Independent Pulse-Current-Injection Test Results
Third-party test program evaluating four Ascentis candidate filter configurations across 480 VAC, 4.16 kVAC, and 13.8 kVAC applications, using methodologies derived from MIL-STD-188-125-1 Appendix B.
Testing Overview
Third-Party Pulse-Current-Injection Program
Scientific Applications and Research Associates, Inc. (SARA) independently tested four Ascentis candidate filter configurations using pulse-current-injection (PCI) equipment and methodologies derived from MIL-STD-188-125-1 Appendix B. All four candidate filters exceeded the program's greater-than-75% peak-current-reduction criterion.
The information on this page summarizes those results, the voltage classes tested, the methodology, and important qualifications. Detailed test reports are made available to qualified prospects under NDA.
Tested Voltage Classes

Two configurations
Tested in the power-off condition
One configuration
Summary Results
Reduction in E1-Related Current
Per-phase reduction values were measured at the 2,500 A PCI test level. Common-mode reduction values were measured at the 5,000 A PCI test level.
| Configuration | Per-Phase Reduction (2,500 A) | Common-Mode Reduction (5,000 A) |
|---|---|---|
| 480 VAC, power off | ≥95.5% | 89.3% |
| 480 VAC, power on | ≥96.8% | 92.1% |
| 4.16 kVAC, v7, power off | ≥95.3% | 89.2% |
| 4.16 kVAC, v8, power off | ≥95.4% | 88.0% |
| 13.8 kVAC, power off | ≥96.3% | 90.0% |
These results describe SARA testing of candidate filters. Final product configuration, sizing, placement, and facility integration are determined through an Ascentis engineering review.
