Introduction:

The DTS1000 three-phase four wire rail type NB electric meter adopts high-resolution segmented LCD display. It can set parameters such as clocks and speed periods, and can be directly deployed on GSM networks, UMTS networks, or LTE networks through the new generation Narrowband Internet of Things (NB IoT) communication interface to reduce deployment costs and achieve smooth upgrades. User management personnel use NB IoT wireless communication protocol to make data transmission more direct and efficient.

Technical parameters of three-phase four wire rail type NB electric meter:

【 1.1 】 Wiring system: three-phase three wire/three-phase four wire;

[1.2] Accuracy level: Active power: 0.2S level; Reactive power: Level 2;

[1.3] Voltage specifications: Three phase three wire: 3 × 100V Three phase four wire: 3 × 57.7/100V;

[1.4] Current specification: Transformer connection type: 0.3 (1.2) A; 1（2）A； 1.5（6）A； 5（6）A；

Communication protocol: DL/T645-2007 protocol;

[1.6] Communication interface: NB-IOT（（Narrow Band Internet of Things，NB-IoT））， Optional RS485 interface and far-infrared communication interface.

The advantages of three-phase four wire rail type NB electric meter are introduced as follows:

【 2.1 】 Signal Stability: NB IoT communication transmission signals are stable and uninterrupted (supporting China Mobile, China Unicom, and China Telecom). It can be used wherever there is a signal!

【 2.2 】 Simple construction: The instrument is installed in a guide rail style, and the instrument data is directly transmitted to the platform (computer and mobile). No wiring is needed in the middle, making construction more time-saving!

【 2.3 】 Cost saving: The combination of electricity meter and gateway eliminates the need for a meter reader and RS485 cables, saving material and labor costs.

【 2.4 】 Efficient management: Adopting prepaid electricity sales method and time-based rates. It can detect data anomalies during the electricity consumption process, with the functions of freezing and settlement, making it difficult to cut off power and avoid electricity disputes!

Suggested installation environment:

1、 The three-phase four wire rail type NB meter should be installed in indoor or outdoor meter boxes. The base can also be installed and fixed on a sturdy and fire-resistant wall. It should not be installed in environments with corrosive gases in the air. The specific installation dimensions are shown in Appendix Figure 1. (Recommended installation height of 1.8m)

2、 If the machine is subjected to severe impact or significant damage to the casing due to falling from a high altitude during installation, please do not install or power it on, and contact the supplier as soon as possible.
