Figure 5-1. PS150/CH150 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 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 SOLAR – G input terminals are intended for
connection to solar panels, or other high-current DC sources. Polarity definitely
matters on the DC only SOLAR – G input terminals, with positive connected to
SOLAR and the return or negative connected to G, with reversal protection
included. The SOLAR – G input terminals have an input current limit of
approximately 3.6 amps, making the PS150/CH150 well suited for
70 watt or
smaller solar panels. The PS150/CH150 can be simultaneously powered from
both the CHARGE – CHARGE and SOLAR – G input terminals, as the internal
diodes will route power from the source with the highest input voltage. This
allows for an AC mains powered application with a solar panel for back-up. If the
reverse is needed – solar power as the primary supply and AC as the secondary
supply – then a solar panel should be used with a 24 VDC output and an AC, or
AC to DC, source with a voltage output less than the solar panel voltage.
