1.8.1
External Power Supply / Solar System
The CDS541 Cumulus Pulse logger can be powered entirely from an external 12V (8
source. Using a solar power source and also populating the logger with alkaline batteries means that the logger can be put
into dual mode. In this mode, while there is solar power available, the logger will remain online with the server. Should the
solar power fail, the logger will automatically switch to 'battery' mode until the solar power source is restored. This is id
for remote applications where there is no mains power available and streaming data is required.
1.8.2
Using the Digital Output
The output on the CDS541 Logger can be used to switch a DC device of up to 500mA at a maximum of 50V. This output is an
open drain output that will switch to ground.
