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. T he 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 a n 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.

1 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. 2 For the power derating specification please see section 1.4 below. 3 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.

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. 3.1.

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 Figure 15 (especially all pins 3 - CSH and all pins 4 - Common must be reconnected). 3 Modules K-N cannot be connected in parallel.

© 2015 Bel Power Solutions, Inc. 866.513.2839 tech.support@psbel.com BCD.00365_AB3 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.
