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 for the CH150. See

, for rechargeable batteries offered for the
CH150 by Campbell Scientific.
FIGURE 5-1. CH/PS150 schematic
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 full bridge rectifier, accommodating
either AC or DC voltages from a charge source. Because of the rectifier,
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
SOLAR – G
input terminals are intended for connection to solar panels, or
