ZETTLER Introduced 50A AZSR143 Power Relay for Solar EV Charging Applications with Very Small Footprint
The demand for switching higher currents and higher voltages on increasingly smaller footprints continues to grow, especially in Solar EV charging applications. ZETTLER is following this trend by introducing its 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℃) and 33A@277VAC (105C) 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 electric vehicle charging equipment.
Innovation in product design is how ZETTLER is leading the field of new energy application solutions. Please also Contact Us for other relay products in that category, such as the 16/32A AZEV116/AZEV132, the 65/90A AZSR165/AZSR190, or ZETTLER 35A AZSR131 as well as ZETTLER flagship solar relay, the 50A AZSR250.
