The Hall effect sensor meets the highest safety requirements and is isolated with plastic housing, meeting isolation values higher than 4,000 Vac.

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
