low voltage multi-output power supply module
LOW VOLTAGE MULTI-OUTPUT POWER SUPPLY MODULE
D ESCRIPTION
CME’s high-density multi-output, nominal 28V input DC-DC
power supply modules are designed for mission critical applications while providing high reliability power in adverse
environments especially for military, telecommunications or
industrial requirements.
This family of power modules provides quality power with a
variety of single or multiple output configurations, in a light
weight modular package. These low voltage modules meet
the demand for excellent power stability during extreme
EMI/EMC conditions and severe environmental conditions.
Low Voltage, Low Profile,
Multi-Output (3 Outputs Standard)
Power Supply Module (Up to 125W)
The DC-DC Converter provides 22.0 to 30.0 Vdc Input, 28Vdc
nominal, and has input adjustable current limit. The module
provides a differential signal indicating the state of the output voltage.
Utilizing the latest in power switching technology these high
density light weight power modules can be used in a number
of stackable and configurable power bus applications.
A PPLICATIONS
