Overview

Model 20-340 High Voltage Guarded Multiplexer module will switch up to 1500 Volts with an Insulation Resistance of over 100T Ohms. Available in 16 or 24 channel versions, automatic isolation switching minimises leakage in large multiplexer systems. The 20-340/341 is designed to operate with high performance Insulation Resistance Meters such as the Sefelec M1500P Programmable as a conventional break-before-make multiplexer or in multi-channel mode where any combination of charge or measure channels may be selected simultaneously.
These units are designed for both “hot ” switching ((close switch after load applied) and “cold ” switching (close switch before EHT load applied) high voltage applications, giving very reliable switching with no disruption to internal logic. For large multiplexer systems automatic isolation switching connects only those multiplexer banks which contain active channels

Key Features

  • High Density HV Multiplexer with Choice of 16 or 24 Channel Versions
  • Switch up to 1.5kV with 2kV Standoff Voltage
  • Automatic Isolation Switches Minimise Capacitive Loading and Leakage Current in Large Systems
  • Very Low Leakage Currents When Using Driven Guard
  • High Quality Reed Switch Contacts for Reliable Switching with Long Life
  • Insulation Resistance >100T Ohms
