70 A solar power relay boasts compact footprint with optional welding monitoring for safest operation
The AZSR170 solar power relays from ZETTLER provide up to 70 A switching capability at up to 600 V ac with exceptional safety performance, making them suitable for solar inverter designs and high-voltage industrial applications.
The ZETTLER solar power relays are available in a compact 33.1 mm x 20.1 mm x 32.5 mm package for highest power density in the design with minimal PCB footprint. These relays have an SPST-NO configuration with an optional SPST-NC mirror contact for welding monitoring. This contact is compliant to EN 60947-4-1 standards.
The AZSR170 relay has a wide load contact gap of ≥3.0 mm, with ≥3.42 optional, which ensures excellent switching isolation despite the compact size, high voltage and current ratings. The contacts are composed of silver alloy with gold plating on the optional monitor contact.
The relays feature high dielectric strength at 5 kVrms and can withstand surge voltages up to 10 kV. The coil to load pin clearance is ≥8.0 mm, and these relays are TÜV, UL/CUR and CQC approved.
