Zero Surge Inc. introduces the "FF1 Series" family of surge suppression products delivering branch circuit power-surge protection for commercial and industrial applications, including whole rooms ...

The circuit is designed to be constructed in a small module structure with an onboard electromagnetic relay as the primary switching device. The design is centered around (again) the famed 555 timer, ...

Applications include whole rooms, entire 20 amp branch circuits, and sensitive electronics. FF1 Series surge filters have never experienced any surge-related failures, fires, downtime, or recalls.

Based on the simplified circuit, a significant reduction can be made in the number of the protective components. For examination of the validity of the circuit simplification, an impulse experimental ...

An effective design method of surge protection circuits for an active EMI filter (AEF) is proposed. The overcurrent and overvoltage at the voltage-sense voltage-compensate type AEF due to a surge is ...

This paper introduces two surge generation circuits designed to comply with the IEC61000-4-5 standard. Leveraging these circuits, we conduct a comprehensive investigation into the impact of surges on ...
