PS150/CH150 12 V Charging Regulators

3.1 Connecting Power
Although the power supply and battery are low voltage,
they do have the ability to supply a high current and
could potentially heat up a metal ring, watch band, or
bracelet enough to burn skin or melt metal when
shorted. Remove rings, watches, or bracelets before
hooking up power and connecting a battery.
Unlike earlier Campbell Scientific power supplies, the CH/PS150 can have
both solar and AC power hooked up simultaneously.
Flip the power supply switch to
Off
before hooking up power to the power
supply.
The switch on the CH/PS150 only controls power going to the
12V
and
G
terminal blocks. The battery is continuously charged
regardless of the switch setting as long as a charging voltage is
present.
3.1.1 Solar Panel
To prevent sparking while wiring up the solar panel,
either lay the solar panel face down on its packing box
or cover it with something fairly opaque to block the
sunlight while wiring up the panel.
Connect the black (negative) lead from the solar panel to the terminal block
marked
G
that is directly adjacent to the
SOLAR
terminal block. Connect the
red (positive) lead from an unregulated solar panel to the terminal block
marked
SOLAR
. See FIGURE
