Economical, Quiet, Compact Adaptive Multichannel Source (AMS) Provides 12 Analog Outputs with 16 bit Resolution
Test relays and other devices by simulating the waveforms from current or potential transformers, as presented to the internal analog input section of the devices under test. Using low-level analog signals reduces the cost, weight, power consumption, cooling and noise of test equipment that supplies high-level voltages and currents.
Digital I/O to Simulate Equipment and Monitor Test
The AMS includes six digital inputs to sense relay outputs and change test states. Use ten contact outputs to simulate station equipment, communications assisted protection points, and more.
State-Simulation Software For Flexible Testing
The included SEL-5401 Test System Software provides a virtual front panel, plus multiple states to simulate power system changes and faults:
- Sinusoidal outputs simulate steady-state conditions and changed-states.
- Amplitude ramping supports relay element threshold tests
- Frequency ramping simulates system events and tests frequency elements
- COMTRADE files or Mathcad® replayed through analog outputs.
- Digital inputs can change state to simulate equipment or system event
- Digital outputs programmed for each state simulate communications and equipment contacts
Complete Test Package
The AMS includes 24/48/125 and 250 vdc power supply , to power the equipment under test and the contact I/O. Cable harnesses for the equipment under test are included
