DD100TEFR LED display three phase four wire electronic DIN-rail multi-tariff active energy meter,RS485 communication
The meter is used to measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net.
The features of small size & DIN-rail mounting make it suitable for installation in distribution boards and small standard enclosures.
The meter is widely used in the office buildings, shopping malls, residences, airports and metro,etc.
The meter has function of different tariff measure for different time period. The RS485 communication module in it makes it convenient to meter-reading.
♦ 35mm standard DIN rail installation,complying with standard DIN EN50022.Or front board installed (mounting holes center distance 63 mm), users can choose any one by themselves.
♦Seven poles width.
♦LED 5+2 digits display (99999.99kWh).
♦Standard configuration one port of pulse output passive (polarity),may select increase a distant port of pulse output passive
(nonpolarity),complying with standard IEC 62053-31 and DIN 43864.
♦LED indicates respectively power-supply,impulse,and communication,etc.
♦Automatically detect the direction of the trend of load current. If the LED “REV” lights that means the load current is reverse.
♦Single direction three components measure three phase four wire active energy consumption. It is nothing with direction of the flow of
load current,complying with standard IEC62053-21,IEC62052-11.
♦May select two components measure three phase three wire active energy or two phase three wire active energy.
♦Multi-tariff is available (optional TOU or step tariff).
♦RS485 output interface (optional) enable remote data transfer,remote -control reading and parameter setting.
♦Direct connect operation or through CT or PT & CT.
♦Standard configuration short terminal cover, which is helpful to reduce installation space and make it convenient to install. May select extended terminal cover.
