Clamp On Current Transformer
AD-KSW


back to products

  Description

With the clamp on current transformers AD-KSW50, AD-KSW100, AD-KSW200, AD-KSW400 and AD-KSW600 high currents can be measured without contact in connection with the power measurement devices from the Adamczewski GmbH. There are transformers for the range up to 600 A AC available. By their small size they can be easily mounted on the current carrying conductors and can therefore be mounted easily to existing systems without disconnecting the main cable. The secondary side mA-currents are not critical and can be wired over several meters. By the internal voltage limitation there are no high voltages on the secondary side possible.

  Application

Measurement of high currents, power or energy in plants or buildings in connection with the measurement technology from the Adamczewski GmbH.

  Specific characteristics

  • non-contact measurement of high currents
  • no disconnection of the main cable during installation
  • uncritical mA-signals at the secondary side of the transformer
  •   Business data
