Description

MT406 AC Voltage Transducer

Properties

  • Sinusoidal AC voltage measurements
  • Voltage range measurements up to 500 VL-N
  • Galvanic insulation between input and output
  • Accuracy class 0.5
  • Self powered
  • Housing for DIN rail mounting

Application

The MT406 voltage transducer is used for a permanent monitoring of a single-phase voltage value. PLCs, PCs, microprocessor control, indicators, alarms units etc. can be operated by the output signal. Voltage input can be connected either directly to low-voltage network or shall be connected to network via a corresponding voltage transformer (with standard 100V output).
