Portable Military Charger for Zinc-Silver Oxide Batteries

摘要

Battery Charger PP-4127A/U was designed to provide battery charger support for the Ground Surveillance Radar Set AN/PPS-5; the AN/PPS-5 is a portable battery operated system. The power source is a 6-volt, 60-Ah zinc-silver oxide battery. The battery charger provides compatibility between the battery and existing forward area engine generator sets. Proper charging of the zinc-silver oxide battery is a highly specific process. To maintain full charge capability and insure maximum cycle life, the battery must be charged with a controlled constant current at the 10-hour rate. When the battery reaches its end of charge voltage of 2.01 to 2.05 volts/cell, it is fully charged; the PP-4127A/U will then discontinue the charging cycle. The PP-4127A/U will charge two batteries simultaneously in a 10-hour period through the use of two separate channels. It is portable, fully militarized and operational with 115/230 V, 50/60- and 400-Hz power sources. Its overall weight is 40.5 pounds and its efficiency is 53%. (Author)
