Model
DEM031CM single phase electronic multi-rate DIN rail active energy
meter is a kind of single phase two wire two
tariffs (tariff
conversion is controlled by timer outside or similar equipment) active
energy watt-hour meter. The meter
completely accord
with relevant technical requirements of class 1 single phase active
energy meter stipulated in
National standard
IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active
energy consumption from
single phase AC
electricity net. This meter has seven digits LCD monitors shows various
consumption data and
information. 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 0106828.1, any other country patent
certificate are in assessing. |
