1. General

 DDSY5558 Single phase Prepaid electricity meter complies with IEC 61036. The meter adopts micro-electronic technology, has high precision, low power consumption.Depends on adopting large-scale integration (LSI) and surface mounting technology (SMT) as well, by using famous international brand components, it has high reliability and long service life. The meter uses fire-resistant ABS, the structure of the meter is air-proofed, data operation by advanced single-chip processing system.

The meter will remind the user to purchase the electricity by alarm when the electricity remained is limited, and cut off the power supply automatically when the electricity use up. It’s also able to limit maximal consuming power, anti-tamper function is optional. Each meter match with one memory card, and the meter can exchange the data with card bi-directionally through the card read device. User won’t lose electricity even he lost the user card, because a renewed card is acceptable.
