Premo has introduced a series of Hall Effect sensors called DSR5 series for a single supply voltage of 5V.
The sensor family is a close loop technology component in a small package for THT (through-hole technology) mounting. Primary winding is already integrated, which allows to measure DC, AC and pulse currents on printed circuit boards, says the company.
The sensors include an external pin that allows access to the internal reference of 2.5V. This pin can be used as an output or input signal to be used by microcontrollers providing offset control at zero current. The sensors have been designed for 6, 15, 25 and 50A currents. The multi-pin configuration is claimed to allow different range of currents by connecting 1, 2 or 3pins in the primary winding.
The output signal is centered at 2.5V with an output voltage of ±0.625V at input current. Bandwidth is up to 150kHz with a response time below 0.5µs. Offset drift versus temperature is 0.3%mV/ºC and consumption of the circuit is 20mA at no current condition.
The sensors are isolated with plastic housing, meeting isolation values of more than 3000V AC. They are compliant to an isolated plastic case recognised according to UL94-V0, EN 60947-1:2004, EN 60950-1:2001, and EN 50178:1998.
