  1. General Description

     DTS238-4-M static three phase four wire energy meter for active energy adopt advanced large-scale integrated circuit IC and SMT manufacturing technology. They have following features: bi-directional or unidirectional energy measurement , wide voltage , anti-tamper , high accuracy and reliability , large overload , low self-consumption , small volume , light weight !The meter can also display three phase R.M.S current , voltage ,active power , reactive power ,power factory , frequency ,and interval active energy .

The meter should be installed in suitable environment with ambient temperature range between -25℃~+55℃,the relative humidity less than 75% and temperature limits between    and-40℃~+70℃,   .

 The meter is manufactured complying with international standard IEC62052-11 on “Electricity metering equipment (AC) General requirements tests and test conditions” and IEC62053-21 on “Static meters for active energy (classes 1 and 2)”.

2.2.2 Self-consumption

Current circuit is less than 1.5VA

Voltage circuit is less than 2W/10VA

 

2.2.3 Starting current

       Under the rated voltage , rated frequency and COSΦ=1 , the meter shall start and continue to register on application of 0.2% In (if CT is used) or 0.4% Ib .

2.2.4 Anti-creeping

       The meter has anti-creeping logical circuit. When 115%Un is connected to the meter and current circuit is cut , the meter shall not create more than one pulse in a stipulated time

2.2.5 Average-life

       The meter can be used for at least 10 years in normal operation specified in this manual

2.2.6 LCD: 6+1 (999999.9kWh)

 

3.Basic Features

3.1 Measuring positive & negative active energy with negative energy accumulated into positive energy .

3.2 With three LED to show the on/off state of the power on three phases.

3.3 Measuring active energy without calibration under long term operation

3.4 Internal connection of current and voltage

3.5 High reliability due to adopting high quality components

4.Working principles

       Three phase voltage and current are sampled from respective sampling circuit and transformed into suitable signal, which is carried into integrated circuit , then the meter output pulse signal in positive appropriation to measured power to drive step-motor counter or LCD counter to realize energy measurement. The meter has energy pulse output for testing with pulse width of 80+20ms

6.2 Installation

The meter can be installed on a 35 mm DIN rail

6.2.1 The meter can not installed and used until it is checked goods and sealed before delivery

6.2.2 The meter should be install in the water proof box indoor or outdoor . the meter’s box should be fixed on strong and flame-resistant wall with a recommended height of about 1.8 m , where there is no corrosive gas around .

 

6.2.3 The meter should be install fully in accordance with connection diagram on the terminal cover, it is better to use copper as the leading wire for connection. All screws should be tightened.
