DD862 Single-phase Active Watt-hour Meter



  • General
    The DD862 type single-phase watt-hour meter is a kind of induction type
    meter ,which is applicable to measure the rated frequency 50Hz and power loss in
    electrified-wire netting. The meter has novel design, rational structure and features
    of high overload, low power loss and long life etc.

    Function and features
    1. Sub-closed iron core
    2. The die-casting frame is made of alloy aluminum, to assure the magnetic line
    stably and reliably.
    3. Meter bearing has three kinds, may select dual jewel, magnetic thrust or magnetic
    float;
    4. May select 5+1 digits or 5 digits register;
    5. May select 5 kinds of cases: bakelite, PC, ABS plastic, glass and aluminum.
