Dual output charger for all types and ratings of Nickel Cadmium, sealed or vented Lead Acid aircraft batteries

The Alpha C-25 Charger is a self-contained unit for charging of rechargeable batteries. It has been designed to charge one or two batteries of the same voltage rating simultaneously, to a combined maximum of 25 amperes. At 40 lbs. and 15 by 5 ¾ inches (381 by 146mm) the C-25 takes minimal space and can easily be moved to add flexibility to the work environment. The charger height and depth are the same as the Power Products’ discharge tester, Beta D-50, with the same general appearance. Therefore, two adjacent units comprise a charger/discharger, which can service from one to three batteries simultaneously, lead-acid or nickel-cadmium.

The Alpha C-25 allows charging at both constant potential and constant current to give flexibility in the selection of charge method. The C-25 charger has an adjustable charge current from 0 to 25 amperes in the CP (Constant Potential) mode. End of voltage settings should be 14.3 for 12 Volt and 28.5 for 24 Volt batteries. Panel trim pots allow user voltage changes if required. In CC (Constant Current) mode, there is no voltage adjustment. The maximum voltage is approximately 37 volts. Two digital panel meters allow viewing of charge current and voltage. They can be switched to allow viewing of either of the two batteries being charged. A digital electronic timer displays elapsed time and can be set to a fixed duration charge period.

The flexibility of settings of the Alpha C-25 makes it usable for a wide variety of batteries and voltages. The unit efficiently charges Lead Acid batteries of 12 or 24 volts, as well as Nickel Cadmium batteries of a single cell to 24 volts. 

This unit can be used in conjunction with the Power Products / Lamar Beta D-50 battery discharge analyzer
