DQ640ID-B

Product catalog summary

Overview: The DQ640ID-B is a current transducer designed for applications requiring high accuracy and programming flexibility, such as stable power supplies and MRI gradient amplifiers. It features closed-loop compensated current transduction and zero flux technology for extreme accuracy.

Features:

Closed loop compensated current transducer
Zero flux technology
DSUB 9 pin connection
Green diode for operation indication
Aluminum body for EMI shielding

Applications: Suitable for stable power supplies, MRI gradient amplifiers, and as a reference transducer for calibration purposes.

Specifications:

Linearity error: 3uA
Maximum offset: 10uA
Operating temperature: 0°C to 55°C
Turns ratio: 1:40 to 1:640, step 20
Maximum compensation current: 1A
Maximum measurement resistor: 1Ω
100-turn test winding (100mA max)
Aperture size: 28.1mm

DC Specifications: At 25°C and ±15V supply voltage, the primary current ranges from -640A to 640A, with a secondary current of -1000mA to 1000mA. The supply voltage ranges from ±14.25V to ±15.75V.

Noise and Stability: Noise levels vary from 0.01uA rms at 0-100Hz to 3.0uA rms at 0-100kHz. Offset stability over time is 0.4uA/year.

Programming and Connections: The transducer can be programmed for different output ratios using a programming plug. A detailed table provides the connections required for each ratio.

Isolation and Safety: The transducer complies with IEC 61010-1 standards, offering reinforced isolation with a rated isolation voltage of 300V and an impulse withstand voltage of 10.4kV.

Advanced Sensor Protection Circuits (ASPC): Protects the sensor from fault conditions, allowing primary current application up to 100% of nominal current even when unpowered or with an open secondary circuit.

Package Content: Includes the sensor, a programming plug (default 1:640), a test report, programming sheet, and CE certificate.

Compliance: The product complies with EC Directives 2014/30/EU and 2014/35/EU, and is manufactured in accordance with the RoHS directive 2011/65/EU.
