PMU485

The PMU485 is a power source and data connection between a smart Kipp & Zonen sensor and a PC. 

No AC power / adapter is required, the PMU485 contains a small lithium battery and a DC-DC converter to power the sensor. The built in RS485 to USB converter controls the data connection and comes with a USB cable. All Kipp & Zonen SXX sensors are supported, as well as the RT1, PR1, PH1 and DustIQ. There is no power switch on the PMU485, connecting it to an active USB port starts the device. Together with the SmartExplorer it can be used to test, read-out, set-up and log the connected sensor(s). 

The PMU485 can be an installation or service tool to set-up and test the sensor and its communication parameters.

When in use with only pyranometers it can support up to 10 devices, also the SmartExplorer software can display these connected devices all at once.
