6.5.10 LEM 6 3-6 Channel Interface
Connection Diagram
The N4L LEM-6 Interface serves as a high accuracy, highly stable interfacing unit
allowing simple "plug and play" connection of any N4L PPA to the LEM current
transducers listed in table 1.
The LEM-6 supplies the LEM transducer with a highly stable isolated supply
voltage; each channel is isolated from the next providing excellent cross channel
coupling immunity. There are 4x current shunts per channel, 1Ω, 2.5Ω, 5Ω &
10Ω; this ensures the transducer can be utilized accurately throughout its
dynamic range without the introduction of noise into the measurement.
The LEM-6 is 19 inch rack mountable and available in 3 - 6 phase configurations.
