FUJI AC POWER MONITOR PPMC SERIES

FUJI AC POWER MONITOR PPMC SERIES This monitor is a compact-sized and multi-functional power measuring device capable of measuring active power, reactive power, power-hour integration, reactive power-hour integration, power factor, frequency, etc. according to the AC voltage and AC current input with single-phase 2 wires, single-phase 3 wires and three-phase 3 wires systems. Because voltage and current are read in at a high speed, even a significantly distorted waveform can be exactly measured. Via communication, the measurement data is transmitted to the host. The measurement data can also be acquired. Since measurement is carried out in each circuit, and equipment size is small, the monitor can be mounted on a small power distribution board. Therefore, a system can be configured economically. This is advantageous for environment control and energy saving. With the use of a clamping type current sensor, the current is measurable without rewiring the existing circuit.

Power-hour integration and reactive power-hour integration are backed up to the memory with a built-in backup battery. An internal clock function is also backed up. As a backup battery, a lithium battery which has a service life of 10 years or longer ( at normal temperature) is used
