Product Details
EM619002 dc energy meter with bidirectional measurement, designed for telecommunications base stations, DC charging piles, BESS, solar photovoltaic, data center, and other applications, this meter can measure the voltage, current, power and forward and reverse energy and so on in the DC system. In the actual use of the site, you can measure the total power, but also measure the energy within a specified period of time. The test results can be used for local display, but also with industrial control equipment, computers to form a measurement and control system.
The meter has an infrared communication interface and RS485 communication interface and supports Modbus-RTU protocol and DLT645 protocol at the same time. The meter has a relay alarm output and digital input function. It can set the ratio, alarm, and communication through the meter panel keys according to different requirements. The meter has event recording of the switch(Modbus protocol), programming and event setting records(645 protocol), instantaneous and timing freeze function of data(645 protocol), maximum and minimum value recording function of voltage and current power.
Main features and parameters of the product:
1. The maximum measuring current can reach 2000A
2. Measuring voltage DC 5V~1000V
3. Auxiliary power supply 9~60VDC
4. Metering method: two-way active power metering
5. External shunt (need to be purchased by the customer)
6. accuracy Cl1.0, IP51 Protection
7. RS485 communication, DLT645/modbus dual protocol compatible
8. With battery and rate (the battery can maintain RTC for about 5 years when the meter is powered off)
9. Widely used in photovoltaic power generation, energy storage battery systems, electric vehicle charging piles, communication base stations, computer rooms and other fields
Features
Rate: Four Tariffs with 8 Time Slots
Alarm function: over-voltage, over-current alarm, threshold can be set.
Event record: The device itself stores the last 20 records when overvoltage, undervoltage, and overcurrent occur
Display: LCD displays DC power, current, voltage, tariff power, data wheel display (time interval 5S), you can also turn pages by pressing an external button.
Backlight: Press the page turning button to light up the backlight, which is convenient for viewing data when the light is insufficient
Communication: Supports RS485 communication with protocol DTL645, which allows parameters setting and read or write power data
