Rodale wins Army contract to provide power electronics units for EPLRS network radio communications

Military power electronics designers at Rodale Electronics Inc. in Hauppauge, N.Y., will provide the U.S. Army with Enhanced Position Location Reporting System (EPLRS) Dual Power Adapter (EDPA) units under terms of a $23.2 million contract award from the Army Contracting Command at Aberdeen Proving Ground, Md.

The Rodale EDPA is the physical interface between the EPLRS trans- mitter unit and the EPLRS AC or DC power source. EPLRS is a secure, jam-resistant, computer-controlled military communications network that distributes near-real-time tactical information, as well as provides position location and reporting. EPLRS uses Time Division Multiple Access (TDMA) technology and a frequency hopping, spread spectrum waveform in the UHF band.

The Rodale EDPA conditions input power to EPLRS and enables the EPLRS receiver/transmitter unit to operate from an external power source of 20 to 32 volts DC or 108 to 32 volts AC single phase at 47 to 63 Hz, or 198 to 242 volts AC single phase at 47 to 63 Hz European.

The EDPA converts, rectifies, regulates, and conditions the external AC/DC power source that supplies necessary voltages and current when connected to the EPLRS receiver/transmitter. The unit meets MIL-STD-810C, MIL-STD-428, MIL-STD-1275, and MIL-S 901C. It is 10.2 inches long, 3.52 inches high, and 4.96 inches wide, and weighs 10 pounds. The EDPA operates from -46 to 71 degrees Celsius.

The Army is awarding Rodale a firm-fixed-price indefinite-delivery/indefinite-quantity contract. Rodale will do the work in Hauppauge, N.Y., and should be finished in 2017.
