Features Characteristics & Standard Adopted
Model DD862a single-phase watt-hour meter is one of the AC induction meter used in measuring the single-phase alternating working power energy at 50 or 60Hz.
◆Double gems(working life =10 years) or magnetic-pushed
bearing unit(working life =15 years).
◆ The number can be clearly read as the 6-digit big font wheel was mounted.
◆ It has steady mechanism structure by using the specially
treated aluminium alloy structure.
◆ Phenolic resin or steel plate are used as the material of base.
◆ Closing can be produced by different composition of normal
plastic or ABS fire-resistant plastic and transparency or
untransparency
