| Application | Model DT862 three phase four wire electromechanical multi-rate front board installed active energy meter is a kind of new style three phase four wire active energy meter, it is designed on the basis of original DEM082 meter, which gathers functions of multi-rate (time-sharing billing) electric energy measuring and max demand electric measuring. The meter completely accord with relevant technical requirements of class 2 three phase active energy meter stipulated in international standard IEC 62053-11. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four
wire AC electricity net, it is use for setting indoor or out door meter box. | | | | | Functions and features | ● Front board three fixed installation, the bottom of the meter and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. The cover is also made of bakelite material and has a transparent glass window. It has following features: good weather ability, high rigid, good insulation performance, etc.
● It has four tariffs, 6 time area, 12 date time.
● Infrared remote-control programmable, password recognition.
● It can keep the data forever when the power cut off, there is maintenance-free reserve battery in it.
● Function of max demand electric measuring
● May select port of RS485 and output pulse passive, it is useful copying meter conveniently.
● Standard configuration bottom bearing is used of double gem bearing, oriented bearing is made of high wear resistance copper alloy bush and stainless steel needle. It has following features: long life and minimal friction, etc. May select magnetic thrust bearing (Product Configuration code is QD).
● Standard configuration 6 digits display by drum wheel mechanical register, may select 5 digits display by drum wheel mechanical register (Product Configuration code is QV).
● Standard configuration without the device which can prevent retrograde, may select add the function of prevent retrograde. (Please specified when ordering).
● Three component measure three phase four wire active energy consumption. Complying with standard IEC 62053-11.
● Standard configuration direct connect operation, type 16B wiring, may select use CT for operation, type 48B wiring (Product Configuration code is QQ) and PT & CT for operation, type 48B wiring (Product Configuration code is QR).
● Extension terminals cover, in order to protect to use safety. | | | | | Technical parameters | Model | Accuracy | Reference
