AMREL Introduces Military Grade Fixed Power Supply
American Reliance Inc. (AMREL) introduced its new ePower MFP300 military grade fixed power supply. AMREL states that it developed the MFP300 to address a ground based military application requiring an ultra-compact, powerful, clean and MIL-STD rugged 28Vdc/300W dc power supply.
AMREL states that it engineered a blueprint to overcome three major technical limitations of existing solutions; convection-cooled with power dissipating components in an ultra-compact MIL-STD Rugged package, 440Hz PFC input while meeting MIL-STD 461E EMI/RFI standards and a precision-regulated dc output with less than 2mVrms of noise. Having exceeded the design targets, AMREL states that it is now ready to launch what it describes as an industry first – the silent, sealed and rugged C.O.T.S. MFP300.
AMREL’s military-grade MFP300 is said to effectively power dc devices in the harshest outdoor conditions. The devices enclose 300W in a 12 x 7.6 x 3.5" package – 300W enclosed in 320 in³ of anodized hardware weighing just over 8lbs. The conformal coated internal dc power engine is enclosed in a rain, dust, sleet and sand resistant package, sealed watertight and then extensively tested under temperature cycles from -40 - 70°C.
The MFP300 utilizes what is described as an innovative interleaved PFC design that takes auto-ranging 85~250Vac and 5~440Hz ac input and also can run off of 95~250Vdc. The dc-operable input and 440Hz operating frequency are unique features exclusive to AMREL’s MFP series.
For applications with a 400Hz ac generator or a dc power source, simply plugging in AMREL’s MFP300 can power devices on your aerial or ground vehicle with an adjustable dc voltage from 24~28Vdc @ 300W. The MFP300 generates a precision-regulated dc output with a ripple of 2mVrms, providing a source for noise-sensitive devices. The device is designed according to MIL-STD 810F Shock and Vibration standards as well as MIL-STD 461E EMI/RFI standards.
