*
kV version is required for operation with surge modules greater than 7kV,
such as the E510A. All standard coupler/decoupler options apply
|
|
** Actual current capability may be limited by the AC line connectors selected
|
|
*** Depends on connector selected. Typically 15A with U.S. NEMA connector; 16A with appropriate European style connectors
|
|
Coupling Mode
|
Coupling mode selection is controlled manually from the control Selection center, or automatically using KeyTek SurgeWare™ or BurstWare™ software. Coupling is allowed from any line to any other line or combination of lines.
|
|
Monitoring
|
Monitoring and peak detection of surge voltage across any two manually-selected lines. Monitoring can be at the EUT or at the front panel of the coupler/decoupler.
|
|
|
Monitoring and peak detection of surge current in either High or Neutral, selected by the ECAT Control Center or the computer, measured without including back-filter surge current.
|

E455x-VI
|
Enhanced V and I monitoring. Adds monitoring and peak detection of Surge voltage and current. Upper and lower limits can be placed on surge peaks. Monitoring of 3 wires is provided in single-phase systems, 5 wires in three-phase systems. Selection of the V and I inputs is performed from the control center or can be made automatically with SurgeWare control software
|
|
E455x-HV
|
Increases the AC mains voltage rating from 277V to 480V rms in the E4552, and from 480V to 600V rms in the E4553 and E4554. The HV option is not available in the E4551, E4555 and E4556.
