Project Description
I. General Introduction
DDSY1598 STS Split Single Phase Din Rail Prepaid Meter takes digital medium as information exchange media. It is an active electric energy meter in which users load in pre-purchased energy and it takes energy as its billing to realize the functions of active power measuring and pre-payment control. MCU and CIU communicate via PLC. MCU includes measurement unit, real-time clock unit, load switch and other auxiliary equipments, while CIU includes numeric keypad interface and display.
II. Technical Features
i. Overload limit
ii. Bypass function
iii.Reverse current detection
iv.Terminal cover opening detection
v. Switching between operating mode and non-operating mode
vi.Switching between pre-payment and post-payment mode.
