Product catalog summary
Specification Overview:
The document outlines the specifications for the VACUUMSCHMELZE Differential Current Sensor, item number T60404-N4641-X920, compliant with IEC62752-1:2016 standards. It is primarily designed for mobile applications, particularly in IC-CPD systems.

Key Features:
  • Fluxgate current sensor with toroidal core for PCB mounting.
  • High accuracy and AEC-Q qualified components.
  • Compact design with switching open-collector outputs.

Electrical Specifications:
  • Primary rated current: 32-40 A.
  • Rated residual operating currents: 6 mA DC and 30 mA rms.
  • Response time and frequency range: DC to 2 kHz.
  • Operating temperature: -40°C to 85°C.
  • Supply voltage: 4.8 to 5.2 V.

Mechanical and Connection Details:
  • General tolerances follow DIN ISO 2768-c.
  • Pin descriptions include ERROR-OUT, TEST-IN, X6-OUT, X30-OUT, GND, VCC, PWM-OUT, and N.C.
  • Data-Matrix-Code includes VAC, 4641-X920, Factory, and Date Code.

Performance and Testing:
  • Final tests ensure supply voltage, current, and output voltages are within specified ranges.
  • Product tests include rapid temperature changes, damp heat, and partial discharge voltage tests.
  • Requalification tests are conducted annually, including impulse and test voltage checks.

Application and Usage:
  • The sensor is sensitive to both AC and DC currents, used for fault current detection.
  • In case of fault currents, specific pins change state to signal errors.
  • Patents related to the sensor include EP2571128, US9397494, CN103001175, and EP2813856.

Additional Information:
  • Temperature of primary conductors should not exceed 105°C.
  • Vcc during Test-IN function must be within the rated range.
  • Figures and diagrams illustrate power-up timing and response values over frequency.

Customer: Standard type Requalification Tests: (replicated every year, Precondition acc. to M3238) Temperature of the primary conductor should not exceed 105°C. Vcc during Test-IN function test must be in rated range. If the trip-level Ian1/Ian2 is accomplished the corresponding output X6-OUT/X30-OUT will change its state from low-level (GND) to high impedance. Depending on the existence of the differential current Ia, the outputs X6-OUT/X30-OUT will remain in their states until Ia is below the recovery threshold Iarm/Iari2.
