To determine your desired power supply's part number, please refer to

Use the LPM Configurator located in the Modular Section on our website, or use our contacts page to locate a

distributor for further assistance.

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

(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.
