DT(S)S238-7 ZN/SThree phase intelligent rail type electric energy meter (bidirectional)RS485)
main features
shouldThe electric energy meter is designed with an advanced microcontroller processing system, which has the advantages of simple circuit, high reliability, and high accuracy. The software, hardware, and structural design technology of this product are advanced, with high measurement accuracy. Combined with microcontroller resources, it achievesSolar and photovoltaic power generationuserBidirectional communication active energy metering,Three phase real-timeCurrent, voltagemeritoriousPowerReactive powerPower, power factorWaiting for over 20 electrical parametersMeasurement, with RS-485 communication function, good anti-interference and anti attack performance, wide working temperature range, and long-term stable and reliable operation. The various error performance indicators of this product comply with the technical requirements of national standards such as GB/T 17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and DL/T 645-2007 "Communication Protocol for Multi functional Energy Meters" (MODBUS communication protocol can be customized).
This electric energy meter adopts modular design and has a small volume、Easy to install、Easy networking and other advantages make it easy to implement terminal distribution energy metering. This product can be directly connected to the air switch、Circuit breaker、Install the contactor together as a factory、school、hospital、Signal acquisition units with power phase separation management requirements, such as shopping malls.
major function
·LCD digital displaydisplay
·forward and reverseBidirectional measurementThe forward power consumption is a 6-digit integer with 2 decimal places (9999999.99), and the reverse power consumption is a 5-digit integer with 2 decimal places (-999999.99)
·Supports backlit display, can be awakened by pressing a button
·Power outage display shows battery level, battery powered(Specially customizable)
·Reverse measurement, LCD displays reverse symbol
·Phase loss indication, LCD displays phase loss symbol
·three-phaseReal time current, voltage, power, power factor, frequencyMeasurement display
·Programming and meter reading operations can be completed through the RS-485 communication interface, and RS485 can work normally at 80% -115% of the rated voltage of the meter.
·RS485 bus terminals: 256, communication baud rate: 1200bps~4800bps (default 4800bps)
·2-channel power pulse output, corresponding to active powerReactive electrical energy,Passive pulse output,Compliant with DIN43864 standard
·After power failure, all stored data will not be lost and can maintain 15Years and above
·Zeroable battery level (displayed independently of the total battery level), reset to zero through a button (can be specially customized)
·The width of the electric meter is only 125mm, installed on a 35mm standard rail, and has a similar appearance to a 7P circuit breaker
