LPM616 AC-DC Modular Power Supply Data Sheet
5V, 12V, 24V & 48V Single-Output Modules
1. Description
The LPM616 Series is a modular 1600-watt AC-DC power supply that provides a market-leading power density of
18 watts per cubic inch and has an extra low 1U profile. The LPM616 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 six slots can be
configured with PCB-based output modules to deliver up to six outputs. The LPM output modules operate in any
chassis position and can provide up to 1600 watts total power from a 150 VAC input and 1300 watts from a
100 VAC input. Forced-air cooling with airflow direction from front to back is provided by internal fans.
For LPM616 supplies using less than the six-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 LPM616 chassis can be populated with the output
modules listed in Table 1.

NOTE 1: To determine your desired power supply's part number, please refer to Figure 2 for a detailed part number
description. Use the LPM616 Product Configurator located in the Modular Section on our website, or use our contacts page
to locate a contact or distributor for further assistance.
NOTE 2: Values given for high line, from 150 VAC. By low line is the module output power derated to 183 W (Vin=85-100VAC),
resp. 217 W (Vin=100-150VAC).
1.1 Output Voltage and Current Limit Adjustments
Each LPM616 module’s output voltage and current limit is adjustable by means of a trimmer located on the
module and accessible through the adjustment holes located on the bottom of the power supply (see Figure 10).
We dissuade to change current limits, which are factory preset.
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. For proper current sharing function it is necessary to interconnect Current Share pins of all
modules by signal wires. For more details read the Output Signal Connector and Accessories section.

2. Part Numbering and Ordering Information
2.1 Chassis Identification Numbering
First left-to-right sequence of the part number (4 characters):
• LPM616 ..... Low Profile Modular 6-slot, 1600W, with single-phase AC input. (see Figure 2)
Note: Chassis and modules are RoHS-6 compliant.
Figure 2. LPM 6-Slot Part Number Structure
Example: After entering your requirements, the web Configurator optimized part number recommended could be:
LPM616-000DAC-DXXX which represents: Low Profile Modular Series with single-phase AC input, 6-slot, 1600W
chassis with modules of: 3x blank panel, modules D, A, C in slots 1 to 6, respectively. Besides the blank panels in
slots 1-3, the example's modules in this case would represent desired DC output voltages as follows: Slot 4 = D for
48V, Slot 5 = A for 3.3V and Slot 6 = C for 24V.
Assembly facility code and customer build ID No. are established during actual power supply assembly.

Notes:
1
For load current over 250A use two of LPM000-BBAR-01 and two cables for each pole.
2
by using busbars (paralleling modules) you will need also the signal output leads LPM000-LEAD-02, one for each module
connected by the same busbar . The interconnection is shown in Fig.16 (especially all pins 4 - CS and all pins 2,7 – SGND
must be reconnected).

Note that for 300A output current (LPM616-AAAAAA-DXXX on Figure 14 ) this is the most preferred arrangement
to achieve the best thermal flow. Connect two power cables for each pole (2x70mm
2
). Use 105°C thermal class
isolation.
