【General Introduction】
Adopting special large-scale integrated circuit and manufactured with advanced SMT, Three Phase Four(Three) Wire Multi-function Electronic meter can be used for measuring active and reactive electric power at different time segment. Large LCD displays energy consumed in big characters. The circuit design and component selection allow maximum tolerance thus the meter can run with stability, accuracy, high overload, low power consumption and reliability. The built-in storage unit can assure the security of data. The meter can be widely used in the field of electric energy measuring and power automatization.

 

【Functions and Characteristics】

* Three phase active(reactive) power consumption measurement at different time segment.
* Display: large LCD display.
* Record ,display and store the total active/reactive power consumption and multi rate power consumption during latest 3months.
* Measurement of maximum demand and billing.
* Two time zones, four rates, ten time periods.
* Event record of voltage/current missing, programming, demand clearance.
* Real time data: time, voltage and current.
* Self verifying and monitoring of power supply, power network, operation situation of meter.
* The function setting, programming and reading (concentrated reading possible) can be realized via infrared and RS-485 ports.
* DT(S)SD22A has the function of prepayment. Programming and reading through IC card. The meter has a relay, two level alarm. It can also record and display the energy consumed.
