Supplement
This supplement includes additional information specific to the 24 Volt version of the Smart Charge Manager (SCM-24).

Ample Power Smart Charger System II 24V
The Ample Power Smart Charger System II 24V consists of one SCM-24, one SCM-24 Balancer Module, two to eight Power Supply Chargers (PSC), and one isolator for each PSC. Other miscellaneous options may also be added such as: a shunt for current limiting, a remote alarm, remote switches, or a parallel solenoid.


Mounting the SCM Balancer Module
The SCM Balancer Module is protected against ambient humidity, but must be mounted in a dry location free of moisture, dust and other environmental insults. It will operate in temperatures to 60$^\circ $C (140$^\circ $F).

24V Wiring Diagram
For proper operation of the SCM-24, wire it as shown in Figure 1. Do not wire it in any other way, such as combining ground wires or battery positive wires. For safety purposes, always use fuses where shown.


Signal Names and Functions
As shown in Figure 1, there is one 7-pin terminal blocks for the SCM Balancer Module


Stacking and Packing Power Supply Chargers
Figure 2 shows how to stack and pack power supply chargers modules in series-parallel for increased amperage output capability in 24V systems. Note that the modules are first connected in parallel. Each power supply/charger module on the lower 12V side connects to one of the control lines on the SCM-24. Each power supply/charger module on the upper 12V side connects to one of the control lines on the SCM-24 Balancer. The lower 12V and upper 12V banks are then connected in series for 24V.
