ZETTLER AZSR165 Series Relays for E-mobility Wall Box Charger Applications
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 for these types of applications.
ZETTLER 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 65A (carrying) and 100k switching cycles （Making 10A, Carrying 65A, Breaking 10A，@480VAC, Res.）, the 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 90A rating and 100A as a high current version AZSR190T.
For e-mobility 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 (20A at 277VAC on, carry 50A, 20A 277VAC off, Res.) or AZSR131 with TüV approved rating up to 33A 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.
