5. Operational Overview
A simplified schematic of the CH/PS150 charging regulator is illustrated in

. A 12-V 7Amp-hr rechargeable battery is included with the
PS150, whereas the user provides the rechargeable battery, such as the BP12 or
BP24 offered by Campbell Scientific, Inc., for the CH150. See Section

Charging power for the PS150/CH150 is typically supplied by an unregulated
solar panel, AC/AC transformer, or AC/DC converter. The
CHARGE –
CHARGE
terminals are connected to a diode bridge, accommodating either
AC or DC voltages from a charge source. Because of the diode bridge, polarity
does not matter when connecting sources to the
CHARGE – CHARGE
input
terminals. In order to protect AC/AC or AC/DC sources when charging
discharged batteries, the
CHARGE – CHARGE
input terminals offer an
approximately 1.1 amps DC (1.2 A RMS) current limit. The
