EEDDS238-4 ZN Multi-function Din-rail Energy Meter with RS485 Communication 4P

EEDDS238-1 ZN Multi-function Din-rail Energy Meter with RS485 Communication

Generaal Description:

     The meter is designed to measure single phase two wire AC active energy with time of use (TOU) function (the power flow of sharp time, peak time, flat time and off-peak time) and variable parameter. All of its functions comply with the relative technical requirement for class 1 single phase watt hour meter in IEC62053-21 and its data communication rules obey the requirement of DL/T645 or MODBUS-RTU. It is a long life meter with the advantage of high stability , high over load capability , low power loss and small volume.

Main Specification:

Basic Features:

• LCD display, backup battery for LCD display at powre failure

• Bi-directional total active energy measurement ,TOU active energy measure, reverse active energy measure in the total active energy

• The meter also display real voltage , real current , real power , real power factor, real frequency, real time and date

• The meter has 14 programmable internal tables, of which can set up to 14 intervals as four tariff during 24 hours. The minimum units of each tariff interval can be set up as 1 mintue.
