Application

Model DDS833B single 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 completely its independent intellectual property
rights and minimum size, and also a new single phase two wire active energy meter. 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 accurately and
directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net., it can display
total energy consumption by step type impulse register. it has following features: Good reliability, small volume,
light weight , specious nice appearance, convenient installation, etc.

Functions and features

35mm standard DIN rail installation, complying with standard DIN EN50022.
Single pole width (Modulus 17.5mm), complying with standard DIN43880.
Standard configuration 6+1 digits display (999999.1kWh) by step and machinery counter. May select 5+1
digits display (99999.1kWh).
Standard configuration Impulse output with no power (polarity), May select distant impulse output with no
power ( no polarity). And contact with all kind of AMR system conveniently, complying with standard IEC
62053-31 and DIN 43864.
Bicolor LED instructions power state (green) and signal of power impulse (red).
Automatic Detection the direction of the trend of load current. And Instructions (Only red power impulse
signal when working, If no green power, that is meaning the load current reverse).
Single direction measure single phase two wire active Power consumption. It is nothing with direction of the
trend of load current. Complying with standard IEC 62053-21.
Directly connect and use, there are two type you may select. Standard configuration type S connection, may
select type U connection.
Extended terminals cover, in order to protect to use electricity safely.
