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.

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.

American Zettler’s AZSR165 in a Hybrid-Solar-Inverter System with Scalable Battery Storage

Posted on by

Application Spotlight October 2018

Solar inverter solutions including scalable battery storage options are becoming increasingly popular.
One of the application challenges in these systems is to connect/disconnect the battery block to/from the inverter’s control circuitry.
A major clean home automation company approached Zettler seeking a solution that required switching of a 125 VDC battery while carrying load and charge currents of up to 50 Amps. Typically this would be an application scenario for high power DC contactors.
In close cooperation with customer engineering, Zettler’s team found an appropriate solution through reduction of the switching current down to 1.5 Amps by means of smart software controls. This measure fully enables AZSR165, a cost-effective solar AC relay, to fulfill the requirements of switching the DC path.
This elegant application-extension for one of many Zettler AC solar relays provided significant cost savings compared to the use of a DC contactor.
