1. Description
The LPM409 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 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 are needed, the supply's four slots can
be configured with PCB-based output modules to deliver up to four 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
85 VAC input. Forced-air cooling with airflow direction from front to back 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 se ttings prior to delivery. The LPM409 chassis can be populated with the output
modules listed in Table 1 .
