Directly to a precise measurement of racing to the energy metering, seven LCD display shows consumption, has good reliability, small volume, light weight, beautiful appearance, advanced technology, characteristics of 35 mmdin standard installation guide rail type: and with good resistance to , low electricity consumption, high precision, high overload, high stability, preventing electricity-stolen, . Feature - Color: As Shown. - Material: Plastic+Electronic Components. - Size: About 12x10x6.5cm. - Installation of the meter requires an experienced electrician or professional and be sure to read this manual. - The meter should be installed in a dry and ventilated place in the room, with 35mmDIN standard guide rail type installation. The bottom plate of the installed meter should be fixed on the wall which is firm, refractory and not easy to vibrate. - In places where there is and possible damage to the institution, the electricity meter should be installed in the protective cabinet. - When installing wiring, wiring shall be according to the wiring diagram on the button cover of the electricity meter or the corresponding wiring diagram in this manual. It is best to adapt to the introduction of multiple copper wires to avoid abnormal operation or burning of the electricity meter due to poor contact. - When the meter is correctly connected to the , the power indicator light of the meter should always be on. - When the watt-hour meter is used in the area with more , protection measures should be taken to avoid damage to the watt-hour meter caused by . - If the load capacity of the watt-hour meter is between 0.05ib ~1max (direct access type) or 0.02ib ~1max (access type via mutual inductor), exceeding this load capacity will lead to inaccurate metering of the watt-hour meter or burning of the current coil due to heat. - When the meter is used with the , the actual electricity consumption shall be multiplied by the multiplier after reading the indicator of the meter. Specifications - Reference voltage 3x230/400 (V) - Display mode LCD frequency 50 (Hz) - Maximum current 30 (A) - : 7 bit LCD display. - Power indicator: when the three LED indicators A, are on, it means that the three-phase power supply is normal; The corresponding voltage loss indicator when a phase voltage is out of phase. - indication: when the indicator light is on, it means that the detected (when there is a sampling , the indicator light is on for about 80ms). - Reverse phase power indication: . When the indicator light is on, it means that the in the direction. Package list: 1 x energry meter
