EAR-CH Charger Discharger

The Charger-Discharger EAR-CH serves to test, charge, discharge and commissioning of aircraft batteries. The device provides over 20 pre-installed programs of operation for all types of batteries. Also, creating and saving of user-defined settings is available. With a printing protocol and the ability to connect to a computer you are able to store the maintenance history of each battery.

Besides prescribed charger/discharger programs there is a possibility to install charger/discharger parameters manually using digital display. Voltage and temperature measurement are performed by every element with special «Probe» testers. Without connection to the battery EAR-CH can be used as a DC power source. Users can save programs that they compiled personally; additionally 20 programs are already set in the Unit. If electrical power is lost to the system, the EAR-CH has a memorizing function so the unit`s last state will be restored.
