Application

DTSY450/DSSY450-D series three-phase electronic prepaid energy meter made by SMT technology as our new type, adopted the imported large scaled integrated circuit, 16 bits A/D converter, digital multiplier, digital sampling and processing technology, and advanced chipset to perform data acquisition, processing and saving, it is suitable for measuring the active energy of AC50Hz or 60Hz, three-phase three-wire, or three-phase four-wire system. The meter complies with the technical requirements of standard of GB/T17215.321-2008《Class 1.0 and 2.0 static AC active energy meters》and GB/T18460.1-2001 《IC card prepaid energy selling system Part 3: Prepaid energy meters》.

Main features: administrated y computer, first purchase electric energy, then consume the electricity, within rated current it can limit the maxi operating power (controlled by power supply department).

This meter fixed indoor, operating in the ambient conditions as ambient temperature -20~+55℃, relative humidity not exceeding 85%, in the air there shall have no corrosive gas, and dust, mildew and insects shall be prevented.

Main functions and features

1. Measure active electric energy, needn't to be corrected after working a long time.

2. Purchase electricity first, then use electricity;

3. Alarm for lack of residual electricity.

4. Record information of power utilization.

5. One card for one user, anti-electricity theft .

6. Display residual electricity, accumulate and alarm electricity;

7. Can read user power utilization information backward.

8. Test pulse of electric energy output .
