The continuous shortage of Hall Effect sensors is generating trouble for manufacturers such as those for PV and eolic inverters. So, Premo has introduced a family of Hall effect sensors which are equivalent to the LEM DHR-C420 family. The main characteristic of this series is the output current, which has a fixed range of 4 to 20mA. Such RMS sensing is the most accurate way to measure power supply and it is also used to indicate how a motor and load are operating. The rms function measures pulse signals. The developer has a completed family with input sensing currents from 20 up to 1,000 A.
The new series provides a linearity <0.5% with a ±1% accuracy levels. The bandwidth is up to 6kHz with a response time is below 200 ms. The offset drift-versus-temperature is as low as 0.5 µA/ºC and consumption of the circuit is only 30 mA at no current condition.
The units meet the following standards:
- Isolated plastic case recognized according to UL94-V0
- EN 60947-1:2004
- EN 60950-1:2001
- EN 50178:1998
