Campbell PS200, CH200 Specifications

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

COMPONENT

PS200 and CH200

Smart Power Supply and Charge Controller

Optimized Power

Performance

Manages voltage and

amperage to protect battery

charging and use. The PS200 includes a 12 Vdc valve-regulated lead­acid (VRLA) battery, while the CH200 is for use with a separate larger
battery such as our BP12, BP24, or a user-supplied battery.

Benets 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

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.

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)

VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries ≤50°C.

b

Battery voltages below 8.7 V may result in <3.0 A current limit because of fold-back current limit.

d

Impulse type changes in current may have an average current error of ±(10% of reading + 2 mA).

e

1.0 V negative oset is worst-case due to reversal protection diode on input. Typical diode drop is 0.35 V.
