Switching output is relay output, can achieve the remote-control and alarm output.

The switch input adapts the method of on-off signal input and powered by outer power supply.

It can be gotten by meter when there is a change of on or off via a switching input module. The

parameter of switching input can not only get and show the state of local switching information

but also achieve the communication via RS485, which called “remote information” function.

Note: (17-18) are active energy pulse, (60,61,62,69) are NTC temperature measurement port,

(15,16) are clock pulse, (19,20) are reactive energy pulse, (40,41) are switch output and multiplex

with (60,61), (24,25) are 2 path of communication, (30，39) are switch input and multiplex with

(62,69).

7 Function description

7.1 Measurement

The meter can measure all electrical parameters such as voltage, current, active power,

reactive power, apparent power, power factor, frequency, 31st harmonic and total harmonic. The

value format of voltage, current, frequency and power are listed as below.

Example: U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW

7.2 Calculating

The meter can calculate the current active energy, forward active energy, reversing active

energy, forward reactive energy and reversing reactive energy.

7.3 Timing

The meter has 2 time lists, and can be divided into 4 time zones per year. Each time list can

be divided into 8 time periods and 4 tariff (F1、F2、F3、F4). The main purpose of multi-tariff is

promote the energy efficiency and economic benefits.

7.4 Demand

There are some definitions on demand:

Demand

The average power in the demand cycle.

Maximum demand

The maximum value of demand in a period of time.

Slip time

A recurrence method to measure the demand from any time point

during a period shorter than the demand period. The demand

measured by this means is called sliding demand. The recurrence

time is sliding window time.

Demand cycle

The time period between two same average value of demand.

The default demand cycle is 15 minutes, slip time is 1 minute.

The meter can measure 4 kinds of maximum demand: forward active, reversing active,

inductance performance reactive, capacitance performance reactive maximum demand and the

occur time.

7.5 History data statistics

The meter can record last 48 months or last 90 days history energy in each tariff.

7.6 Switching input and output

The switch input adapts the method of on-off signal input and powered by outer power supply.

It can be gotten by meter when there is a change of on or off via a switching input module. The

parameter of switching input can not only get and show the state of local switching information

but also achieve the communication via RS485, which called “remote information” function.

7.7 Temperature measurement

The meter support three path of outlay NTC temperature measurement, the range of

temperature is -40℃~99℃.
