Feedthrough Current Sensors
Wago Corporation’s new Feedthrough Current Sensors continuously measure DC currents to optimize photovoltaic energy production. Using a serial connection, the 789-620 (0-80A DC) and 789-621 (0-140A DC) sensors transmit data with an accuracy of 0.5 percent (full scale value). This can be used to quickly identify defective or damaged PV modules to bolster performance and reliability, according to the company.
The sensors are equipped with dual RJ-45 interfaces and transmit data via RS-485 serial communication lines of up to 4,000 feet.
