Integrating a new element into your infrastructure relies first and foremost on trust—especially if it is a safety measure for an entire network.

Trust matters too in that your infrastructure needs to pass its own set of system-wide quality control criteria. Decision makers need to feel confident they are receiving the highest quality product for their equipment.

Independent and universally recognized testing becomes a significant criterion when making modifications to electrical grids and communication networks. Independent testing raises the benchmark well above the minimum standards for safety and compliance to ensure customers are safeguarded against all unwanted interference and potential system failures.

UL 1283

UL 1283 is a standard published by Underwriters Laboratories (UL) that specifically addresses electromagnetic compatibility (EMC) for filtering devices used in electronic equipment.

While UL 1283 does not specifically mention High-altitude Electromagnetic Pulse (HEMP) or Electromagnetic Pulse (EMP) events, it provides guidelines for ensuring that electronic devices and systems are protected from various types of electrical disturbances, including electromagnetic interference (EMI).

Low-voltage filters from TSS USA Manufacturing have been certified, earning the ETL Listed Mark for this category. The mark confirms product compliance to North American safety standards. Filters certified to UL1283 have been independently tested and their manufacture must adhere to strict safety criteria.

To comply with UL 1283 standards, these low-voltage solutions against HEMP/EMP meet the requirements outlined in the standard. Some of its major provisions include:

Filtering and Shielding: Products must incorporate effective filtering and shielding mechanisms to minimize the impact of EMI on surrounding electronic equipment. This involves using appropriate internal parts and external filtering materials to prevent EMI from reaching sensitive components or systems.

Electrical Safety: UL-rated equipment adheres to stringent electrical safety standards to protect against potential hazards such as electric shock, short circuits, and fire risks. The product must demonstrate its safe performance in a similar system environment to that of its intended use.

Surge Protection: Electromagnetic radiation (EMR) from natural or manmade events can induce surges of energy in electrical systems and cabling. The TSS low-voltage solutions (suitable for 250V and 480V systems) are laboratory-tested on their susceptibility to surges. The test measures the efficacy of their own transient voltage surge suppressors (TVSS) to mitigate excess current running through the infrastructure.

Grounding and Bonding: Proper grounding and bonding techniques are critical to ensure the safe dissipation of electrical currents. Compliance with UL 467 (Grounding and Bonding Equipment) and UL 486A/B (Wire Connectors) are necessary to gain the mark of UL 1283.

Consult with the Experts

TSS USA Manufacturing has been a premier manufacturer of medium- and low- voltage EMP and HEMP filters and has implemented thousands of solutions for electronics and defense industries across North America.

The recent approval of the ETL from an accredited lab like UL confirms what we already know about the reliability and longevity of our safety solutions. We are proud to offer the highest quality solutions in order to assure our clients that they are choosing a proven strategy for maintaining safe and protected networks.

In some cases, for comprehensive protection against HEMP/EMP, specialized standards such as MIL-STD-188-125 or IEC 61000-2-9 may also be considered in conjunction with UL 1283 compliance.

If your organization seeks to protect its critical infrastructure, consulting with the experts at TSS will answer your questions about electromagnetic compatibility, electrical engineering, as well as compliance. We will determine the specific requirements and regulations in your jurisdiction and application domain.
