings or with the customer’s desired output
settings prior to delivery.
The LPM409 chassis can be populated with the
output modules listed in Module Selection table.
Conformal coating is available on request, please
consult with the factory.

To determine your desired power supply's part number, please refer to Figure 2 for a detailed part number description.
Use the LPM Configurator located in the Modular Section on our website, or use our contacts page to locate a
distributor for further assistance.
For the power derating specification please see section 1.4 below.
Add –C for Conformal coating option.
1.1. Output Voltage Adjustment
Each LPM409 module’s output voltage is adjustable by means of a trimmer located on the module. For the modules
E<->J the trimmer is accessible through the adjustment hole located on the bottom of the power supply (Figure 10).
For the modules K<->N the trimmer is accessible from rear side of the power supply (Figure 5).
1.2. Parallel Connections
Depending on certain situations where current requirements exceed one module’s capability, the configurator will
process a solution using parallel connections. Paralleling busbars are available to make connections requiring higher
current needs. For correct current sharing functionality it is necessary to interconnect Current Share pins of the
modules that will operate in parallel using signal wires. Only E-J modules can be connected in parallel. For more
details read section 10.3, see Figure 15.
1.3. Serial Connections
To increase output voltage it is possible to connect modules in series. Serial busbars are available (see section 10.4)
to make connections requiring higher voltage needs. The output of LPM409 is rated as SELV circuit, so the output
voltages are guaranteed to be less than 60V. The series combination of modules can exceed this SELV voltage, so in
this case the users must take adequate precautions to prevent direct contact with conductive parts. The maximal
total voltage must not exceed 200V. It is recommended to only connect the same modules with the same current
rating in series. The voltage sense pins VS+, VS- available on LPM126 modules must be connected according to
Figure17.
1.4. Power Derating
When specifying an LPM409 power supply in an application it is necessary to ensure that LPM409-CHAS and
modules (LPM126, LPM118 and LPM109) are operating within their power output capabilities, taking into account
the temperature derating and input voltage derating. The maximum permissible output power that may be drawn
from LPM409-CHAS and modules assembled in this chassis is given in Figure1.

Example: After entering your requirements, the web Configurator could recommend the following optimized part
number: LPM409-0HEG-DXXX which represents: Low Profile Modular Series with single-phase AC input, 4-slot, 900W
chassis with modules of: blank panel “0” in slot 1 and modules H, E, G in slots 2 to 4, respectively. Besides the blanking
panel in slots 1, the example's modules in this case would represent desired DC output voltages as follows: Slot 2 = H
for 36V, Slot 3 = E for 3.3V and Slot 4 = G for 24V.
Assembly facility code and customer build ID No. are established during actual power supply assembly.
The slots numbering when viewing the unit from the rear, or output side is 1 - 6 from left to right.

Open Collector output with 20mA pull-down capability referenced to logic return RTN_D.
PFAIL open or High state indicates the warning that the input is out of limits (the input
voltage falls below 85Vac or rises over 264Vac ) 5 ms before the output goes below the
lower regulation limit. PFAIL will turn-off the green Input OK LED.
PFAIL LOW state indicates that the input voltage is within the operating range.

Paralleling Busbars (only for modules E-J)
ITEM
DESCRIPTION
LPM000-BBAR-07
Busbar for parallel connection of two modules, central screw M5, max. 100A 1.
Two pieces are in one package LPM000-BBAR-07.
LPM000-BBAR-08
MODEL
Busbar washer with 1 opening for odd module paralleling.
Two pieces are in one package LPM000-BBAR-08.
NOTES:
1
For load current over 100A use two or more cables connected to separate busbars.
2
By using busbars (paralleling modules) you will need also the signal output leads LPM000-LEAD-04, one for each connected module.
The interconnection is shown in Figure 15 (especially all pins 3 - CSH and all pins 4 - Common must be reconnected).
3
Modules K-N cannot be connected in parallel.

LPM/LMM409
The example of LPM409-00EE-DXXX assembly configuration (two modules in parallel) is shown in Figure13. One set of
busbars LPM000-BBAR-07 + 2x LPM-LEAD-04 is necessary for connection.
Figure 13 – LPM409-0000EE-DXXX Parallel Configuration
Figure 14 – LPM409-000EEE-DXXX Parallel Configuration
An example of an LPM409-0EEE-DXXX assembly configuration (three modules in parallel) is in Figure14. Two sets of
busbars LPM000-BBAR-07 + one set of LPM000-BBAR-08 + 3x LPM-LEAD-04 are necessary to make the
interconnections.
Note, for odd number of modules in parallel it is necessary to also use one set of busbar washers LPM000-BBAR-08.
To connect the load for higher output currents use more cables for each pole. For example for 200A output current
(LPM409-EEEE-DXXX) connect minimal two power cables for each pole (2x 42mm2 for one pole). Use min. 105°C
thermal class isolation.
