PS-7 Single Phase Multi-function Watt-Hour Meter

The single phase multi-function watt-hourmeter, a type of fully electronic active energy electricitymeter,conformsto IEC 61036 and IEC 61038. The meter features its innovative structure designand reliable electric capabilities, so it is an ideal option for measuringhousehold electric energy with time-of-use (TOU) as well as balancingelectricity load better.

MainCharacteristics of Single Phase Multi-function Watt-Hour Meter
(1) Active energymeasuring
It can measure total energy and energy of every tariff. The reverse energy ismeasured and added to the corresponding forward energy. The energy measuringrange is from 0 to 99999.999kWh.
(2) RTC
an external real time clock realizes the timing and TOU, including calendarprogrammed and day light saving time setting.
(3) TOU control
it can offer 4set schedules to realize multi-TOU control. The day can bemaximally divided into 10 periods with 4tariffs for each schedule. Work-offdays can be also programmed in a week.
(4) Energy Record
it can store energy in billing day of each month. The billing day can be setwithin 1 to 28 of one month. It may store history energy data for 12 months.All data may be accessed via personal computer (PC) or hand hold unit (HHU).
(5) Display
it can display by LCD indicator during both power supply and power failure. Itsupports automatically cyclic display mode and button pushing display mode.Display items can be set by user via PC or HHU. If power failure lasts 7 dayscontinuously, display will be turned off and can be awaked by infraredcontroller or pushing button.
(6) Event Log
It can record last five times of case opening during normal operation and onceof such event in case of power failure. The other events will be recordedincluding power down, programmed setting and current reversing. The totalhappening times of each event plus their respective latest five stating timesand ending times can all be accessed via PC or hand hold unit (HHU)
(7) Communication
it can communicate via infrared interface, which realizes the meter reading andparameter setting. There is a separate battery inside the meter for meterreadings under power failure condition.
