summary:

DDSU5881 rail type energy meter is a new type of single-phase electronic energy metering product developed by our company. This product complies with the technical requirements for Class 1 and Class 2 static AC active energy meters in GB/T17215.321-2008 and IEC62053-21 international standards, and is suitable for measuring single-phase AC active energy with a reference voltage of 220/230V and a frequency of 50Hz/60Hz. This product is suitable for a wide voltage range, high reliability, long lifespan, high accuracy, low power consumption, and has functions such as anti-theft. It adopts a guide rail structure design, which is small in size and easy to install. The standard 35mm guide rail installation interface is internationally recognized. It can be widely used for single-phase energy metering and centralized installation in urban, rural, or factory enterprises.

Functional features:

1. Measurement function: It has the ability to measure positive and negative active energy, accumulate it in the total electricity, and measure it in both directions to prevent theftElectrical function.

2. Using a high-quality meter to display the accumulated power (6+1 digits), the display is clear, bright, and has good direct reading performance.

3. Electric energy metering pulse LED indicator (red).

4. Has power indicator function (green).

5. Adopting a passive pulse output interface with optoelectronic isolation, it facilitates meter calibration and pulse data acquisition.

6. Using high-quality and long-life electronic devices, with wide load capacity, strong overload capability, high precision, and low power consumption,The error curve is straight and does not require calibration for long-term operation.

7. Good anti creep logic design, when a reference voltage of 115% is applied to the voltage circuit, there is no current circuitWhen the current is flowing, the energy meter has no pulse output.
