1
Battery voltages below 8.7 V may result in <3.0 A current limit because of fold-back current limit.
2
VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries ≤50°C.
3
Two-step temperature compensated constant- voltage charging for valve-regulated lead-acid batteries. Cycle and fl oat 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).
5.
1.0 V negative off set is worst-case due to reversal protection diode on input. Typical diode drop is 0.35 V.
6.
2.0 V negative off 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.

CH200 and PS200
Smart Charging Regulator and Power Supply
A CR1000 is connected to the PS200 ‘s SDI-12 terminal allowing
the CR1000 to receive the PS200’s charging, load, battery volt-
age, and current information.
