DD949 Mechanical/ DDS949 Electronic Socket Meter
DD949(S) single-phase watt-hour meter (round socket) is used to measure electric power in single-phase 50Hz or 60Hz AC circuit. It should be fixed to use with the limited working temperature of -30~+55°C. The relative humidity should not exceed 95% and without the corrosive gas and salty spray in the air. Its mechanical socket meter has the same cassette mechanism as DD949 meter. Its electronic meter has the same cassette mechanism as DDS949. Its dimension is designed as per American standard.Structure1. Case: round bakelite base and round transparent glass cover2. Bearing: magnetic bearing or double-jewel bearing3. Register: wheel type, six digitals4. Frame: molded aluminum alloy5. Braking component: Al, Ni, Co double-pole magnet, has two types of dividing magnet including adjusting board type and adjusting screw type6. Driving component: unitary rivet type voltage steel core, revolving phase plate type phase adjustment, handle type and adjusting screw type light load adjustment7. It is designed as per the most advanced technique with reasonable construction, beautiful appearance, stable performance, low consumption, and high overload of 6.67 times loadTechnical parameter:Accuracy class: class 2 for mechanical meter class 1 or 2 for electronic meterReference voltage: 110V, 120V, 220V, 230V, 240VFrequency: 50Hz or 60HzBasic (max. rated) current: 15 (60) A, 10 (60) A, 150 (100) A, 20 (120) AVoltage circuit consumption: ≤1W, 6VACurrent circuit consumption: 2.5VABasic rotating speed: 9r/minTorque: 4.0x10-4 N.mWeight of meter: 1.5kg
