Dts5558 Three Phase Electronic DIN-Rail Active Energy Meter 3 Phase 4 Wire Kwh MeterDTS5558 Three phase electronic din-rail active energy meter (125mm width)Model DTS5558 three phase four wire electronic DIN rail active energy meter is a kind of newstyle three phase four wire active energy meter, it adopts micro-electronics technique, andimported large scale integrate circuit, use advanced technique of digital and SMT techniques,etc. The meter completely accords with relevant technical requirements of class 1 three phaseactive energy meter stipulated in international standard IEC 62053-21. It can accurately anddirectly measure 50Hz or 60Hz active energy consumption from three phase four wire ACelectricity net. It can display total energy consumption by step and motor type impulse register.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 by themselves.● Ten pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.● 6 digits display (999999kWh) by step and motor type impulse counter.● Standard configuration one port of pulse output .● Four LED instructions respectively power state and signal power impulse.● Automatic detect the direction of the trend of load current. And Instructions on individual LED.● Single direction three components measure three phase four wire active power consumption. It is nothing with direction of the trend of load current. Complying with standard IEC 62053-21.● May select two components measure three phase three wire active energy or two phase three wire active energy● Direct connect to use, type S connection (Inlet from bottom, outlet from top).● Short terminals cover, it is used to reduce mounting space, and make mounting conveniently.
