Description

DDS5558 Single phase electronic din-rail active energy meter (75mm width)
Model DDS5558 single phase electronic DIN rail active energy meter is a kind of new style
single phase two wire active energy meter, it adopts micro-electronics technique, and imported
large scale integrate circuit, use advanced technique of digital and SMT techniques, etc.
The meter completely accords with relevant technical requirements of class 1 single phase
active energy meter stipulated in international standard IEC 62053-21. It can accurately and
directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity
net, This meter has seven digits LCD monitors shows the active energy power consumption.
It has following features: Good reliability, small volume, light weight, nice appearance,
convenient installation, etc.
● 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.
● Six pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
● May select 6+1 digits display (999999.1kWh) or 5+2 digits display, it can be arbitrary set by users from far infrared or port of RS485 data communication.
● Standard configuration one port of pulse output passive.
● There are a port of far infrared data communication and a port of RS485 data communication. Standard configuration communication agreement complying with standard DL/T645-1997, can also choose any other communication agreement.
● Three LED instructions power state, signal of power impulse and communication state. 
● Standard configuration don\'t detect direction of the trend of load current. May select automatic detecting the direction of the trend of load current.And instructions by an individual LED.
● Single direction measure single phase two wire active power consumption. It is nothing with direction of the trend of load current. Complying with standard IEC 62053-21.
● Standard configuration connection (Inlet from bottom, outlet from top) for direct connect to use, we can also choose another type of connection, and use CT and PT & CT for operation.
