The CH200 is microcontroller-based smart charge controller that is ideal for an external rechargeable 12 Vdc VRLA battery such as Campbell Scientific's BP12 or BP24. The controller manages amperage and voltage for safe, optimized battery charging from a solar-panel or ac power source. It also measures various input, output, and status parameters to allow close monitoring of the battery.

Descripción detallada

The CH200 has two input terminals that enable simultaneous connection of two charging sources. It also incorporates a maximum power point tracking algorithm for solar inputs that maximize available solar charging resources. RS-232 and SDI-12 terminals allow the CH200 to convey charging parameters to a datalogger.

The CH200 has several safety features intended to protect the charging source, battery, charger, and load devices. Both the SOLAR – G and CHARGE – CHARGE input terminals incorporate hardware current limits and polarity reversal protection.

A fail-safe, self-resettable thermal fuse protects the CHARGE – CHARGE inputs in the event of a catastrophic AC/AC or AC/DC charging source failure. Another self-resettable thermal fuse protects the 12 V output terminals of the charger in the event of an output load fault.

The CH200 also has battery reversal protection, and includes ESD and surge protection on all of its inputs and outputs.

  1. The CH200 or PS200 will pull power only from the source with the highest voltage at that moment. For example, the regulator will take the 20 W input from the 24 Vdc wall transformer rather than from the 18 V 50 W solar panel—even during the day. If the power goes out, the 50 W solar panel will charge during the day with no charging at night.

  2. The CH100 is a float-only charger that is limited to a 20 W solar panel and a maximum load of approximately 1 A.  

    The more advanced (and more expensive) CH200 is a multistage controller that can charge at higher rates and use larger solar panels (90 W) while delivering a maximum of approximately 4 A to the load, depending on the temperature. The CH200 is a smart charger that incorporates MPPT technology (maximum power point tracking) and can be interrogated by the datalogger to check its state, solar panel status, load currents, battery voltage, and net battery current. In this regard, the CH200 acts as a high-tech sensor, as well as a charge regulator.

    The CH100 has a temperature sensor for temperature compensation. The CH200 has a similar onboard temperature sensor, but it is more efficient and does not dissipate as much heat with a similar load. The CH200 also has a feature where an independent battery temperature measurement can be sent to the charger rather than using its onboard temperature sensor.
