DDS661A Static Single electricity meters

Detailed Product Description

 

DDS661A static single electricity meters

Functions and features:

1. Measurement for active electric energy, and no calibration is required during long-term working.

2. The USA-based ADI company-made updated professional measuring chip ADE7755(ADE7757) adopted, it has a wide dynamic working range with manganin divert serving as current sensor, consequently, the actual overloading capability is up to over 10 times than it is rated.

3. Anti-creeping logic circuit installed, any creeping is unavailable, in additions, this meter is equipped with special devices for avoiding tampering the data of consumption.

4.Low starting-up current (low current available cab can be accurately measured when electric appliances are standing by or a cell phone is being charged), this meter has best error linearity.

5. SMT superficial wainscot technology provided, the whole production process is anti-static electricity.

6. This meter is small in size, light in weight and low in power loss.
