The Thermo Keytek ECAT E513 Surge Simulator is a plug-in module used with the Thermo Keytek ECAT Modular EMC Test System to produce voltage ramps for testing surge protection components, such as gas tube arrestors. Meets the surge simulator requirements of UL 864.


  • Controlled Open-Circuit Voltage Ramps of: 0.1kV/μs, 0.5kV/μs, 1.0kV/μs, 5.0kV/μs, 10kV/μs
  • Open-Circuit Voltage: to 3kV peak
  • Short-Circuit Current: to 50A peak
  • All test parameters under software control via KeyTek SurgeWare


Voltage Ramps: 0.1kV/μs, 0.5kV/μs, 1.0kV/μs, 5.0kV/μs, 10kV/μs, 0.1kV/μs is linear to 2.5kV; all other ramps linear to 3.0kV
(Note: Specified ramp rates are obtained with an open-circuit voltage setting of 3.0kV.)
Voltage Durations: ~65μs for 0.1kV/μs; ~40μs for 0.5kV/μs and 1kV/μs; ~5μs for 5kV/μs and 10kV/μs
Current Durations: ~45μs at 0.1kV/μs; ~40μs at 0.5kV/μs and 1.0kV/μs; ~5μs at 5kV/μs and 10kV/μs
Open-Circuit Voltage: 0-3000V ±5% in 1 volt steps
Short-Circuit Current: 50A, ±10% when the peak open-circuit voltage is set to 3.0kV
NOTE: To obtain linear fronts, waves are quasi-square waves with 20-25% initial overshoots beyond peak open-circuit voltages, except for the 0.1kV/μs which is roughly triangular. Undershoots range from 5 to 25%.
