amperage to protect battery CH200 and PS200 Smart Charging Regulator and Power Supply Benefits and Features Protects against high-amperage and high-voltage damage to power supply Ability to monitor both load and battery current Real-time measurements of charge input voltage, battery voltage, on-board temperature, battery current, and load current Battery reversal protection Two-step constant voltage charging and temperature compensation optimize battery charging and increase the battery’s life Allows simultaneous connection of two charging sources (e.g., solar panel, ac wall charger) Overview The PS200 and CH200 are charge regulators that manage amperage and voltage for safe, optimized battery charging from a solar-panel or ac power source. They also measure various input, output, and status parameters to allow close monitoring of the battery during charging and use. The PS200 includes a 12 Vdc valve-regulated lead-acid (VRLA) battery, while the CH200 is for use with a user-supplied battery (typically the BP12 or BP24). www.campbellsci.eu/ps200_ch200 More info: +44(0) 1509 828 888 Technical Description The PS200 and CH200 are micro-controller-based smart chargers with two-step constant voltage charging and temperature compensation that optimize battery charging and increase the battery’s life. Two input terminals enable simultaneous connection of two charging sources. They also incorporate a maximum power point tracking algorithm for solar inputs that maximize available solar charging resources. RS-232 and SDI-12 terminals allow the PS200 and CH200 to convey charging parameters to a datalogger. The PS200 and CH200 have 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 PS200 and CH200 also have battery-reversal protection, and include ESD and surge protection on all of its inputs and outputs.

Cycle and float charging voltage parameters are programmable with the default values listed. 4 Impulse type changes in current may have an average current error of ±(10% of reading + 2 mA). 51.0V negative off set is worst-case due to reversal protection diode on input. Typical diode drop is 0.35V.
