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.

Ordering Information Continued
aVRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries ≤50°C.
bBattery voltages below 8.7 V may result in <3.0 A current limit because of fold-back current limit.
cTwo-step temperature compensated constant-voltage charging for valve-regulated lead-acid batteries. Cycle and oat charging voltage parameters are
programmable with the default values listed.
dImpulse type changes in current may have an average current error of ±(10% of reading + 2 mA).
e1.0 V negative oset is worst-case due to reversal protection diode on input. Typical diode drop is 0.35 V.
f2.0 V negative oset is worst-case due to two series diodes in AC full-bridge. Typical diode drops are 0.35 V each for 0.7 V total.
