Installation of a standard 35 mm DIN guide rail.
This meter is suitable for measuring the effective three-phase AC electrical energy with a nominal frequency of 50 Hz, for fixed indoor installation.
Apply at an ambient temperature of -25℃ ~ +55℃, relative humidity not exceeding 95%, and in an environment free of corrosive gases. Avoid exposure to dust, mold, salt mist, condensation, insects, etc.
It features good anti-electromagnetic interference, low power consumption, high accuracy, high overload capacity, high stability, anti-theft protection, and a long service life.

Installation and Use:
1.Installing the energy meter requires a qualified electrician or experienced professional who is committed to reading the manual.
2.The energy meter must be installed in a well-ventilated, dry indoor location. Use a standard DIN 35 mm mounting bracket. The bottom plate of the electricity meter must be securely fixed to a heat-resistant wall that is resistant to vibration.
3.Electricity meters must be installed in protective cabinets in locations where dirt and potential damage may occur.
4.Install according to the wiring diagram. It is best to use multi-strand copper wire to prevent the electricity meter from malfunctioning or burning out.
5.When the electricity meter is correctly connected to the power grid, the power indicator light on the meter will illuminate.
6.The electric energy meter should take thunder protection measures when used in an area where there is more thunder, so as to avoid damage to the electric energy meter by thunder.
7. The load capacity of the energy meter is between 0.05 Ib ~ Imax (direct access) or 0.02 Ib ~ Imax (via transformer access type). Exceeding this load capacity will result in meter or current coil inaccuracy. burn.
8.When the energy meter is used in the transformer, it is the actual power consumption that should be multiplied by the ratio of the transformer after reading the power indicator
9. Data display: 6 digital displays
10.Power instructions: A,B,C three LEDs indicate that the three-phase power supply is normal when the light is on.When a phase voltage is missing, the corresponding pressure indicator is off.
11. PULSE Indicator: When the PULSE indicator is on, a power pulse is detected.(When a sample signal is detected, the PULSE indicator lights up for approximately 80 ms).
12. Reverse Phase Power Supply Instruction: Rev.Indicates that the light is on in the direction of energy consumption.
Schematic and Wiring Diagram:
Measurement Method:
The energy meter is equipped with a photoelectric coupling power pulse test output port and is located in a wiring terminal box.Connect the +5VDC test equipment to terminal 17 (positive terminal) and the signal line to terminal 18 (negative terminal).
Package includes:
1 x Energy Meter
