PS200 and CH200
Smart Power Supply and Charge Controller
Overview
The PS200 and CH200 are charge controllers 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 separate larger
battery such as our BP12, BP24, or a user-supplied battery.

Technical Description
The PS200 and CH200 are micro-controller-based smart chargers
with two-step constant voltage charging and temperature compen-
sation that optimize battery charging and increase the battery’s life.
Two input terminals enable simultaneous connection of two charg-
ing 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 termi-
nals 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.
