Smart Powered Hub and Smart Hub
Smart Powered Hub and Smart Hub
The Smart Hub is a passive 6 to 1 hub for 2-wire RS-485 signals allowing connection of several extra instruments to the RaZON+ (end of 2018).
The hub also allows to concentrate several Smart Kipp & Zonen pyranometers and pyrheliometers to one cable to a data logger like the LOGBOX SE or host.
All this in a weatherproof solution without the need for extra enclosures.
The Smart Powered Hub adds an oversized power supply capable of delivering 24 V and 2.2 A max. Enough to power a DustIQ, a RaZON+, a SOLYS2, a LOGBOX SE and many low power instruments.
No separate AC to DC power adapter is required, the PMU485 contains a small rechargeable Lithium-ion battery and a DC-DC converter to provide 12 V to the device. The built-in 2-wire RS-485 to USB 2.0 converter controls the data connection and a 1.5 m USB cable is supplied. All Kipp & Zonen Smart radiometers are supported; SMP, SHP, SGR, SUV, PR1, PH1, RT1 and also the DustIQ Soiling Monitoring System.
There is no power switch on the PMU485, connecting it to an active USB port starts the converter. Together with our SmartExplorer software it can be used to test the device, configure communication settings and log data.
PMU485 is intended to be used as an installation or service tool to set up and test a device and its communication parameters. It can power and communicate with up to 10 radiometers connected in parallel, and SmartExplorer can display and log data from all of them. However, it can only power one DustIQ.
The Smart Hubs are easy to amount on a flat surface.The optional pole mount allows for easy mounting on a small ⌀ 30 to 90 mm pole or a large ⌀ 50 to 370mm pole like the SOLYS2 extension tube.
