APPLICATION

EM181RP THREE PHASE FOUR WIRE ELECTROMECHANICAL MULTI-RATE FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application
Model EM181RP 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 EM082 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 cover is made of quality of aluminum which is after anti-oxidation treatment and has a transparent glass window molded overall, the bottom of the meter is made of quality steel which is after double-through antirust processing, and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: Good weather ability, specious appearance, 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 RD).
● Standard configuration 6 digits display by drum wheel mechanical counter, may select 5 digits display by drum wheel mechanical counter (Product Configuration code is RV).
● 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 RQ) and PT & CT for operation, type 48B wiring (Product Configuration code is RP).
● Extension terminals cover, in order to protect to use safety.
