Example: After entering your requirements, the web Configurator could recommend the following optimized part

number: LPM409-0HEG-DXXX which represents: Low Profile Modular Series with single-phase AC input, 4-slot, 900W

chassis with modules of: blank panel “0” in slot 1 and modules H, E, G in slots 2 to 4, respectively. 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.
