Einphasen-Charge-gesteuerte Smart Energy Meter

Product Overview: DDZY3699 single-phase charge-controlled smart energy meter (remote / switch built-in) is a new generation intelligent energy meter with carefully optimizing design. It adopts an international well-performed single-chip microprocessor and reliable peripheral circuits and absorbs domestic and foreign software advantages of similar products, with stable and reliable special electronic measurement circuits, IC card technology and advanced SMT technology. The product is simple in structure, reliable in performance, with anti-tamper, high accuracy, high overload, good linearity, low power consumption, small size and light weight. Main Features: Measurement function: Measure positive active energy, negative active energy and time-interval energy; can store at least 12 months total energy and energy of each tariff; Charge-controlled function: Energy meter inside itself can calculate real-time credit, when setting meter parameters, pre-storing electricity charge, writing back information and distributing remote control commands to operate, all requires safety certification through the ESAM; Measuring and monitoring: to measure, record, display the current energy meter voltage, current (including neutral line current), power, power factor and other operating parameters; Event log: Permanently record the clearance event and accurately record events of programming, time adjustment, the power-failure, switch-on and switch-off as well as meter cover opening event; Rates, Time-interval and price options: two time zones can be set in a whole year; can freely program 8 time intervals within 24 hours, with two sets of tariff time intervals and two sets of price options, each set of time intervals supports 4 a rate; Display: LCD monitor, high-contrast, wide angle, life expectancy over 10 years under normal condition; Alarm function: When the meter has faults, the LCD monitor displays an error message; Freezing function: Can realize timing freeze, instant freeze, agreed to freeze, day freezing and freezing on the hour; the corresponding data identifications accord with DL / T 645-2007 and recorded documents requirements; Timing function: built-in hardware clock circuit with temperature compensation, and calendar, time, leap year automatic conversion; Pulse output: Has the LED pulse and electric pulse output in direct proportion to the measured energy; Communication Functions: with infrared interface, the infrared interface and RS485 interface independent with each other on physical layer; the damage of one communication interface does not affect the normal operation of other communication interface; load switch can be set according to need - internal or external.
