Line Monitor
LE-170SA
-
LE-170SA is a compact hand-held size line monitor for CAN/LIN. It has a touch screen and can be control as for smartfones. It has 1 CAN channel and 1 LIN channel and it can monitor both CAN and LIN communication thus monitoring of the network which has both CAN and LIN is available. The monitor function can diplay the communication data in real-time while saving it. The simulation function can send/receive the test data instead of the original communication partner. The ID filtering and trigger function make your development/evaluation more efficient. It also can measure 4 external signals as degital signals or analog signals while monitoring the communication data.It is light (300g) and convenient for field testing. The line monitor is useful for not only development but also maintenance.

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
