This kind of meter adopts large-scale IC circuit, RS485 communication ports with isolation, infrared communication port, LCD display with large screen and wide temperature scope, real-time clock chip, electromagnetic compatibility (EMC) and advanced SMT electronic components assembling technique. Based on fully consideration of user's power-consuming status and the EMC of power equipment, this new energy-measuring instrument is elaborately designed and manufactured in accordance with IEC standards, national standards and ISO9001 quality assurance system.
Measurement Function:
Time-Of-Use Measurement
1. Display and read instantaneous total energy of positive-active, reversal-avtive, positve-reactive, reversal-reactive and 4-quadrant reactive. TOU measurment for various total energy at maximum 8 tariffs.
2. Read total energy of positive-active and reversal-active for the current and previous 12 months. TOU measurment for various total energy at maximum 8 tariffs.
3. Display total energy and various tariffs energy of positive-active, reversal-avtive, positve-reactive, reversal-reactive and 4-quadrant reactive for current month, last month and month before last month.
4. Display and read the time of instantaneous freezing and zero-hour freezing and the total energy energy and various tariffs energy of positive-active, reversal-avtive, positve-reactive and reversal-reactive when freezing occurs.
Time-Of-Use measurement of Maximum Demand
Display and read the total maximum demand and various tariffs maximum demands and their occurrence dates and times of positive-active and reversal-avtive for current month, last month and month before last month.
Display and read the total maximum demand and the occurrence date and time of positive-reactive, reversal-reavtive and the 4-quadrant reactive for current month, last month and month before last month.
Balance Power Alarm
1. Two programmable alarm levels: Balance power alarm and balance power emergency alarm.
NMeter Event Recording
2. Detection and recording of cover opening, timing recording, programming event recording, maximum demand recording, time zone modifying recording, power purchasing recording, alarm recording and emergency alarm recording.
