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. 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 Standard output voltages of 1.5 to 54 VDC density. Efficiencies up to 87% typical Designed for use where a unique set of voltage and Extra-Low 1U profile: 1.6 inch current requirements is needed, the supply s four High power density design of 14 Watts/cubic inch slots can be configured with PCB-based output 1 to 4 isolated output slots, fully user configurable Power Factor Correction (PFC) IEC 61000-3-2 compliant modules to deliver up to eight outputs. The LPM 700W 85 VAC or 900W 150VAC of total output power output modules operate in any chassis position and Zero-load operation can provide up to 900 watts total power from a 150 Single-wire current sharing VAC input and 700 watts from an 85 VAC input. Universal input AC range Forced-air cooling with airflow direction from input to Individual control signals on each module output is provided by an internal fan. Auxiliary power 5V (1A) 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 LPM409 (Industrial) LMM409 (Medical) settings or with the customers desired output Industrial equipment Imaging Equipment settings prior to delivery. Telecommunications Anesthesiology The LPM409 chassis can be populated with the Test and measurement Surgical Devices output modules listed in Module Selection table.

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 modules 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 modules 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. 866.513.2839 tech.support psbel.com 2015 Bel Power Solutions, Inc.
