1. SYSTEM OVERVIEW
1.1 SYSTEM OVERVIEW
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 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 trimpots allow user voltage changes if
required. In CC (Constant Current) mode, there is no voltage adjustment.
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.
1.2 DISPLAYS AND CONTROLS
The Alpha C-25 has been designed to have very simple and easy to
understand controls and displays
(see figure 1-1 and 1-2).
There is a trimpot for the 12 Volt, and a trimpot for the 24 Volt constant
potential setting on the front panel for adjustment of the end of charge
voltage.
