August 12, 2011 – Wago Corp. claims its new Feedthrough Current Sensors continuously measures DC currents to optimize photovoltaic (PV) energy production. “Via serial connection, the 789-620 (0–80A DC) and 789-621 (0–140A DC) sensors transmit data with an accuracy of 0.5% (full scale value),” and can be used to quickly identify defective or damaged PV modules, bolstering performance and reliability, it says. According to Wago, the sensors are equipped with dual RJ-45 interfaces and transmit data via RS-485 serial communication lines up to 4000 feet. The sensors are said to operate in temperatures of -20°C to +70°C.
