A series of Hall effect sensors called DSR5 are for a single supply voltage of +5V. The
DSR5 series is a close-loop component in a small package for THT mounting. It’s primary winding is integrated, which lets it measure dc, ac and pulse currents on printed circuit boards.
Key characteristic include an external pin that gives access to the internal reference (2.5V). This pin can be used as an output or input signal for use by microcontrollers for better offset control at zero current.
This series has been designed for nominal currents of 6, 15, 25 and 50A. The multi-pin configuration allows a different range of nominal currents by connecting 1, 2 or 3 pins in the primary winding.
The output signal is centered at 2.5V with an output voltage of ±0.625 V at nominal input currents, but the design allows detecting currents up to 3 times nominal current. It also provides a linearity <0.1% with a ±0.7% accuracy levels. Bandwidth is up to 150 kHz with a response time below 0.5us. Offset drift versus temperature is as low as 0.3% mV/ºC and consumption of the circuit is only 20mA 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.
It is fully compliant to below industrial standards:
- Isolated plastic case recognized according to UL94-V0
- EN 60947-1:2004
- EN 60950-1:2001
- EN 50178:1998
