MBC Series Current Transducer
The MBC4000I is a closed-loop fluxgate DC current transducer for galvanically isolated measurement of 4000 A continuous and up to 6000 A, with a linearity error below 50 ppm and a maximum total error of 200 ppm. The 5000:1 turns ratio keeps the secondary current at 800 mA at nominal current, and the fluxgate principle gives low offset and drift in a compact housing with a 120 mm aperture.Who Is the MBC Series For?
Engineers who need galvanically isolated high-current measurement in solar and wind inverters, battery energy storage systems (state of charge and state of health), variable frequency drives, solid state transformers, UPS systems, energy metering, and substation monitoring and power quality.Available Models & Accessories
The MBC Series comprises one model, MBC4000I, with current output. It runs on a supply of ±14.5 to ±25.2 V; at ±14.5 V the nominal current is derated to 2200 A.200 ppm total error at 4000 A.
Linearity error stays within ±50 ppm of reading, ratio error within ±100 ppm, and offset including the earth field within ±100 ppm of nominal DC current. The offset temperature coefficient is at most 1 ppm/K. For DC to 10 Hz the total accuracy without offset is 0.01 % of reading plus 0.00002 % of full scale.
0.2 ppm rms noise up to 1 kHz.
Noise is specified as 0.2 ppm rms of nominal DC current from DC to 1 kHz, 0.3 ppm rms up to 10 kHz and 2.8 ppm rms up to 100 kHz, with peak-to-peak values of 0.8 ppm below 100 Hz and 18 ppm below 100 kHz. The fluxgate excitation frequency is 46.88 kHz.
Accuracy and phase specified per frequency band.
At 50 to 60 Hz the total accuracy is 0.01 % of reading plus 0.00004 % of full scale, with a phase shift of 0.01°. It relaxes to 0.1 % of reading below 1 kHz, 3 % below 10 kHz and 30 % below 100 kHz. The small-signal bandwidth is 100 kHz and the step response is 6 µs at 10 A/µs.
Isolation, mounting and busbar layout in one datasheet.
Clearance and creepage are 35.4 mm with a CTI above 600 V, and the continuous working voltage reaches 6300 V on basic insulated wire (IEC 61010-1, CAT II). The housing mounts with four M6 holes on the base plate or the back plate, and back plate mounting is recommended where vibration is present. A minimum of 1 mm² of primary busbar per ampere is recommended, and the datasheet gives the distance to keep to the return conductor.
Stable Measurement in High-Current Power Electronics
The closed-loop fluxgate principle gives the MBC4000I low offset and very low drift, with a total error of 200 ppm at 4000 A and an offset temperature coefficient of at most 1 ppm/K. That makes it suitable for long-term monitoring and reference measurements in solar and wind inverters, battery energy storage systems, variable frequency drives, UPS systems and energy metering, where small errors at high currents add up.
Straightforward Installation and Integration
The 120 mm aperture takes large busbars, and the housing mounts with four M6 holes on either the base plate or the back plate. The floating current output on a 3-pin connector delivers 800 mA at nominal current, and the transducer runs on a supply of ±14.5 to ±25.2 V. Isolation is rated for a continuous working voltage of 6300 V on basic insulated wire (IEC 61010-1, CAT II).
