\"\"<\/p>","protected":false},"excerpt":{"rendered":"

The BY81 series intelligent capacitors combine measurement and control technologies, employing synchronous switching for precise control, eliminating jitter, and extending service life to one million cycles. They offer high reliability, low failure rate, and low power consumption. Their rational compensation methods and full-featured design provide superior performance, including advanced power analysis capabilities, and can be equipped with various peripherals. Multiple units can be modularly combined, automatically generating a master unit and switching automatically in case of faults, featuring highly intelligent and intuitive operating status displays. There is no inrush current during shutdown, zero-crossing switching avoids over voltage, breakdown, arcing, and impact. Their comprehensive measurement and protection functions cover temperature, harmonics, phase loss, and three-phase imbalance protection.<\/p>","protected":false},"featured_media":1318,"template":"","meta":{"_acf_changed":false,"_gspb_post_css":""},"product_brand":[],"product_cat":[36,35],"product_tag":[],"class_list":["post-1292","product","type-product","status-publish","has-post-thumbnail","product_cat-intelligent-capacitor","product_cat-reactive-power-compensator","first","instock","shipping-taxable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/product\/1292","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/media\/1318"}],"wp:attachment":[{"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/media?parent=1292"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/product_brand?post=1292"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/product_cat?post=1292"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/cnbygele.com\/vi\/wp-json\/wp\/v2\/product_tag?post=1292"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
