Model: SD-AW96KW SD-AW80KW SD-AW72KW SD-AW48KW Pointer mono-phase active power meter
Model: SD-BW96KW SD-BW80KW SD-BW72KW SD-BW48KW Pointer three-phase three-wire unbalanced load active power meter
Model: SD-CW96KW SD-CW80KW SD-CW72KW SD-CW48KW Pointer three-phase three-wire balanced load active power meter
Model: SD-DW96KW SD-DW80KW SD-DW72KW SD-DW48KW Pointer three-phase four-wire unbalanced load active power meter
Model: SD-EW96KW SD-EW80KW SD-EW72KW SD-EW48KW Pointer three-phase four-wire balanced load active power meter
Accuracy class: 1.5. For SD-W48, the accuracy class is 2.5.
Power specification: 100W 200W 300W 500W 600W 1KW 3KW 5KW 10KW 15KW 20KW 30KW 50KW 60KW 75KW 80KW 100KW 120…5MW. The meter should be used with a current transformer of which primary current is higher than 15A and external secondary current 1A or 5A.
Voltage specification: The meters are used for low voltage such as 100V 110V 220V 380V 415V 440V. For medium voltage such as 1KV-35KV, they should be used with a voltage transformer of which external secondary voltage is 100V.
Product performance: All the meters are equipped with pure white silk-screen printing dial scale. The movement is the one universally used in magneto-electrical meters. The case is made of oridinary ABS plastics or flame retardant ABS plastics, of which the resistant temperature can be up to 85℃. The base is made of PC plastics or flame retardant PC plastics, of which the resistant temperature can be up to 120℃. The resistant voltage is higher than 2000V. This kind of meter is easy to install which high-strengthen plastic grip piece by screwing down the nut so that the meter is of high immobility.
Measurement fearures: Each pointer power meter consists of a magneto-electrical meter and related power converters, mainly used for meter of active power measurement in single three-phase AC transmission circuit. The advantages are simple strusture, convenient measurement, as well as insensibility to temperature and external magnetic field. When power signals are converted into DC signals by the converters, the following measurement priciples are the same as that of magneto-electrical meters.
