Energy Measurement Digital Energy Meter 3P4W Electric Meter with Power Off Display

1. INTRODUCTION:

Three-phase Active&Reactive Energy Meter adopts the advanced special energy measuring chips and the multi-rate technology, using the date sampling and SMT technology. The product is designed and produced according to the practical situation of the dweller. All the elements inside the meter have the feature of long-life, high-reliance.

2. FUNCTION:

• Measure Phase-A, B, C, total active power, total reactive power and total apparent power accurately;
• Measure the current and voltage of Phase A, B and C;
• Measure the average power of total active, total reactive and total apparent power respectively;
• Measure the total power factor and Phase A frequency;
• Controlled by Imported chip microcomputer and full-digitalized metering to realize anti-theft.
• Indicate overload current, overload voltage, the meter will be flashing when the voltage is over 380V or the current is over 1.25Imax;
• Three phase can supply power at the same time, the meter can work only one phase has power; also has the function of phase loss indicator;
• Have the function of remote digital impulsing output, configured with corresponding automatic meter reading system, monitor the working performance of meter in real-time.
• Power off memory function to ensure data last for 10 years;
• Consumption history recordable,and energy freeze function ;
• Communication Port: RS485 Or In-fared.
• Display Method: Backlit LED

3. TECHNICAL PARAMETERS:

4. TRANSPORTATION AND STORAGE:

• The meters should be free from violent collision when being delivered or sealed off, and the buyer should in accord with the rules of ZBW003-82/84 for General Technical Conditions Of Instrument And Apparatus Packaging to transport and store them.
• The meter should be stored in its original pack and the ambient temperature to keep them should be within -25℃ and 70℃, there are no corrosive gas in the air.
• The meter should be placed on the shelves in the warehouse and the stack height should be less than 5 cartons.

5. INSTALLATION AND CONNECTION:

1. The meter shall be installed in the dry area with good ventilation condition to ensure safety and reliability during installation and operation. If the meter shall be installed in the area with dirty and easily gets damaged, the metering box should be configured to protect meter against the dirty environments.

2. The dimension of meter is as below: the holes should be digged ahead accord with the size and the meter bottom should be fixed on the strong, fire-proof subjects.
