The UPM100 is a compact power monitor that can be attached in industrial machinery etc. and measure instantaneous apparent power, instantaneous active power, instantaneous reactive power, instantaneous rms voltage and rms current of each phase, active energy, reactive energy, regenerative energy, apparent energy and instantaneous power factor.
The UPM100 can measure one of the single-phase 2-wire, single-phase 3-wire, three-phase 3-wire or three-phase 4-wire.
The UPM 101 measures the secondary side line of the existing CT by using a dedicated CT.
Various electric power and energy can be monitored by using a wide array of measuring functions.
Communication via RS-485 communication is possible.
The UPM100 and UPM101 is compact and can be mounted on DIN rail or a wall.
Good readability is realized by using a large LED display. In addition, since the 6-digit value with the decimal point which can move by key operation on a front panel is displayed, detailed electric power and energy can be checked.

*1: When "optional measuring function" is specified.
*2 Reactive energy LEAD and LAG are integrated. When "with pulse output" is specified, active energy pulse and reactive energy pulse are outputted. However, either LEAD or LAG is output for reactive energy pulse.
Improving manufacturing efficiency demands constant action - from uncovering operational waste to identifying areas for continuous improvement. Namely, we must always pursue a cycle of visualizing, analyzing, and solving energy saving challenges.
The MW100 can be used for measurement and monitoring at facilities that use solar heating and lighting.
Yokogawa Power Monitors measure energy in plants, such as power, current, voltage, power factor, etc. In addition, data acquisition for power, vapor, fuel, water, air, etc, and data monitoring using viewer software, are performed by connecting to the MW100 data acquisition unit.
The MW100 allows logging via communication of devices that support MODBUS servers. With no analog module required, costs can be reduced, and errors during A/D conversion are eliminated.
