LEM click carries the LTS 6-NP current transducer and MCP3201 ADC converter. The click can measure AC and DC current with exceptional speed, up to 200 KHz. LEM click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over SPI interface, or directly with analog output.
DO NOT TOUCH THE BOARD WHILE THE EXTERNAL POWER SUPPLY IS ON!
Note: LEM click has exposed pins/pads. To stay safe take precaution when applying high voltage to the click. The click is to be used by trained personnel only when applying high voltage.
LTS 6-NP features
LTS 6-NP is a closed loop (compensated) multi-range current transducer using the Hall effect.
Intended for electronic measurement of currents: DC, AC, pulsed, mixed with galvanic separation between the primary circuit and the secondary circuit.
How it works
The circuit can be completed with the two screw terminals:
Or the conductor can be placed through the hole on the sensor:
There is on board ADC to read out the analog output value of the sensor, or it can be read from the AN pin.
MCP3201 A/D converter
The MCP3201 is a 12-bit Analog-to-Digital (A/D) Converter with on-board sample and hold circuitry. The device provides a single pseudo-differential input.
The MCP3201 is capable of sample rates of up to 100 ksps at a clock rate of 1.6 MHz.
