Quality Electronic Components for Power Electronics Applications


Model # NCS125T-10AF

  • These current sensors are specially designed and manufactured for Traction applications (NCS range for fixed railway applications and CS range for rolling stock).
  • The requirements for these sensors are generally higher than those for Industry applications (larger operating temperature range, higher level of shocks and vibrations).
  • These sensors can be fixed mechanically, by the case or by the primary bar, depending on the version or option.

FeaturesGeneral Data Plastic case and insulating resin are self-extinguishing. Two fixing modes : Horizontal or vertical with fixing holes in the case moulding. By bar using the intermediate flange kit. Max tightening torque for M6 screws (flange mounting): 2 N.m. Direction of the Current : Output current (IS1 and IS2) : A primary current flowing in the direction of the arrow results in a positive secondary output current on terminals IS1 and IS2. Output voltage (VS1 and VS2) : A pr
DetailsFixed Installations 100% electronic The main advantage of the NCS range of sensors is that they are designed using a brand-new solution : 100% electronic technology. Unlike other currently available solutions such as shunts and CTs, this approach means that these sensors are very compact. Several patents were necessary to achieve this improvement. Considerable energy savings NCS sensors offer considerable savings in energy. Indeed only a few watts are required to power the NCS se

5S Components Co.

5S Components Inc is a result of a management buyout of ABB Semiconductors Inc. by John Siefken and Kenny Stephenson. Effective December 1, 2005, 5S Components became the successor to ABB Semiconductors Inc. Kurt Hoerhager, Managing Director of ABB Switzerland Semiconductors and Roland Villiger, Director of Sales, commented that “Creating 5S guarantees focus on semiconductor sales in North America, a vital part our growth strategy.
