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 a 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.
