Der CH201 ist ein microcontroller-basierter intelligenter Laderegler, ideal für 12 Vdc VRLA Batterien. Der Laderegler nutzt MPPT (maximum power point tracking) Technologie um die optimale Ladespannung und Stromstärke einzustellen, damit die Batterie lange lebt. Er hat zwei Engänge zur Verwendung mit Solarzellen und/oder einer anderen 15 bis 50 Vdc Stromquelle. Damit gibt es eine besondere Sicherheit gegen Fehler beim Laden. Der CH201 kann auch verschiedene Parameter zur Überwachung von Stromverbrauch und Batterie über RS-232 oder SDI-12 ausgeben.
In unseren Systemen wird der CH201 verwendet, um die Batterie zu laden und um Datenlogger und Peripheriegeräte mit Strom zu versorgen. Der 12 V-Ausgang ist reguliert und kann geschaltet werden, mit der Möglichkeit, eine 12 V Batterie mit 10 A zu laden.

The CH201 has two input terminals that enable fail safe charging should one source drop out. It also incorporates an MPPT (maximum power point tracking) algorithm to maximize available solar. The CH201 has a programmable, low-voltage disconnect to help protect the battery. RS-232 and SDI-12 terminals allow the CH201 to be configured and to convey charging parameters to a data logger.
Compared to the CH200, the CH201 offers faster charging with the use of larger solar panels, up to 160 W. (Larger solar panels can be connected; however, when the system is running at full power, not all the current will be used.)
Compared to the SunSaver SS-10-12V, the CH201 offers:

The CH201 is compatible with SDI-12 data loggers for communications. The CH201 could power any data logger with 12 V.
Two CR1000X data logger programs that monitor the CH201. One example program uses RS-232, and the other example program uses SDI-12 communications.

The total that the CH201 can handle is 10 A. However, unless the two inputs have exactly the same voltage, only one source will be used. Therefore, technically, both sources can be 10 A each, assuming that they will not operate at the same voltage and trip the thermal fuse.
The CH201 uses the input with the highest voltage.
