Features
Consistent, high-precision current testing across a wide temperature range Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6841 and CT6843 are DC to 1 MHz/20 A and DC to 500 kHz/200 A sensors, ideal for capturing signals during the efficiency testing of batteries, inverters and power conditioners. • CT6841 (20 A AC/DC) • CT6843 (200 A AC/DC) These products cannot be used alone. The optional 9555-10 is required in order to supply power and connect the clamp to a Memory HiCorder or other instrument. Products can be directly connected the Power Meter 3193-10, and 3390 • Ideal for use in environmental testing, broad temperature range -40˚c to 85˚c• High precision with a clamp-type design, ±0.3% amplitude accuracy, ±0.1 degree phase accuracy• Wide-bandwidth DC to 1 MHz (CT6841), DC to 500 kHz (CT6843)• Single-handed operation, and robust locking mechanism• Reduced effect of magnetic, position of the conductor, and noise from nearby wires• For EV/HEV battery charge and discharge efficiency measurement, and Inverter and power conditioner conversion efficiency evaluation
