LEM put the first small DC first-class precision DV voltage sensor on the traction market.
LEM electronics, the world's leading manufacturer of current and voltage measuring components, recently announced that it would launch DV series voltage sensors for measuring VRMs insulation voltage. The measurement of displacement of the experimental machine in the practice procedure is actually the measurement of large deformation of materials. After sales customers also saw the strength of our factory. This product uses LEM patented insulation technology. Its volume is much smaller than other similar products in the market today, and its overall dimension is only 134x54.22x147.25mm
dv series voltage sensors have been developed and put into production according to the international rail industry standard (IRIS). Now, engineers in the railway industry (including rail vehicles and sub stations) use new sensors for measurement. He added that the company will also discuss the development blueprint after 2015 at the investor conference to measure the network voltage and the DC connection of the main inverter of the train. The product is also applicable to the industrial market of high-voltage and medium voltage measurement
due to its low current consumption of Ma, large frequency bandwidth of 12khz and safe insulation voltage of 18.5kv, LEM's DV voltage sensor meets the requirements of modern railway system and all new EMC requirements. In addition, other main features include high partial discharge arc extinguishing voltage, compliance with safety standards, high-quality friction and wear tester [back to the catalogue] and long life, as well as light weight and flexible mechanical and electrical output suitable for customer needs
the development trend of products in the railway market is to save space and improve performance. On the other hand, in order to ensure safety and better insulation with external electric, magnetic and electromagnetic fields, so as to achieve EMC protection, various latest standards put forward higher and higher requirements for higher insulation and partial discharge arc extinguishing levels. L
em's DV series voltage sensors are designed to meet these conflicting needs
dv has a first-class certification level, so it is suitable for applications such as energy measurement. The materials used meet the mandatory fire and smoke prevention requirements in Railway applications. The DV voltage sensor is CE certified and has a five-year warranty like all LEM railway products
