Single-phase Multifunction Electricity Power Meter

Single-phase Multifunction Electricity Power Meter,Electric Energy Meter,kWh Meter,Watt-hour Meter KN1110C Multifunction Meter meets the IEC 61036 (Class 1) standard for multifunctional energy meters. The main features of the product include none physical adjustment components, digital signal processing, digital filters, digital error correcting, digital calibration, immunity to temperature fluctuation, and excellent stability. Due to its twelve times overload multiplier, the meter can record extremely low energy usage. KN1110C can also measure voltage, current and power accurately. The basic functions of KN1110C include data processing units of 4-tarrif active bidirectional (import and export) energy; tariff switch can be controlled through internal clock. Infrared data communication protocol meets IEC 62056-21. User can configure meters parameters and read meters data using PC. Power Supply: Current(mA)Power consumption(VA)Power(W)220V(transformer)<5<1<0.8110V(transformer)<4<0.8<0.5Pulse Output: There is one channel of pulse output which will output fixed 80 ms wide telecontrol pulse upon both active import and export energy. The output is passive optical-coupling. Telecontrol pulse may also be used as verifying pulse. Maximum Demand Indication: Calculation method: rolling or block Calculation cycle: 5, 10, 15, 30, or 60 minutes Rolling interval: 1, 2, 3, or 5 minutes Recording range: 99.9999 kW Additional error: ± (0.5+0.05 Pm/Pn) % Pm - power value at Imax (cos=1.0) Pn - equivalent real power value on demand indicator Reset mode: manual, automatic Clock: Electric clock: displaying year, month, day, week, hour, minute, second; in 24-hour format. Error at 23±2: ±0.5 seconds/day Delay of Time Block Switch: Less than 0.1 second Back-up Battery: One extra button lithium battery is provided to act as backup power. Lifetime of the button lithium battery: ≥10 years. Data Output Interface: 1. KN1110C provides an infrared data communication which meets IEC 62056-21. 2. Baud rate can be 300, 2400 bps.
