Overview

The PS200 is a 12-Vdc battery with a charge controller. The controller manages amperage and voltage for safe, optimized battery charging from a solar-panel or AC power source. It also measures various input, output, and status parameters to allow close monitoring of the battery during charging and use. The PS200 includes a 12-Vdc lead-acid battery, while the CH200 is for use with a user-supplied battery.

Note: If you do not need or desire the 6182 7 Ah Sealed Rechargeable Battery that is shipped with the PS200, consider ordering the 22238 instead.

Detailed Description

The PS200 power supply consists of a rechargeable, 7 A h, valve-regulated lead-acid (VRLA) battery and a charging regulator. This microcontroller-based smart charger has 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. The PS200 also incorporates a maximum power point tracking algorithm for solar inputs that maximize available solar charging resources. RS-232 and SDI-12 terminals allow the PS200 to convey charging parameters to a datalogger.

The PS200 has 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 also has battery-reversal protection, and includes ESD and surge protection on all of its inputs and outputs.

Measurements
-NOTE- At -40° to +60°C
Average Battery Voltage ±(1% of reading + 15 mV)
Average Battery/Load Current Regulator Input Voltage ±(2% of reading + 2 mA)

Impulse type changes in current may have an average current error of ±(10% of reading + 2 mA).
Solar ±(1% of reading - 0.25 V) / -(1% of reading + 1 V)

1.0 V negative offset is worst-case due to reversal protection diode on input; typical diode drop is 0.35 V.
Continuous ±(1% of reading - 0.5 V) / -(1% of reading + 2 V)

2.0 V negative offset is worst-case due to two series diodes in AC full-bridge. Typical diode drops are 0.35 each for 0.7 V total.
Charger Temperature ± 2°C
