1. Description
The LPM/LMM409 Series is a modular 900-watt AC-DC power supply that provides a market-leading power
density of 14 watts per cubic inch and has an extra low 1U profile. LMM is medically approved version. Further will
be discussed only LPM version and differences of LMM 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 are needed, the supply's four slots can
be configured with PCB-based output modules to deliver up to four 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 a
85 VAC input. Forced-air cooling with airflow direction from front to back 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 Table 1.

To determine your desired power supply's part number, please refer to Fig.3 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. (http://lpm.power-one.com/cgi-bin/start.cgi/lpm/config_start.html)

For the power derating specification please see section 1.4 below.
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
(see Fig.11). For the modules K<->N the trimmer is accessible from rear side of the power supply (see Fig.6).
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 the connections requiring
higher current needs. To ensure the current sharing function works correctly it is required to interconnect the
signal pins of the modules that will operate in parallel. Only E-J modules can be connected in parallel. For more
details read section 10.3 and Fig.17.
1.3 Serial Connections
To increase the output voltage it is possible to connect modules in series. Serial busbars are available (see
section 10.4) to make the 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. The maximal total voltage must not
exceed 200V. PowerOne recommends to only connect the same modules with the same current rating in series.
The voltage sense pins VS+, VS- available on LM126 modules must be connected according to Fig.18.

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 the Fig.2.

First left-to-right sequence of the part number (4 characters):
• LPM409 .. Low Profile Modular 4-slot, 900W, with single-phase AC input. (see Fig.3)
Note: Chassis and modules are RoHS-6 compliant.
Fig.3 LPM 4-Slot model part number description
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” and modules H, E, G in slots 1 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 1-4 is from the left to right when looking from the rear.

10. Accessories
10.1 Mating Connections and Cables
All the power and signal cables and mating connectors are not included in the LPM409 standard package. These
all need to be ordered extra.
• Front panel signal cable: Power-One accessory LPM000-LEAD-03, see Fig.12
• Output signal cable: Power-One accessory LPM000-LEAD-04, see Fig.13a
mating connector: JST, housing PHDR-10VS, pins SPHD-002T-P0.5 (AWG 28-24)
• Output power cable (for LPM126): 14AWG – 10AWG depend on the output current, min. thermal
class 105°C, lug terminal 4mm 6mm
2
• Output power cable (for LPM109/118): Power-One accessory LPM000-LEAD-05, see Fig.13b

10.3 Paralleling Busbars (only for modules E-J)
Item Description
Model
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 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 Fig.17 (especially all pins 3 - CSH and all pins 4 - Common must be
reconnected).
3
Modules K-N cannot be connected in parallel.
The example of LPM409-00EE-DXXX assembly configuration (two modules in parallel) is on Fig.14. One set of
busbars LPM000-BBAR-07 + 2x LPM-LEAD-04 is necessary for connection.
Fig.14 LPM409-00EE-DXXX Parallel Configuration Fig.15 LPM409-0EEE-DXXX Parallel Configuration
An example of an LPM409-0EEE-DXXX assembly configuration (three modules in parallel) is on Fig.15. Two sets
of busbars LPM000-BBAR-07 + one set of LPM000-BBAR-08 + 3x LPM-LEAD-04 are necessary to make the
interconnections.
Note, that 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 in case of higher output currents, more output cables must be used for each pole. For
example for 200A output current (LPM409-EEEE-DXXX) connect minimal two power cables for each pole (2x
42mm
2
for one pole). Use min. 105°C thermal class isolation.
