If you have ever read the term “programmable except for the supply on/off switch” the 90-200 can provide this capability in a system with the added benefit of an easy to use RS232 serial interface. The 90-200 is a power sequencer that provides a means of remotely controlling the power status of up to 8 instruments.

Each power outlet can be programmed to switched on in sequence with a specific timing delay. The delay can be staggered to ensure that order dependent systems - like PXI - can be switched on and off in an orderly way with just one operation. A staggered start up also limits the inrush current associated with the powering up of equipment, including earth current inrush, placing less stress on cabling and leakage breakers. Power on or off instructions can be initiated from either the front panel switch or via the serial interface.

  • Provides Controlled Start-up of Test Systems
