UPM100/UPM101

Universal Power Monitor UPM100/UPM101

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.

Details

Features

  • 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.

Overview:

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.
Overview:

Power monitoring package SMARTDAC+ GM and UPM100 system measures and quantifies the electrical energy consumption for each assembly line.
No. You'll need to use a type of product matching the phase and wire type.
Yes. Select one with a secondary current rating of 1 A or 5 A. The consumption VA of the UPM100 itself is 0.2 VA, so check the rated load of the CT including the wiring.
If the integral power value is exceeded, it automatically becomes 0 Wh and the integral is recalculated.
The UPM100 is a compact power monitor that measures the following in industrial devices and other factory instruments: apparent, active, reactive, integral active, integral reactive, integral regenerated, and integral apparent power, instantaneous va...
Check the active power. If the active power turns negative or extremely small, check the items below. The active power is negative when the power is regenerating. Items to check Is the CT attachment orientation correct? Is a CT connected to th...
For power monitors, you need to set up CT and VT ratios. (In the case of the PR300 power monitor, phase, wiring method, voltage range, and other settings are required in advance.) However, even when you enter these settings, there are times when the ...
For each power monitor, normally you use 1 to 3 CTs. Single phase 2-wire = 1 CT; single-phase three-wire = 2 CTs; three-phase three-wire = 2 CTs, and three-phase four-wire = 3 CTs.
What are VT and CT ratios?
(ns-faq-power-12008-term)
Generally, when measuring high voltage and high current transformer signals, you use a VT (voltage transformer) and CT (current transformer). The ratios between the primary and secondary rated voltages and rated currents are the VT and CT ratios. For...
For low and high voltage measurement it is a D type ground, and for especially high voltage measurement it's an A type ground. (Use in combination with a Yokogawa power monitor. Note that the CTW series current converters are for low voltages.) ...
