American Zettler: See their Wide Range of Power Relays

Your power needs met from A to Z

American Zettler’s power relays are known for their reliability, durability, and versatility in various applications, including industrial machinery, automotive systems, HVAC (heating, ventilation, and air conditioning) equipment, telecommunications, and more. They offer a range of power relay products suitable for different voltage, current, and load requirements. In addition, the Zettler group also offers Power Transformers as well as AC/DC Power Modules to fit all your power needs.

Solar Power and EV Charging

American Zettler has expanded their relay range with the AZEV series to meet the needs of electric vehicles and their charging infrastructure. The AZEV series, for example, provides a solution to survive highest momentary currents, as they may occur on short circuits. These types of relays ideally suited for applications with high security and safety demands. Contact welding or malfunction can thus be easily detected and indicated.

The AZSR series plays a significant role in solar power systems, providing essential switching functions with high reliability and efficiency. These wide gap relays are well-suited for various applications within solar energy systems, meeting safety requirements for protecting linemen during power outages.

The AZSR series is most suitable for applications across industries such as industrial automation, HVAC systems, lighting control, motor drives, and renewable energy systems, ensuring optimal performance and longevity in demanding environments. On the other hand, the AZEV series relays are versatile and reliable components for IEC EV charging applications.

ZETTLER was one of the first manufacturers to have successfully developed and produced a 35 amp and a 50 amp PCB solar relay with a footprint of just 25mm x 40mm.

As pertinent safety standards such as IEC 62109, UL 62109 and DIN VDE V 0126-1-1 gradually evolved and internationally converged, additional capabilities of solar relays deployed in solar inverter applications became necessary to fulfill ever higher isolation requirements, which, in turn, continued to raise the bar, especially with respect to wider contact gap.


Power Transformers

When understanding the importance of Power Relays, we can also assume Power Transformers play a critical role when controlling and managing the flow of electrical power in various electronic systems and applications. Power Relays and Power Transformers work together in various applications to provide efficient and reliable operation within electronic systems.

The BV series is a series of cost effective, Class 2 recognized encapsulated power transformers – suited for applications in LED Lighting, Electric Metering, Motor Controls, Thermostats and other similar fields. View Zettler Magnetics here
