C252

25A Dual Channel Hall Effect Current Sensor Module

The C252 Current Sensor module has two hall effect current transducers that measure up to 25A DC (bidirectional) on each channel. Each channel is measured with a 12-bit analog to digital converter, giving readings of an accuracy of about 20 mA over the full range of 50 Amps (25 in either direction). Digital low pass filtering is used to average the value to reduce noise.

This module is typically used to measure solar energy produced on channel and load on the second channel. Multiple modules can be integrated into a single Wattmon setup when measuring additional sources such as wind or multiple panels or loads.
