Hall Effect sensors is equipped with input reference pin
Key characteristic of the DSR5 series is that the sensor includes an external pin that allows access to the internal reference (2.5 V). The pin can be used as an output or input signal to be used by microcontrollers providing better offset control at zero current.
The series has been designed for nominal currents of 6, 15, 25 and 50 Amps. The multi-pin configuration allows different range of nominal currents by connecting 1, 2 or 3 pins in the primary winding.
The output signal is centered at 2.5 V with an output voltage of ±0.625 V at nominal input currents, but the design allows detecting currents up to three times nominal current.
The sensor also provides a linearity <0.1% with a ±0.7% accuracy levels. Bandwidth is up to 150 kHz with a response time below 0.5 us. Offset drift versus temperature is as low as 0.3% mV/ºC and consumption of the circuit is only 20 mA at no current condition.
The current sensor is specially designed to meet the highest safety requirements. It is fully isolated with plastic housing, meeting isolation values higher than 3000 Vac.
The device is fully compliant to the following industrial standards:
- Isolated plastic case recognized according to UL94-V0
- EN 60947-1:2004
- EN 60950-1:2001
- EN 50178:1998
