Product Brief
Place of Origin: Zhejiang China (Mainland) Brand Name: OEM Model Number: DD862
Display Type: Analog Only Phase: Single Phase Measuring Energy Range: 5-20A 10-40A 20-80A 30-...
Accuracy Class: 2.0 Output Voltage: 220V Mechnical Meter: Single phase Mechnical Meter

The DD862 single phase meter is designed to meet the IEC62053-21,IEC62052-11.


  • Meter case
  • Two types of cases are available One is the insulating case of protective-class 2 and the other is the weather-proof case complying to IEC60529 and Ip54.
  • Terminal block
  • The terminal block is molded of Bakelite . The voltage test link can be located inside or out-side of the meter case. The maximum diameter of the terminal hole is 8.5mm.
  • Driving element
  • The driving element consists of a voltage element and a current element, both of which are fixed to the frame. The voltage element has a low load adjustment mechanism, and the current element has an inductive load adjustment mechanism.
  • Rotor
  • The rotor shaft is made of aluminum alloy with a small hole in the upper end for storing lubrication and for fitting a brass bearing The worm is turned of brass, and is acid-cleaned or nickel-plated. The worm and shaft can be detached.
  • Braking element
  • The magnet is made of AINiCo5 alloy and designed as U-shaped so that the effect of short-time over current upon the magnet is negligible. The full load error can be fine controlled by adjustment mechanism.
  • Frame
  • The frame is die-casted by high-quality Al alloy of stable property to avoid distortion. The application of static spray-painting on the surface prevents the frame from oxidation.
  • Upper bearing
  • The pin is made of high-quality abrasion-proof stainless steel and is embedded on the brass pin base.
  • Lower bearing
  • Both double jewel bearing and magnetic bearing are available.
  • Register
  • The DD862 meter with direct-reading cyclometer type register is available.
  • The register is self-located and is mounted on the frame by one screw. Fixing with two screws is also available but needs to be manually adjusted. There are two types of gears available: brass gears and self-lubricating plastic gears.
