A new smart energy monitoring sensor from Melexis has been introduced that can be used for clamp-on measurement in a range of applications.
Dubbed MLX91218-LF, the hall current sensor is designed for lower current applications. This includes smart energy monitoring in:
- Resident power distribution units
- Industrial power distribution units
- Micro-grids
- Electric vehicle charging cables
Energy monitoring is used to enhance the efficiency of electronic circuits. The data collected by power supplies and advanced metering infrastructure allow vendors to change the way energy is used while minimizing waste. This could also improve strategies to manage peak demand and consumption.
Many of these applications where the MLX91218-LF is applicable include non-intrusive current monitoring of up to 100 amps. The sensor features a 400 kHz bandwidth and a 2 µs response time for small current changes to be detected at high speeds. It also includes low thermal drift across a wide temperature range, high linearity and low noise, Melexis said.
