Hioki CT6877-01 - AC/DC Current Sensor (2000A DC-1MHz 10m Cable)

• High accuracy measurement realized through flat frequency characteristics and CMRR performance
• More enhanced environmental resistance performance than ever before lets you measure in -40 to 85°C situations
• Improved basic accuracy of ± 0.04% and phase accuracy of ± 0.1°
• Superior frequency characteristics of DC to 1 MHz (amplitude)
• Meet a wide range of applications from measuring battery charge/discharge to the secondary side of inverters in photovoltaic power generation and fuel cell evaluation, etc.

Hioki pull-through AC/DC current sensors are best-in-class devices for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6877 is a DC to 1 MHz/2000A sensor, ideal for capturing current signals from switching power supplies, inverters, power conditioners, etc.

Through Current Sensor for 2000A

Most large currents are divided into two to four wires. In the past, it was necessary to measure wires individually using multiple current sensors due to the devices’ insufficient aperture size and current ratings. The optional Sensor Unit CT9557 provided functionality for adding together the sensors’ measured values in such setups and outputting the result as a single signal. Thanks to its large, 80 mm aperture, the CT6877 can accommodate four wires with an outer diameter of 31 mm (equivalent to a cross-sectional area of 250 mm2). In this way, a single sensor can be used to collectively measure wires carrying up to 2000 A.

Unparalleled Technology Driving The Evolution of Current Measurement

Current sensor performance is maximized with the “Zero Flux (Fluxgate Detection)” measurement method. High frequency current is detected with windings (CT method), and direct to low frequency current is detected with fluxgates. Use of a newly developed opposed split coil* for the winding (CT) makes possible a broad measurement band, while strengthened shielding boosts anti-noise performance. *Opposed Split Coil: Coil in which divided windings are arranged opposite each other on a magnetic core to broaden the range of current detection

Broad Frequency Band

The CT6877 has a frequency band of DC to 1 MHz, placing it among the best-performing pass-through sensors rated for 2000 A and making it ideal for measuring currents being switched at high frequencies by SiC/GaN elements.

Guaranteed Accuracy when used in cobination with a power meter

Since the company develops both current sensors and power meters, Hioki is able to guarantee the combined accuracy of the products when used together for greater customer peace of mind. Used in conjunction with a high-precision power meter such as Hioki’s Power Analyzer PW6001, the CT6877 can measure currents with a high degree of accuracy. ● Example of the CT6877 being used with the Power Analyzer PW6001 From DC to 2 MHz, industry’s proven solution for high-accuracy power analysis. The PW6001 features a phase shift function for current sensors to lock in accurate measurement of high-frequency power. 5 MS/s sampling at 18-bit resolution ensures true power analysis of PWM waveforms and results that are free of aliasing error.
