Application
Used to control and power a DC motor from a solar panel. The unit
prevents stalling of the motor under less than full sun condition. The
power of the sun is transformed to the motor running conditions so as
the sun goes down the motor slows down instead of stalling. Conversely,
or as the sun comes up the motor starts running much earlier instead of
staying stalled for hours when it could be running. This translates
into more running time of the motor where it spends a lot of time
working instead of stalled doing no work. Voltage Limited Output

** Special units have a suffix of M XX after the part number. The
maximum output voltage
of the pump driver is XX. For example PPT 12/24 - 15 M6 will power a 6
V motor from a
nominal 12 V solar panel. Note that the motor current increase by the
ratio
of approx. 15/6. Thus a 1 amp 12V nominal solar panel will power the
motor at 2.5 Amps.
