HB866-P1 postpaid, HB866-PL networking prepaid Intelligent multi-user energy meter

Product Introduction

This multi-user energy meter is a new product independently developed by our company. It can be controlled separately for 36 single-phase or 12 three-phase users (or mixed single-phase and three-phase on the same meter). It is a fully electronic intelligent multifunctional energy meter, with a single-chip microcontroller as the core and a fully modular structure. It can simultaneously measure the electricity consumption of multiple users and independently monitor the electricity consumption of each user, and cyclically display the cumulative electricity consumption of each user. It can achieve household detection, centralized installation, and centralized management, and fundamentally eliminate various theft and leakage phenomena, reducing many electricity disputes and accidents. This meter can measure positive active energy and cyclically display electricity consumption information for each household. It is easy to install and can be remotely read by a computer through RS485 networking, making it convenient for management departments to timely grasp and collect electricity consumption information for each month. The product complies with the GB/T17215.321-2008 standard for Class 1 and Class 2 Static AC Active Energy Meters. The product is widely used for electricity metering in enterprises and institutions, urban residential areas, student apartments, old building electricity meter renovation, high-rise buildings, etc.

This energy meter is centrally installed and has the advantages of small size, anti electromagnetic interference, low power consumption, long service life, and intelligent meter reading.

Features

• 1. Multi user energy meters can accurately measure high precision and measure active energy in both positive and negative directions, preventing electricity theft.

• 2. Display the electricity consumption of each household in a clear and intuitive loop.

• 3. The watch case is injection molded in one go, with good sealing and insulation properties. And special wiring terminals and double bolt crimping are used for safe and reliable use.

• 4. According to user needs, single-phase and three-phase can be combined for household use. Single phase can control up to 36 households, while three-phase can control up to 12 households. The wiring is simple and the operation is convenient.

• 5. The whole machine has low power consumption (<6VA) and significant energy-saving effect. Specialized anti creep and watchdog circuits make operation more reliable

• 6. Equipped with computer remote meter reading function. The communication circuit design is stable and can effectively avoid signal interference caused by lightning strikes and other factors.

• 7. Each circuit adopts independent measuring chips for precise and non interfering measurement, with excellent performance and remote market shared measuring chip solutions.

• 8. Adopting high-precision current transformers, it does not generate heat during operation, has good electrical isolation effect, strong overload capacity, and long service life.

Purpose and Scope of Application

Under normal use, the multi-user energy meter displays the user number and accumulated power in a cyclic LCD display; Or search through the button.

Meter reading method

1. Direct reading meter reading

The display window of this energy meter is LCD, and the upper row displays the user number: for example, "1 battery level" indicates the first household; '2 Electricity' represents the second household... The user number '1 Electricity' in the upper row corresponds to the electricity consumption of the first household in the lower row, and so on. The highest display shows 99999.99kWh, with one household switching every 6 seconds.

2. Computer networking remote automatic meter reading (user selected).

3. Prepaid for internet connection, pay first and then use electricity (user's choice).

Transportation and storage methods

1. The transportation and assembly of electric energy meters should not be subjected to severe impacts, and should be transported and stored in accordance with ZBY00382/84 "Technical Conditions for Instrument Packaging".

2. When not in use temporarily, do not damage the original packaging. Store in an environment with a temperature of -25 ℃ to+70 ℃ and a relative humidity of no more than 85%. Long term storage should be moisture-proof, shock resistant, and heat-resistant.

Safety Precautions

1. Please read the manual carefully and pay attention to the wiring method. Do not connect the household number and the live and neutral wires incorrectly to avoid damaging the electricity meter.

2. The electric energy meter must be installed in the distribution box and should not be installed in a leak proof manner to prevent rain and sun exposure.

3. The neutral wire of the electric meter only provides the electric meter circuit, and the distribution box should not be operated without a neutral wire. Additional user neutral wire and ground wire terminals should be installed inside the distribution box.

Special Reminder: After wiring the electricity meter, it should be carefully checked to avoid zero operation!
