Product Description Low voltage feeder monitoring device - communication unit1.Product profileThe low-voltage feeder monitoring device consists of a communication unit, a power module, and a monitoring unit. The communication unit is generally installed in the distribution cabinet, column mounted JP cabinet, or low-voltage cable branch box. It serves as a data aggregation gateway to achieve upstream communication through carrier modules, communicate with downstream monitoring units through CAN bus, and achieve local maintenance of the system through Bluetooth interface. The number of monitoring units that can be connected is not less than 64; The power module provides DC power, CAN bus, and sampling voltage to the monitoring unit through a cascaded interface. A single power module can be connected to no less than 10 monitoring units; The monitoring unit is connected to an external current transformer to achieve current detection function, connected to the voltage sampling signal output by the power module to achieve voltage detection function, connected to a switch input to achieve station status monitoring, with functions such as topology characteristic signal transmission, characteristic signal analysis, and phase sequence recognition.2.Product specificationsperformance parametersperformance indicatorsOperating power supplyRated voltageAC 220V (allowable deviation -30%~+40%).Power consumptionStatic power consumption: ≤2VA, active power ≤1.5WDynamic power consumption: ≤4VA, active power ≤3Wenvironmental conditionsambient temperature, humidityTemperature range: -40~+70°CMaximum rate of temperature change: 1.0°C/minRelative humidity: 10 to 100%Maximum absolute humidity: 35g/m3the environment in which it is usedThere is no danger of explosion, no corrosive gases or conductive dust, no presence of severe mold, and no source of severe vibration or shock.storage temperature -40oC~80oCClockDaily errorThe internal clock accuracy shall be better than 0.5s/d, theAccuracyMaintenanceparameter reading, remote upgradingEquipped with the function of parameter reading and modification through Bluetooth and RS485 communication interface.with the ability to upgrade itself and its access equipment locally and remotelyIt has the functions of adding and deleting access devices, as well as querying and modifying access device parameters.ResetHardwarePress and hold (>3s) the reset button for hardware reset, theSoftwaresoftware remote reset3.Selection specificationsfunction moduleSerial numberfunction pointfunction point descriptionscommunication moduleTelemetry1Incoming and outgoingWith 4-way open-in telemetry status√communication interface2CAN communicationStandard configuration of 1 road for the lower cascade multiple power modules, transmission downlink monitoring unit support through the CAN interface to achieve online upgrade program√3debugging interfaceSupport 1 RS485 interface for product debugging√4Bluetooth interfaceSupporting the maintenance of communication units and monitoring units through the Bluetooth interface√5HPLC interfaceSupporting the maintenance of communication units and monitoring units through the carrier interface√Output6DC OutputProvide DC12V±0.5V power output interface externally, with load capacity not less than 300mA√Note: "√" indicates that this function is standard, "○" indicates that this function is optional 4.Product installation and schematic diagram5.About our service * We could provide 7* 24-hour phone call after-sales service. * We provide a 2-year guarantee time and will change the meter for you within 1 year if there's something wrong with the product.
