Application
Model DRM1250SF-7P three phase electronic DIN rail active energy meter is a kind of new style single
Phase two wire active energy meter, it adopt micro-electronics technique, and imported large scale
Integrate circuit, use advanced technique of digital and SMT techniques, etc. It has its completely
Independent intellectual property rights and minimum size. It has already passed the test of the
International authority KEMA. 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. 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 0156631.9, any other country patent
Certificate are in assessing.
Functions and features
1.35mm standard DIN rail installation, complying with standard DIN EN50022.
2. Pole 1.5 width (Modulus 17.5mm), complying with standard DIN43880.
3. Standard configuration 5+1 digits display (999999.1kWh) by step motor type impulse register,
May select 5+1 digits display (99999.1kWh).
4. Standard configuration pulse output passive (polarity), May select distant pulse output passive
(nonpolarity). And contact with all kind of AMR system conveniently, Complying with standard
IEC 62053-31 and DIN 43864.
5. Two LED instructions power supply state (green) and signal of energy impulse (red).
6. Automatic detection the direction of the flow of load current, And Instructions (Only red energy
Impulse signal when working, that is meaning the direction of the flow of load current reverse).
7. Single direction measurement single phase two wire active energy consumption. It is nothing
With direction of the flow of load current. Complying with standard IEC 62053-21.
8. Directly connect operation, there are two types wiring you may select, Standard configuration
Type S wiring. May select type U wiring (Product Configuration code is UM).
9. Extension terminals cover, in order to protect to use safety.
