DEM011TA single phase electronic DIN rail active energy meter is a kind of new style single phase two wire active energy meter, it is fit for use on rental houses, and with two power energy counters, use for recording total energy and daily energy. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. It can accurate and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it can display total energy consumption by step motor type impulse register. This meter has LCD display active energy, it has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc. This meter has already got the patent certificate from China State Intellectual Property Office at present. Patent certificate NO. ZL 2006 3 0106726.X, any other country patent certificate are in assessing. |

| Functions and features |
¡ñ 35mm standard DIN rail installation, complying with standard DIN EN50022. Or front board setting (mounting holes center distance 67 mm), users can choose any one by themselves.
¡ñ Six pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
¡ñ Two 6 digits LCD display, use for display total energy (5+1 digits display) and daily energy (4+2 digits display), and we can cleared the number form the red button on the panel, the red button can be protected by lead closed.
¡ñ Standard configuration LCD display without backlighting, may select with white backlighting, and there is maintenance-free battery, use for display when the power cut off. (Product Configuration code is TC)
¡ñ Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse output passive (nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard IEC 62053-31 and DIN 43864.
¡ñ Two LED instructions power supply state (green) and signal of energy impulse (red).
¡ñ 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 (Only green LED energy pulse signal when working, that is meaning the direction of the flow of load current reverse).
¡ñ 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.
¡ñ Directly connect operation, there are two types wiring you may select. Standard configuration type T wiring, may select type S wiring (Product Configuration code is ZA).
¡ñ Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is TB). |
