  • 500V DC Operation in a Small Footprint with Controlled Impedance
  • Up to 144 Channels in Two VXI Card Slots
  • SPST Relays can be Paired to Configure 12 DPST Relays per SMP2300
  • Fail-safe Interrupt Input on Front Panels for Emergency Fault Conditions

    The SMP2300 and SMP2300-93 are designed to switch high-voltage signals for device under test control and measurement purposes. The SMP2300 is designed to switch high-voltage signals in a controlled 50ohm impedance environment and the SMP2300-93 designed to switch signals in a controlled 93ohm environment.

    Up to 144 channels can be accommodated in a double-slot VXIbus card (SMP1200) for maximum density, or mixed and matched with other SMIPII™ cards for flexibility. Applications include Hipot or cable breakdown testing.

    When switching high voltages, the need for signal shielding becomes critical. The SMP2300 has been designed to include large shield planes to reduce crosstalk and voltage spikes to adjacent channels.

    For ATE applications, such as switching high-voltage source measure units or power supplies, a fail-safe interrupt line is provided on the front panel. This can open all relays automatically if a safety condition occurs. This approach instantly removes all high voltages to the UUT or interface.
