Comparator MX-404

Product
Sound phase comparator for VDS/VIS. Device to establish concordance between two phases, designed for high- and medium-impedance capacitive voltage dividers (HR-MR). Suitable for connection to test points of VIS or VDS indicators or their interfaces. Not compatible with Schneider Electric type V2 cells.

Application

• Establish concordance relations between two phases.
• Connects to test points of VIS or VDS indicators or their interfaces; interoperable with indicators such as CL-495-3 and CL-497-00.
• Operates with separable capacitive voltage dividers (HR-MR).
• Not suitable for Schneider Electric type V2 cells.

Features

• Designed for high and medium impedance voltage dividers (HR - MR).
• Indications on connection:
  • Audible signal when a significant phase shift exists between the two phases.
  • No audible signal and illumination of the green LED when phases are in concordance.
• Degree of protection: IP20.
• Probe protection: IP2X.

Standards
IEC 61958 / IEC 61243-5
