Wide Application Scenarios
1. DC EV Charging Stations
Designed for high-voltage DC charging piles, the meter supports DC 0~1000V input with accurate bidirectional energy recording. Built-in data freezing function stores time-of-use energy data for traceable charging settlement. Compact DIN-rail structure fits directly inside charger control cabinets to save installation space.
2. Energy Storage Systems
It records charge and discharge energy separately to calculate battery round-trip efficiency. With RS485 Modbus communication, it seamlessly connects to EMS energy management platforms to optimize battery operation and maximize revenue.
3. PV & PV Hydrogen Production Plants
It measures DC voltage, current and real-time power on the DC side of PV arrays and electrolyzers, recording power peak & valley values to analyze power generation efficiency and hydrogen production power consumption for carbon accounting and production optimization.
4. Lithium Battery Production & VFD Systems
Compatible with shunt (0-75mV) and Hall sensor (0-5V/4-20mA) current input, it supports DI digital input and relay alarm output to trigger alerts for overvoltage, overload and reverse current, monitoring energy consumption and protecting production equipment.
5. Telecom Base Stations & HVDC Data Centers
Industrial wide temperature range (-30℃ ~ 70℃) enables stable long-term operation. Backlit LCD screen supports on-site data reading without cloud access for easy routine inspection.
Core Advantages & UL Compliance
1. UL Safety Certification for Global Export
Full UL certification together with CE, CPA and RoHS certificates are available. Complete test reports support customs clearance and project acceptance in the US, Canada, Mexico and other North American regions without extra re-testing.
-
2. High Precision Bidirectional DC MeasurementClass 0.5S / Class 1 accuracy for voltage, current, power and forward/reverse active energy. Optional dual DC input channels monitor two independent DC circuits simultaneously. Multiple current sampling modes fit high-power DC equipment.
-
3. Intelligent Communication & Data StorageStandard RS485 port supports Modbus-RTU and DL/T645 protocols for remote meter reading and parameter configuration. Built-in energy freezing, peak value logging and event storage retain daily/monthly energy data for energy audit and traceability.
-
4. Expandable I/O for Automation SwitchgearOptional 2-channel relay alarm output and 2-channel digital input detect DC circuit faults and link cabinet alarm systems. Local buttons allow quick setting of ratio, alarm thresholds and communication parameters to accelerate on-site commissioning.
