Main Power Supply
The main power supply (p/n 30889) is a combination 8 amp system power supply
and battery charger. It provides the system with five supplies (a 24Vdc
regulated, 24Vdc unregulated, 12Vdc, 5Vdc and the battery charger). The
standard battery charger is sized to maintain 5 to 60 AH batteries. The battery
charger card has three resistors for programming various battery sizes. R21 &
R17 should be removed when 5 - 20AH batteries are installed. R1 should be
removed when 21 - 40AH batteries are installed. No resistors should be removed
when 41 - 60AH batteries are used.
