Edition
Unit has interchangeable blades. Unit ships with UK/CEEE plug.
The recommended chargers have dc voltage output which can be
used on either the CHARGE/CHARGE or SOLAR/G terminal
blocks.
Maximum input charging current on the
CHARGE/CHARGE terminal blocks is limited to 1.1 Adc.
Maximum input charging current on the SOLAR/G terminal blocks
is limited to 3.6 Adc.
CHARGE/CHARGE terminal blocks have no polarity. Power wires from the
charging source can be connected in any fashion. The PS150/CH150 will only
float charge a battery with power connected to the CHARGE/CHARGE terminal
blocks which is fine when using an AC/DC charging source.
SOLAR/G terminal blocks do have a polarity that must be followed when wiring
up either of the AC/DC devices. Positive wire goes to the terminal block marked
SOLAR. Negative wire goes to the terminal block marked G. Higher power
throughput makes this an attractive option. It will float charge a battery but it will
also try to quick charge as well depending on the needs of the battery.
5. Operational Overview
A simplified schematic of the PS/CH150 charging regulator is illustrated in Figure
5-1. 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, Ltd., for the CH150. See
Section 4.2 , Battery Packs , for
rechargeable batteries offered for the CH150 by Campbell Scientific.
