N3-RHD type reactive power transmitter is a voltage and current signals were collected by the system, and passes the high-precision division multiplier operation, the measurement system reactive power, reactive energy system will be converted into high linearly proportional to the amount of output pulses, including: output for voltage pulse, no voltage pure contact (opto-isolated) output or relay contact output; and transmitter power constant (pulses per kWh) can have a variety of options to facilitate data collection, and can reflect the load (inductive or capacitive) the status of the system. The meter can be long-term continuous operation for non-electric energy as an automated billing system to monitor energy use of reactive power measurements. Using cross-phase reactive energy measurement: for frequency of 50Hz or 60Hz three-phase three-wire symmetrical balance measurement systems; reactive energy measurement using the phase shift method: apply to the frequency of 50Hz or 60Hz single-phase, three-phase three-wire balanced or unbalance measuring system, three-phase four-wire system, which is a unique phase shift circuit ensures the input signal is within the range of 40Hz-60Hz, not because of changes in signal frequency to produce additional errors, and S3 (T), N3 series reactive power Accuracy relative error is less than equal to 0.5%, 0.1%. Features The series of high accuracy, good conversion performance, good temperature characteristics, have lightning protection. Inverse measure of the ability of reactive energy having long-distance transmission capacity (4 ~ 20mA, 500Ω), fixed way, in line with DIN46277, can be mounted on the 35mm aluminum rails.
