MIL-CDRSeries^TM

AJ’s Power Source Inc. (AJPS) Cage Code (0P327) is pleased to announce the release of our new MIL-CDRSeries. This new series is a Ruggedized Military compliant power conditioning system built for deployment and operations equipment. These units are available to all military, homeland security and government contractors. Built for a Very Low EMI signature and very High Reliability this power system will keep your product up and running for many years to come.

The MIL-CDRSeries is a 1U power conditioning system that provides up to 800 Watts at 115 VAC 60Hz. This is a fully isolated in line double conversion system with input surge protection. This system has many unique features such as over voltage, over current, over temperature and short circuit protection. Stainless steel side rails allow for multiple rack depths and the system has field replaceable filters and fans. This system also contains a 24VDC emergency input that will allow for the system to be powered from any 24VDC source if or when AC inputs are not available.

EMI/EMC

The conditioner system has been designed to comply with all of the radiated emissions, susceptibility and conductive emissions requirement of the applicable sections of MIL-STD-461E. These techniques have been used successfully by AJPS to comply with these standards many times in the past. The following is a list of methods used for controlling emissions:

1. Metal Chassis with gaskets on all non sealed interfaces
2. EMI Filters on all input and output power lines
3. Internal circuitry shielded and isolated
4. Ground Planes used for noise isolation
5. Connectors area isolation from Conversion Area
6. External line filter and shielded cables required

AIR FILTERS

Air filters should be placed on a regular maintenance schedule. Suggested inspection should be once a month for any outdoor or high dust environment. The filters can be washed with warm water and soap or blown out in the reverse direction with an air compressor. Regardless of cleaning and inspection processes the filters should be replaced one a year minimum.

FAN MODULES

The systems rear fans have been design for field replacement and only need replacement in the event of a failure. These fans should be inspected at the same time that the filters are cleaned or changed. If one of the fans is operating slowly, stuttering, or stopped the assembly must be replaced.

OUTPUT POWER CABLES

Output power cables are available upon request. The output power cable will need to be shielded from source to termination if system is required to meet MIL-STD-461E.
