Application

DTSD833/DSSD833 electronic three-phase multi-function watt-hour meter is a kind of new style three phase four
wire multifunctional energy meter. The meter completely accord with relevant technical requirements of class 1 three
phase active energy meter stipulated in international standard IEC 62053-21 and class 2 three phase reactive energy
meter in international standard IEC 62053-23. It can accurately and directly measure 50Hz or 60Hz active energy
consumption from three phase four wire AC electricity net, This meter has LCD monitors shows the active energy
power consumption, and there are far infrared and RS485 communication module in it, contact with all kind of AMR
system conveniently. It has following features: Good reliability, small volume, light weight, specious nice appearance,
convenient installation, etc.

Functions and features

Front board three fixed holes installation, the cover is made of PC material which is transparent and anti-UV molded
overall, the base of the meter is made of pc and the terminal block is made of quality bakelite material which is
moisture-resistant, fire-retardant, high temperature molded overall. It has following features: Good weatherability,
high rigid, good insulation performance, etc.
Have six tariffs, may select 12 daily period of times. You can set the date arbitrary which can automatically read the
meter every month. May select single tariff function in weekend. (Please specified when ordering).
There are a clock and Maintenance-free backup lithium batteries in it. Battery capacity detection and display all the
time. It can keep the electricity data for 12 months. The data can be kept forever after power cut off.
May select cycle display (default) or push the button itemized display, it can display 14 data at most. Can select the
data which displayed. The decimal median which displayed can choose set one or two.
There is a polarity port of pulse output passive closed and a no polarity port of pulse output passive distant (the
output rate is 10 or 100 imp/KWh, can select ). Complying with standard IEC 62053-31 and DIN 43864.
There are far infrared and a port of RS485 communication data. It is use for setting and reading the meter. Set and
operation have password protection, communication protelot complying with standard DL/T645-1997.
Ten LED instructions respectively power state, signal of power impulse, the direction of the trend of load current, the
state rates just now and the data communications state.
Detect active and reactive energy, active and reactive power, voltage, current and frequency, etc. of three phase four
wire forward and reverse. Complying with standard IEC 62053-21 and IEC 62053-23..
Standard configuration direct connect and use, we can also choose another type of connection, and use CT and PT &
CT for operation.
Standard configuration extended terminals cover, may select short terminals cover, in order to protect to use
electricity safely.
