Power Supplies
Designed specifically for the SDI-12 bus, the T110 power supply can be used in applications where electricity is not available. The T110 power supply includes a robust, maintenance free lead-acid battery and a controller to assist the battery charge. In addition, the power supply is itself an SDI-12 node on the bus, delivering battery status information to the SDI-12 data logger.
The power to charge the battery is obtained typically from a solar panel, but any current limited source can be used.
