----- AMk-AM2k -400 V- ELECTRONIC METERS -------- M-981 189 --- Page Nº 3

AVAILABLE MODELS:

- Meter type AMk- ITF (code 7 71 042 ) :
3 phase active energy meter single tariff, input isolated by transformer
( ... 5 A a.c. ). Display by means of an electromecanic integrating meter in kW.h.
- Meter type AM2k- ITF (code 7 71 044 ) :
3 phase active energy meter double tariff, input isolated by transformer ( ... 5 A a.c. )
Display by means of two electromecanic integrating meters in kW.h. The energy will
be accumulated by one or the another meter according to the state of the "tariff
changing" input provided in the own meter.
Common features:
- All energy meters have one pulse outputs. This output permit a remote
transmission of the measurement of the kW.h consumed.
Pulses: open collector type : 100 ms of duration - 24 V d.c. / 30 mA.
Ratio : 1 pulse / 1 kW.h
- Current transformer ratio is user-selected by means of mini-dips in the rear side
of the energy meter. SEE PARAGRAPH 3.1.-
- All energy meters operate over two quadrants: consumed power.
