  • The accuracy 1% will not be affected when the CTs are mounted up to 2000 feet away from the meter.
  • DAE CTs are not direction sensitive. It does not matter if the contractors install the CTs with wrong direction of current. DAE meters can detect it and compensate it.
  • DAE provides both solid core CTs and split core CTs. Solid core CTs are suggested for new construction or for retrofitting construction when the power can be shut off. Split core CTs are ideal for retrofitting projects without having to disconnect wire terminations.
  • Factory Calibration Certificates available. DAE Controls LLC is a Minority Business. Please feel free to get the NMSDC Minority Supplier Certificate from DAE Controls Website.
  • Five year warranty from the seller and manufacturer.
