E-AMP400-SC12: Hall-effect current sensors, split-core, 0.47" (12mm) loop diameter 

measures both AC and DC currents using a split-core system; compatible with ENVIROMUX® E-ACDCLM and E-DCLM-6 

Includes a 7 foot 4-wire cable for connecting to E-ACDCLM or E-DCLM-6.

To extend the distance between the hall-effect sensor and E-ACDCLM or E-DCLM-6, simply connect longer wires (22AWG) using the included splices. It is recommended to place E-ACDCLM or E-DCLM-6 as close to the hall-effect sensor as possible. E-ACDCLM and E-DCLM-6 can be placed up to 1000 feet away from the ENVIROMUX 2D/5D/16D unit using CAT-5/5e/6 cable.

Common applications include monitoring AC variable speed drives, static converters for DC motor drives, battery supplied applications, uninterruptible power supplies (UPS), switched mode power supplies (SMPS), electrochemical systems, and power supplies for welding applications.
