详情

1. over view
DDSY*5 is an active energy-metering instrument, using digital media as the data exchange medium, user will load the pre-purchased kwh, with settlement in terms of kwh, this meter is equipped with digital keypad interface, which is used for active energy metering and prepayment controlling.

2. function
DDSY*5 code-style single-phase prepayment meter reverse electricity metering positive electricity can be accumulated to a function of power.
