With a focus on detecting both AC and DC residual currents, this cutting-edge solution ensures unparalleled safety standards for Mode 2 and Mode 3 EV chargers, aligning with European regulations. By utilizing Amorphous cores and a sophisticated self-excitation oscillation circuit, ZETTLER’s module boasts superior accuracy, with the ability to detect 3-6 mA DC differential current. Furthermore, its high surge-current withstand capacity of 3,000 A sets it apart from traditional products, offering engineers an exceptional solution for enhanced safety in EV charging systems.

Meeting the Surge of EV Demand

The global surge in electric vehicle adoption has led to a corresponding increase in the need for reliable and safe EV charging solutions. ZETTLER Magnetics is at the forefront of this shift, meeting the demand with its innovative EV-RCD module. This module is not just another product; it’s a response to the growing concerns over safety as the number of EVs on the road continues to rise. With more EVs, there are more charging sessions, and consequently, a higher risk of electrical faults. The EV-RCD module’s ability to detect nuanced variations in residual current and its robust surge-current capacity ensures that it can handle the uptick in EV charging activity without compromising on safety. This is crucial for maintaining consumer confidence and supporting the sustainable growth of the EV market. ZETTLER’s commitment to safety is thus helping to pave the way for the future of EV charging.

The Science Behind Leakage Detection

The EV-RCD module by ZETTLER Magnetics encompasses a sophisticated mechanism for identifying electrical leakages, a critical safety concern in EV charging systems. At the heart of this system lies the use of Amorphous cores that are highly sensitive to changes in magnetic fields caused by residual currents. When the electrical system operates normally, the sum of currents is balanced and no magnetic field is present. However, an insulation fault leads to an unbalanced current, creating a magnetic field that the Amorphous core detects. The module’s self-excitation oscillation circuit is then triggered, producing an oscillation waveform that varies with the magnetic field changes. This variation allows the module to precisely determine the type and magnitude of the differential current, sending a signal if it exceeds safety standards. This process ensures that any leakage, be it AC or DC, is promptly detected, maintaining the integrity and safety of the EV charging infrastructure.

Innovations in EV-RCD Technology

Superior Accuracy and Response

At the core of ZETTLER Magnetics’ EV-RCD technology is an unwavering commitment to accuracy. The module’s ability to detect differential currents as low as 3-6 mA is a testament to its precision, which is paramount when it comes to the safety of EV charging systems. Traditional leakage protection often falls short in accurately identifying DC residual currents, but ZETTLER’s module excels, ensuring that even the slightest deviations from normal current flows are detected and addressed. This heightened sensitivity is complemented by a swift response mechanism that communicates the presence of leakage currents promptly, allowing for immediate action to be taken. The module’s responsiveness not only adheres to but exceeds safety standards, providing an additional layer of security that is essential in today’s fast-growing EV market. This combination of superior accuracy and rapid response positions ZETTLER’s EV-RCD module as an essential component in the development of safe and reliable EV charging infrastructures.

Robust Design for Diverse Currents

ZETTLER Magnetics’ EV-RCD module is engineered to contend with a variety of current types, a feature that sets it apart in the realm of EV charging safety. The module’s robust design allows it to identify not just AC and standard DC residual currents but also the more elusive smooth DC residual currents that can occur during two-phase or three-phase rectification and filtering processes. This comprehensive detection capability is crucial for modern EV chargers that operate with complex electrical systems and various current types. By incorporating a design that can withstand the intricacies of these currents, ZETTLER ensures that the EV-RCD module delivers consistent performance and reliability, regardless of the charging scenario. Engineers can now design EV charging systems with the confidence that they are protected against a broad spectrum of electrical safety risks, thanks to ZETTLER’s innovative approach to leakage detection and protection.
