Do not power up the A22K until all connections are completed.
The module operates from any 120/240 Vac source using the supplied AC/DC power supply and provides fully
monitored power solutions using:
• Smart Battery Deep discharge prevention with automatic electronic cut-o.
• Programmable & Adaptive battery charging algorithm (250mA (default), 500mA, or 1A).
• Intelligent battery monitoring & charging algorithms allowing optimum performance using standard
lead acid or gel cell type batteries.
• Real Time Monitoring algorithm for ‘Battery Low/Disconnect/Reversal’ and ‘Insucient Main Power’.
AC Source
The AC to DC power supply is pre-installed in the A22K box but needs to be connected to the PCB. Simply plug
the two pin terminal to the input power supply.
