The CA-1550 CML Charger/Analyzer is a portable or bench mounted self-contained unit
for charging and discharge capacity testing of 12 and 24 volt aircraft or ground support
batteries. The unit’s intuitive design facilitates its ease of use and does not require
programming or use of a computer. Digital read-outs of volts, amperes and time are
clearly displayed. The CA-1550-MIL has been designed to accurately charge, test and
ensure the emergency capacity of sealed lead-acid (SLAB) or nickel-cadmium (NiCad)
batteries. However, the CA-1550-MIL is capable of charging and discharging batteries
other than 12 and 24 volt SLAB and NiCad batteries by altering the time, current and
voltage settings as required.
The unit comes in a convenient protective carrying case. The case is NOT intended as a
shipping case. The flexibility of the charge and discharge functions of the CA-1550-MIL
make it usable for a wide variety of batteries. The unit accurately charges and tests
batteries from a single cell to 22 cells.
The charge section of the CA-1550-MIL allows charging at either constant potential or
constant current to give maximum flexibility in selection of the charge method. The
charger has an adjustable charge current from 0 to 25 amperes, and an automatic time to
read and/or terminate charge and discharge time.
The discharge section of the CA-1550-MIL enables battery capacity testing with a
constant current of 0-50 amperes. The unit automatically measures the battery voltage
and passes or fails the battery depending on the battery’s ability to maintain the specified
minimum voltage for the pre-settable time, (usually one hour). All meters “freeze” their
readings at the end of test and the operator thereby knows the precise ampere hour
capacity of the battery.
The CA-1550-MIL includes an integrated battery temperature monitoring plate. This
accessory allows the user to set up a test with limited monitoring. The plate is designed
to shut down the charge or discharge portion of the test if the battery exceeds 50°C.
