CT2000A AC/DC Current Sensor
Through-hole AC/DC current sensor for the largest currents on a WT series power analyzer or PX8000. It measures 0 to 2000 A DC and 2000 A rms (3000 A peak) AC, with basic accuracy of ±(0.05% of reading + 30 µA) and bandwidth from DC to 40 kHz.
When several CT2000A sensors are powered from the WT1800E or PX8000 /PD2 option, keep the total supply current within 6 A (WT1800E, channels 1 to 6) or 4 A (PX8000, channels 1 to 4).
