Application

DDS833 electronic 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. 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 is use for setting indoor or
out door, and it can display total energy consumption by step and motor type impulse register. It has following
features: good reliability, small volume, light weight , specious nice appearance, convenient installation, etc.

Functions and features

Front board three fixed installation.
Standard configuration 5+1 digits display (99999.1kWh) by step motor and pulse machinery counter.
Standard configuration one port of pulse output passive (polarity), May select increase a distant port of pulse
output passive ( no polarity). And contact with all kind of AMR system conveniently, complying with standard
Standard configuration only one LED instructions signal of power impulse (red), may select add instructions
power state (green)and automatically detect the direction of the trend of load current and instructions by LED
(when display yellow, that is meaning the current is reverse). Please specified when ordering.
Single direction single component 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.
Direct connect and use, there are two types you may select. Standard configuration type 1B connection, may
select type 1A connection.
Standard configuration extended terminals cover, may select short terminals cover, in order to protect to use
electricity safely.
