Three Phase AC Active Mechanical Kilowatt Hour Meter¹

Product Description ApplicationDT256/DSS256 Type Three phase Alternating Current Active Watthour Meters completely accords with relevant technical requirements of class 2 three phase active energy meter stipulated in International standard IEC 62053-11. It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire or Three Phase Three Wire AC electricity net, it is use for setting indoor or out door meter box.Function and features1. Front board three fixed installation, the cover is made of PC material which is transparent and anti-UV molded overall, the base of the meter is made of black glass fiber which can be fire-retardant and is enhanced PC material, the terminal block is made of exceuent quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: Good weatherability, anti-impact, specious appearance, etc.2. The meter frame is adopt aluminum molding with excellent mechanical strength, stable structure and anti-impact.3. Voltage components and current components are used of double insulation structure, switch has good electrical characteristics.4. Standard configuration the meter is adopt magnetic thrust bottom bearing, oriented bearing is made of lubrication graphite bush and stainless steel needle. It has following features: Small abrasion, long life and minimal friction, etc.5. You may select doule gem bearing (Product Configuration code is WP)6. All kinds of error adjustment mechanism adopt no step shifting mechanism. The meter starting and creeping needn't to be adjusted which is finished by anti-creeping hole of disc and convenient for adjusting by users.7.
