Functions And Features

Relative name:Mechanical Meter | Electromechanical Active Energy Meter

Functions and features for LEM501 Series

● Front panel mounted in 3 points for fixing, the appearance and dimensions are in accordance with Standards BS 7856 and DIN 43857.

● The meter cover and terminal cover are made from the dampproof, fire-retardant, thermostability and good Bakelite pressed in a whole-module. The meter bottom and terminal block can be also made from same high quality Bakelite with the features of good weather resistance, high rigidity and excellent insulation, etc. The meter has a transparent glass window.

● The meter cover and terminal cover can be made from the transparent anti-ultraviolet PC pressed in a whole-module. The meter bottom and terminal block can be made from the dampproof, fire-retardant, thermostability and good Bakelite, with the features of good weather resistance, high rigidity and excellent insulation, etc.

● The frame is made of aluminium alloy pressed in an overall module, with the features of stable magnetic circuit for long-term use and anti-impact, etc.

● Both voltage components and current components adopt dual insulation structures, with good electrical characteristics.

● All of the error adjustment adopts the stepless speed change mechanism. The meter starting and creeping are finished by the anti-creeping pin on plate rotation shaft, convenient for the user calibration.

● The bottom bearing is magnetic suspension type. The top guiding bearing is made of the specialized high abrasion resistance copper alloy bushing and stainless steel pin, with long life use and small frictional resistance.

● You can select 5 digits or 6 digits or 7digits drum-type mechanical register.

● Standard configuration is: no anti-reverse device. You can add the anti-reverse device when ordering.

● Standard configuration is: no handle. You can add a handle easy to carry when ordering.

● Terminal cover is extended type, to ensure the tamper-proof function.
