ZETTLER Relays – Application Spotlight, April 2020.

The demand for switching higher currents in electric vehicle (EV) charging applications is increasing rapidly. ZETTLER relays, specifically designed for “New Energy” purposes,are especially suitable in these types of applications.

ZETTLER’s AZSR165 relay series are 1-pole high-power PCB relays, initially developed for solar inverter applications. With a UL, CUR and TÜV approved rating of up to 65 A (carrying) and 100k switching cycles (Making 10A, Carrying 65A, Breaking 10A, @480VAC, resistive), these relays are also suitable for EV charging in IEC mode 3 with the requirements of at least 50k switching cycles, according to the IEC61851-1 standard.

The AZSR165 series is the economy version of the ZETTLER AZSR190 series that features a 90 A rating  and 100 A as high current version AZSR190T.

For wall box chargers with a lower charging capacity, the  ZETTLER  AZSR143  relay series with a UL, CUR and TÜV approved rating of up to 50 A (carrying) and 50k switching cycles (20 A at 277 VAC on, carry 50A, 20A 277VAC off, resistive) or AZSR131 with TÜV approved rating up to 33 A with 50k switching cycles can alternatively  be used.

In addition to relays, ZETTLER Group also manufactures magnetics and transformer components such as current sensors, as well as a broad line of LCD and TFT displays.

ZETTLER Relays – 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 loop between the well-known AZSR131 and AZSR235/250.

The AZSR143 has a maximum UL/TUEV switch rating of 50A@277VAC with 6K cycles. Other ratings are 43A@277VAC (85°C) and 33A@277VAC (105°C) with 30K cycles each and 50A@277VAC carry current (20A switch on/off) with 50K cycles tested. 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 applications in the realm of electric vehicle charging equipment.

Innovation in product design is how ZETTLER is leading the field of new energy application solutions. Please also ask us for other relay products in that category, such as the 16/32A AZEV116/132, the 65/90A AZSR165/190 or our 35A AZSR131 as well as our flagship solar relay, the 50A AZSR250.

In addition to relays, ZETTLER Group also manufactures magnetics and transformer components such as current sensors, as well as a broad line of LCD and TFT displays.
