ZETTLER introduces new 50A power relay for solar / EV charging applications with very small footprint.

Posted on by
Product announcement, April 2020.
The demand for switching higher currents and higher voltages on increasingly smaller footprint continues to grow, especially in Solar and EV charging applications. ZETTLER is following this trend by introducing its newest type of “New Energy” relays, the 50A AZSR143.
With a footprint of only 30.4mm x 15.9mm the AZSR143 closes the gap between the well-known AZSR131 and AZSR235/AZSR250.
The AZSR143 has a maximum UL/TUV switch rating of 50A@277VAC with 6K cycles. Other ratings include 43A@277VAC (85°C) and 33A@277VAC (105 C) with 30K cycles each and 50A@277VAC carry current with 50K cycles (on/off) at 20A. It features a 1.8mm contact gap, a 4500Vrms dielectric strength and a minimum holding power of 196mW.

Mainly designed for solar inverters, the AZSR143 is also well suited for for electric vehicle charging equipment.

Posted on by

Application Spotlight, February 2020.

Global plug-in electric vehicles sales for the first half of 2019 reached more than 1.1 million units- a 46% increase over prior year. Estimated global sales for 2020 are projected to reach 4 million units, reaching 12 million units in 2025, and 21 million in 2030.
AZSR131 relays from ZETTLER for use in E-mobility wallbox chargerThis positive trend is also evident in associated sales of charging infrastructure solutions. In particular, wall charging stations – so-called “wallboxes” – that enable EV charging with AC voltage according to charging mode 3 (IEC 61851-1) are and will continue to be in extraordinary demand. They facilitate charging of electric vehicles with voltages up to 400V, and are used in protected areas such as parking garages, carports or private homes.
ZETTLER AZSR131 EV charging relay
A supplier of wallboxes contacted ZETTLER in Europe, because of their need for a relay compliant with the requirements of IEC 61851-1 for a new generation of EV charging wallboxes. The relays of ZETTLER’s AZSR131 series have a normally open contact (1 form A) and are UL and TÜV approved with 35A 277VAC and 30,000 switching cycles or 33A 277VAC and 50,000 switching cycles with TÜV. The relays are available in the standard version with 1.8mm contact gap and in a special version with up to 2.3mm. The relays are also available in a version in accordance with the extended household appliance standard IEC 60335-1 (GWT). This component solution in the EV charging space along with others, such as the new AZEV132 EV charging relay, keeps ZETTLER relays at the forefront in this significant green energy growth segment.

New ZETTLER relay series AZEV116 / 132 meets stringent requirements of IEC62752 for Mode 2 charging of Electric Vehicles (EV).

Posted on by

November 2019

Electromobility is progressing steadily and the plans of many car manufacturers to ultimately exit internal combustion engine technology are becoming ever more concrete.
American zettler relays for relay for EV charging systems

As with almost all emerging technologies, application-specific standards for EV charging have continuously evolved over the years as safety concerns and impacts to the electric utility grid were considered. For early pioneers of electrical vehicle supply equipment (EVSE) or charging stations, this meant constant re-engineering of existing systems to meet regional standards and uncertainty around future certification requirements.

For the charging of electric vehicles using household or CEE sockets, the IEC62752 standard offers system designers a welcome sense of clarity on what future regulations are likely to require. Charge mode 2 (Level 2 charging / IC-CPD) addresses necessary control and safety requirements for charging cables along with considerations for the type of currents and service life these products will endure.
American Zettler AZEV116 and AZEV132 relays

Fortunately for hardware designers of EVSE systems, ZETTLER’s new relay series AZEV116 and AZEV132 were developed specifically for use in accordance with IEC62752 and, more importantly, to meet the exceedingly stringent short-circuit withstand-current requirements of this standard. These relays also have an isolated signal monitoring contact to allow detection of any possible welding issues with the main contacts.

Highlights:

  • Designed for charging systems of charge mode 2 (IEC62752).
  • Normally open (1 Form A) with wide contact gap ≥ 2.25 mm.
  • Dielectric strength (coil/power contact) 4,000 Vrms.
  • Galvanic isolated signal monitoring contact (1 Form B).
  • UL, CUR and TUV approvals.

AZEV116:

  • Electrical lifetime: 50,000 switching cycles 16 A, 277 VAC @ 85C
  • Short-circuit withstand: ≥ 1.02 kA; ≥ 2.5 kA²s

AZEV132:

  • Electrical lifetime: 50,000 switching cycles 32 A, 277 VAC @ 85C
  • Short-circuit withstand: ≥ 1.5 kA; ≥ 6.0 kA²s

ZETTLER introduces high-capacity PCB mount solar relays optimized for 690VAC grid inverters.

Posted on by

Product Spotlight, May 2019.

For the switching of 600VAC-800VAC circuits, large contactors have traditionally been the only viable option but new high capacity relays from ZETTLER are challenging those assumptions.
The new AZSR1160 and AZSR1180 PCB mount relays from ZETTLER provide system designers with a small form-factor alternative for switching power levels up to 165kVA. These new SPST relays can switch voltages up to 920VAC and currents up to 180A, all with a holding (coil) power of less than 0.5W. Contact gaps and insulation distances are optimized for commercial PV systems deployable up to 7000 m above sea level.
Key Features or Design Parameters include:

  • Specially designed terminals simplify thermal management and maximize lifetime
  • 3.6mm contact gap available
  • >10mm clearance/creapage
  • High surge breakdown voltage of 10kV
  • Coil voltage options from 6-48VDC
  • UL and TUV ratings

ZETTLER introduces a number of new relays at 2018 Munich electronica

Posted on by
Focusing on solar, e-mobility and multiple other applications, ZETTLER Group will showcase various new relays at this year’s November electronica show in Munich, Germany.
The new AZEV116 and AZEV132 series are next-generation IEC mode 2 Electric Vehicle (EV) charging relays in development for release in 2019. These relays are designed to survive high momentary currents that may occur on short circuits, thus ensuring outstanding reliability without contact welding. The AZEV116/132 series will also feature a potential monitoring contact, as required by IEC62752:2016, making these types of relays ideally suited for EV and other applications demanding high security and safety demands.
The newly developed AZSR1160 is a 160 A extreme high-power PCB Solar Relay, designed for PV applications of up to 36,8 kVA (single phase 230 VAC) / 111 kVA (three phase 400 VAC) – a highly attractive, small footprint substitute for conventional contactors. This relay is suitable for large commercial / rooftop-based PV systems and commercial solar fields.
AZSR190 is a 90 A high-power PCB relay for solar inverters. Developed for PV applications of up to 23 kVA (single phase 230 VAC) / 69 kVA (three phase 400 VAC) this relay is well suited for medium sized to larger roof top-based / commercial systems.
AZSR165 is a 65 A economy version of the new AZSR190 series. Developed for PV applications of up to 18,4 kVA (single phase 230 VAC) / 55 kVA (three phase 400 VAC) this relay is well suited for medium sized to larger roof top-based / commercial systems. ZETTLER recently also adapted this relay for a DC-side solar battery storage application, supporting a major industry player in clean home-energy solutions.
ZETTLERs AZSR131 was initially designed as a solar relay for residential and small roof top-based PV systems of up to 8 kVA (single phase 230 VAC) / 24 kVA (three phase 400 VAC). While not a new relay, ZETTLER continues to find new application extensions for this relay beyond just PV solar inverters. AZSR131 is suitable for diverse applications such as heat-pump solutions and Electro Vehicle wall box charging units and is, therefore, rapidly becoming a multi-purpose relay.
AZDC6 is a 600VDC miniature relay for RSS (Rapid Shutting Down System) for Solar installations, scheduled for 2019 release. The compact size allows for a thinner design of certain RSS boxes, that are deployed as part of compliance with 2017 NEC 690.12.
