\u25a0Electricity metering features: Separate measurement of forward and reverse active and reactive power phases, with active power at<\/p>\n

0.5-level and reactive power at 2.0-level. It supports total, peak, off-peak, flat, and valley rates, along with maximum demand<\/p>\n

measurement.<\/p>\n

\u25a0The electrical parameter measurement function monitors active power, reactive power, apparent power, real-time voltage, and power factor in real time. It monitors voltage and current in real time, determines voltage loss and starting current threshold, and performs sound and light alarm and event recording.<\/p>\n

\u25a0Alarm function: When the electricity meter has alarm events such as loss of voltage, loss of current, reverse phase sequence, overload,<\/p>\n

power reversal, battery under voltage, cover opening, or receives remote alarm command, the indicator light and buzzer will alarm, and the alarm relay signal can be output, and the cover can be closed or removed.<\/p>\n

\u25a0Power-off control: When the remote management system issues a power-off or power-on command, the electricity meter automatically cuts off the user’s load or restores power usage.<\/p>\n

 <\/p>\n

Household electricity<\/strong><\/p>\n

\u25a0Data freezing function: It supports timed freezing, instant freezing, scheduled freezing, and daily<\/p>\n

freezing through communication ports. Data can be read via RS485 or infrared communication ports.<\/p>\n

\u25a0Event logging: Records the last 10 events, including programming, reset, time synchronization, phase voltage loss,<\/p>\n

phase disconnection, phase current loss, current imbalance, reverse phase sequence of voltage and current, cover<\/p>\n

opening, and overload, along with their start and end times. These events can be retrieved via the communication<\/p>\n

interface for anomaly analysis.<\/p>\n

\u25a0Communication interfaces and protocol: Equipped with two fully isolated RS485 and infrared communication<\/p>\n

interfaces, featuring lightning protection and overvoltage resistance, compliant with the DL\/T645-2007 standard protocol<\/p>\n

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

This device employs an advanced dedicated integrated circuit design for electricity meters, integrating multiple<\/p>\n

functions into a single system. It enables remote multifunctional metering, multi-parameter monitoring, data<\/p>\n

freezing, and event logging. The system features overload alarms, automatic power disconnection alerts for phase<\/p>\n

loss, and phase loss detection records. Equipped with dual RS485 interfaces and a built-in high-power magnetic<\/p>\n

latching relay, it supports remote meter reading and billing, energy usage data analysis, and secure power management.<\/p>","protected":false},"featured_media":2883,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[34],"product_tag":[],"class_list":{"0":"post-2886","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\/2886","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=2886"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/media\/2883"}],"wp:attachment":[{"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/media?parent=2886"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product_brand?post=2886"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product_cat?post=2886"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/jrhmeter.com\/ru\/wp-json\/wp\/v2\/product_tag?post=2886"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
