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).

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.
