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 3-4.

3.1.2 AC/DC Power
Double check the input voltages coming in to the charger/regulator with a volt
meter.
AC Input Voltage: 14 to 24 VAC RMS
DC Input Voltage: 15 to 40 VDC
Exceeding the voltages listed above will damage the
power supply.
Disconnect the primary side of the AC/DC power before connecting wires to the
PS150.
