1. Brief Introduction
DTSY-T01 is a single phase din-rail meter two wire split type prepayment keypad meter approved by STS. It can access to any STS standard system.Built-in 100A relay which can trip when over load or balance run out.The Din Rail Meter consist of Measurement and Control Unit (MCU) and Customer Interface Unit (CIU). MCU achieve data exchange with CIU through non polarity twisted pair cable and meanwhile supply power to CIU, CIU need not external power.Furthermore , customer can check the information in home and realize remote or SMS recharge.
