p a g e | 10 AZSR180 This 80 A SPST high power PCB relay takes the well-known AZSR235/250 series to the next logical level. Developed for applications of up to 20 kVA (single phase) / 55 kVA (three phase). It features a patent pending 2 ) Thermal Bridge, designed to protect the paralleled contacts from overheating as a result of uneven distribution of currents. It is part of a series of ZETTLER relays that were specifically developed for alternative energy applications. • Wide contact gap ≥ 2.05 mm • Very low holding power < 100 mW • Reinforced insulation, EN 60730-1 (VDE 0631, part 1), EN 60335-1 (VDE 0700, part 1) • Dielectric strength 5000 V rms • Isolation spacing greater than 10 mm • UL, cUR file E44211 • VDE certificate 40044305 Figure 11: AZSR180 AZSR190 This 90 A standard version / 100 A “T”-version high power PCB relay is developed for PV applications but used in many high power charging applications also. • Wide contact gap ≥ 3.6 mm • Dielectric strength 5000 V rms • Isolation spacing greater than 10 mm • UL, CUR file E365652 • TÜV certificate B0887930008 Figure 12: AZSR190 2) International patent application pending (PCT/EP2015/076187)
p a g e | 11 3.3 ZETTLER AC circuit Relays for IEC mode 2 – Generation 2 charging AZEV116 The AZEV116 is a 16 A SPST relay and the entry level member of the AZEV116/132/140 series of SPST power PCB relay. With its specially formed contact set it is especially designed to withstand extreme short circuit currents without contact welding. Additionally, it features a potential free N.C. (1 Form B) monitoring supervisory contact as required by IEC62752:2016, thus making these types of relays ideally suited for applications with high security demands. Figure 13: AZEV116 • Wide contact gap ≥ 2.25 mm • Potential free N.C. signal contact for monitoring purposes • 1500 Amp short circuit current (carrying) • Holding power < 400 mW • Dielectric strength 4000 V rms (between Form A contact and coil) • UL, cUR file E365652 • TÜV certificate B0887930014 AZEV132 The AZEV132 is a 32 A SPST relay and the midrange member of the AZEV116/132/140 series of SPST power PCB relay. With its unique contact set arrangement, it is especially designed to withstand extreme short circuit currents without contact welding. Additionally, it features a potential free N.C. (1 Form B) monitoring supervisory contact as required by IEC62752:2016, thus making these types of relays ideally suited for applications with high security demands.
