PS100 and CH100 Power Supply and Charging Regulators, A100 Null Modem Adapter, and A105 Additional 12 V Terminals Adapter 1. General Description The PS100 is a 12-volt power supply that includes a charging regulator and a 7 amp hour battery. The CH100 is a charging regulator that is used with a Campbell Scientific battery pack such as the BP12 or BP24 or with a usersupplied battery. Charging power is typically supplied by an AC transformer or an unregulated solar panel.

Permanent damage occurs and battery life is shortened if the battery is allowed to discharge below 10.5 volts.
PS100 and CH100 Power Supply and Charging Regulators It is possible to leave two batteries connected. The battery connections are diode isolated (Figure 2); however, if one of the batteries fail, it could draw all the charging current and the other battery will be discharged. CAUTION A battery must be attached for the charger to function correctly as a power supply. The leads from the transformer or solar panel are connected to the CHG terminals.

A105 12V Terminal Expansion Adapter The A105 adapter adds four 12-V terminals and four ground terminals to a CH100 or PS100 (see Figure 4). The extra terminals make it easier to wire multiple continuously powered 12-Vdc devices to the power supply. FIGURE 4.
