Application 4P 1500V 35A Z3BENV BYSS Series DC Isolator is application for 1000V, 1500V commercial system or solar ground. Up to 35A at 1500V, 50A at 1000V. As the solar panels current rating increasing, the solar PV systems require higher voltage and current rating isolators. ZJBENY developed compact BYSS-50 for solar commercial systems and solar ground.
