A 50A power relay for solar / EV charging applications with a very small footprint.
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 (click here for more info).
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.
- Dielectric strength 4.5 Vrms
- Contact gap 1.8mm
- Class F insulation system
- UL, CUR, and TUV approvals
Innovation in product design is how ZETTLER is leading the field of new energy application solutions. Other relay products in that category include:
