8080 HEMP powerline filters
The 8080 HEMP powerline filters of Holland Shielding Systems are designed to withstand the PCI test known as E1, E2 and E3 while largely exceeding the shielding effectiveness as stated in MIL-STD-188-125.
Our R&D specialist designed and the filters you meeting the highest shielding demands with an insertion loss of 100dB @9kHz and 120dB @20kHz.
All our filters are tested with our in-house E1/E2 testing facility to confirm that they meet our high quality demands.
As the only powerline filter supplier in the world that has an E1 and E2 pulse tester in-house, we have the possibility to develop test and supply the filters with a short delivery time.
- 230V/440Vac with 16A – 200A current ratings (others on request)
- Single or three phase applications
- Up to 100dB @9kHz
- Very low residual pulse current
- Quick development and delivery possible with our in-house testing facility

Insertion loss and E1, E2 and E3 pulse testing facility
As only filter producer we can perform individual pulse testing, to guarantee that your filter will protect your facility and not just on paper. Our filters are tested with our in-house test facility with which we are capable to perform PCI as per E1 (20/500ns 2.5kA peak) and E2 (1.5/4000µs 250A peak) test pulses. With our testing facilities we make sure that our filters comply with the highest demands and that the residual currents are within limits of the applicable standards and norms.
The intense electromagnetic pulse (EMP is generated by the phenomenon called “Compton effect” or “Compton scattering”. The nuclear explosion that generates this transient electromagnetic disturbance is also know as NEMP (Nuclear Electromagnetic Pulse) or HEMP (High altitude Electromagnetic Pulse). The HEMP is typically defined as a combination of three consecutive pulses called early time (E1), intermediate-time (E2), late-time (E3), as shown in the graph below.
