DS400UB-10V

Product catalog summary

Features: The DS400UB-10V current transducer features a maximum linearity error of 27 ppm, a 10V BNC output connection, and utilizes fluxgate, closed-loop compensated technology for high accuracy and stability. It includes a DSUB 9 pin connection, a green diode for operation indication, and an aluminum body for EMI shielding and temperature range extension. It supports non-intrusive, isolated DC and AC current measurement up to 440A.

Applications: This device is suitable for use in particle accelerators, MRI gradient amplifiers, stable power supplies, precision drives, battery testing, power measurement, and current calibration.

Specifications: The nominal primary AC current is 283 Arms, and the DC current ranges from -400 to 400 A. The measuring range extends to ±440 A. The primary/secondary ratio is 25.000 V/kA. The device operates within a temperature range of -40°C to 85°C and requires a power supply voltage of ±14.25 to ±15.75 V.

Electrical Specifications: At 23°C and a supply voltage of ±15V, the device has a bandwidth of 300 kHz and a response time of 1 µs. The amplitude error varies with frequency, and the phase shift is minimal across the specified frequency range.

Isolation Specifications: The device has a clearance of 9 mm and a creepage distance of 10 mm. It can withstand an impulse voltage of 10.4 kV and has a rated rms isolation voltage of 300 V for reinforced isolation.

Advanced Sensor Protection Circuits (ASPC): These circuits protect the transducer from fault conditions, allowing DC and AC primary current up to 100% of nominal value without damage. The sensor core may become magnetized, causing a minor output offset change.

Accessories: Available accessories include a 4-channel power supply unit and various lengths of transducer cables.

Mounting Instructions: The device can be mounted using base plate or back side panel methods, with specific screw sizes and torque requirements.
