\u25a0The three-phase intelligent rail meter measures active and reactive power in both forward and reverse<\/p>\n

directions. It simultaneously monitors A, B, and C phase voltages, currents, active\/reactive power,<\/p>\n

power factor, grid frequency, and total power consumption, with maximum demand recording<\/p>\n

capability. The meter stores cumulative data for active\/reactive power, forward\/reverse total, peak,<\/p>\n

valley, and flat periods, with the multi-rate billing function available only in high-capacity models.<\/p>\n

\u25a0You can set two time zones and two schedules per year, eight daily periods and four rates:<\/p>\n

peak, peak, flat and valley. The minimum interval between periods is 1 5 minutes.<\/p>\n

\u25a0The system features data wheel display and data key display functions. Users can access voltage, current,<\/p>\n

power factor, frequency, active power, reactive power, forward\/reverse active energy, and forward\/reverse<\/p>\n

reactive energy through panel buttons. If no button is pressed within 8 seconds, the system automatically<\/p>\n

switches to 4-second wheel display mode.<\/p>\n

\u25a0Optional display of maximum demand for U, I, P, and Q, along with total peak, valley, flat, and off-peak power consumption for active and reactive power.<\/p>\n

\u25a0Features active and reactive power pulse outputs for meter calibration and remote energy<\/p>\n

collection. The passive opto-isolated output port delivers a pulse width of 80ms \u00b1 20ms.<\/p>\n

\u25cfThe clock error is less than 0.5s per day, with automatic switching of calendar, timing, and leap year.<\/p>\n

Product Introduction<\/strong><\/p>\n

The device features 35mm standard rail mounting with a remote RS-485 communication interface, meeting all<\/p>\n

technical requirements for electricity meters specified in GB\/T17215 and DL\/T614. It utilizes DL\/T645-2007<\/p>\n

protocol compatibility with MODBUS-RTU to enable data exchange with host computers, facilitating energy<\/p>\n

measurement, power consumption monitoring, data visualization, and remote transmission. Widely adopted in<\/p>\n

smart buildings and enterprise-level energy management systems, it supports operational assessment and control.<\/p>","protected":false},"featured_media":2894,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[34],"product_tag":[],"class_list":{"0":"post-2893","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-smart-electricity-meter","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product\/2893","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/comments?post=2893"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/media\/2894"}],"wp:attachment":[{"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/media?parent=2893"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product_brand?post=2893"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product_cat?post=2893"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product_tag?post=2893"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
