TMCM-0013-xA
Document Revision V1.00 • 2019-Sept-12
TMCM-0013-2A/-3A/-6A Description
The TMCM-0013-xA boards are tools to simplify mea-
surement and visualization of 2x motor phase currents
of small electric motors such as stepper motors, BLDC
motors, or DC motors without the need for an expensive current probe. They are easy to use and can be
connected to typical laboratory oscilloscopes.
• Supplied via USB or dedicated laboratory power
supply with +7. . . +35V.
• Comes in 3 different current measurement ranges
(nominal range).
• Connects to a scope via SMA-2-BNC cables or standard probe clamps.
INTERFACE BOARD & LAB TOOL
• Easy to handle screw terminals and USB-C.
• Uses galvanically isolated current transducers
LEM LTS 6-NP (https://www.lem.com/en/lts-6np).
