Model No.: DDS155
This meter is designed to measure single phase two wire AC active energy and variable parameter. All of its functions comply with the relative technical requirement for class 1 single phase watt hour meter in IEC61036 and its data communication rules obey the requirement of DL/T645 or MODBUS-RTU. It is a long life meter with the advantage of high stability , high over load capability , low power loss and small volume .
1. LCD display
2. Bi-directional total active energy measurement ,reverse active energy measure in the total active energy
3. The meter also display real voltage , real current , real power , real power factor
4. Pulse LED indicates working of meter,Pulse output with optical coupling isolation
5. RS485 communication port
6. 35mm din rail installation
1.35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board setting
(mounting holes center distance 63 mm), users can choose any one by themselves.
2. Six pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
3. Standard configuration 6+1 digits display (999999.1kWh). May select 5+2 digits display (Please specified when ordering).
4. Two LED instructions respectively power supply state (green) and signal of energy impulse (red).
5. Standard configuration don't detection direction of the flow of load current. May select automatic detection the
Direction of the flow of load current. And instructions by an individual LED.
6. Single direction measure single phase two wire active energy consumption. It is nothing with direction of the
Flow of load current. Complying with standard IEC 62053-21.
7. Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect operation, we can also choose another type of connection, and use CT (Product Configuration code is IC) and PT & CT
