Medium Voltage HEMP Filters
With the risk of EMP, HEMP, and IEMI events, critical infrastructure needs the ultimate protection, which comes in the form of a brand-new medium voltage filter. The design generates less heat, has a total ownership cost that is less expensive, and has a smaller footprint than “stacked” low-voltage filter configurations.
TSS USA Manufacturing’s innovative medium voltage filters were designed with military-grade protection in mind, but electromagnetic pulse (EMP) and high altitude EMP (HEMP) events pose a risk across industries and applications.
Any facility operating with a medium voltage power distribution network is vulnerable to disruption, whether natural or manmade. Insufficient protection against such an event can lead to catastrophic system failures, electric blackouts, and costly downtime.
These are the first ever medium voltage HEMP filters, designed by our visionary team of experts drawing on decades of experience in EMI and EMP protection. Our filters are reliable, durable, and designed to last 15+ years.
Now you can protect your operations at a fraction of the cost, space, and maintenance needs of “stacked” low-voltage configurations. Filters are rated for 250A, 400A, and 800A at 4160VAC and for 5000 volts, with temperature rise 20°C. Just one TSS USA Manufacturing medium-voltage filter:
- Stops 5,000V Electromagnetic Pulses
- Small footprint
In addition to passing a five-year life test, this product line has met the following government and industry standards:
- UL1283 (in process)
- ISO 9001
- RoHS Compliance
- MIL-STD-461
- MIL-STD-220
- MIL-F-15733
And since critical protection calls for availability and quality assurance, TSS USA Manufacturing’s filters are all manufactured using predominately U.S.-sourced materials and meet the FAR 52.225-1 Made in America.
