Power Switches 19AMX

Universal Digitally Controlled Analog Switches/Multiplexers

General Technical Data for all Switches


  • 1–4 independent, digitally controlled, galvanically isolated electronic analog switches


  • Polarity selection: jumpers inside the device or jumperless digital control


  • Control Inputs: BNC sockets (LEMO optional)
  • Input level: TTL
  • Switch terminals: SHV sockets (BNC optional), galvanically isolated


  • Temperature monitoring, automatic shutdown at excessive temperatures
  • Line input: universal 90–250 V, 50–60 Hz
  • Case: 19" case "Multipac Pro", rack-mount
  • Height: 3 U
  • Depth: 220 mm

Equivalent Circuits

Dual-level switch:

  • Equivalent circuit of one two-level channel
  • Vneg ≤ Vout ≤ Vpos must be fulfilled at all times (even when the switch is deactivated)

Three-level switch:

  • Equivalent circuit of one three-level channel
  • Vneg ≤ Vout ≤ Vpos and Vneg ≤ Vmid ≤ Vpos must be fulfilled at all times (even when the switch is deactivated)
When a channel is deactivated, all relay contacts are opened. The dual-level switch therefore has 3 and the three-level switch has 4 possible states.
