LPM / LMM409 Series AC—DC Modular Power Supply 5, 10. 12, 20, 24, 36 & 48 V Single-Output Modules 10 & 20 V Dual-Output Modules Applications Key Features & Beneﬁts POWER . b—el sownonss PROTECTION a bet group belfuse.com/power—solutions

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 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.

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 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

200 V. 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.

PFAIL open or High state indicates the warning that the input is out of limits (the input voltage

falls below 85 VAC or rises over 264 VAC) 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.

Fan Fail / OTP Indication

- FAN_FAIL -

Open Collector output pin with 20 mA pull-down capability referenced to logic return RTN_D.

FAN_FAIL OPEN OR HIGH state indicates a fan failure/over temperature protection (OTP)

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 100 A 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.

The example of LPM409-0000EE-DXXX assembly configuration (two modules in parallel) is shown in

Figure 13

One set of busbars LPM000-BBAR-07 + 2x LPM-LEAD-04 are necessary for connection.

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 200 A output current

(LPM409-EEEE-DXXX) connect minimal two power cables for each pole (2x 42 mm2 for one pole).

Use min. 105°C thermal class isolation.
