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)

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.
