The QE81WH module developed by Mitsubishi is a power measurement device. It accommodates several phase-wire systems, including single-phase 2-wire, single-phase 3-wire, and three-phase 3-wire configurations. With voltage circuit ratings of 110V and 220V AC for single-phase 2-wire and three-phase 3-wire, it can accurately monitor these setups.
For single-phase 3-wire systems, this module offers unique voltage ratings: 110 VAC between the 1—and 2-sides and between the 2—and 3-sides and 220 V between the 1—and 3-sides.
Regarding current measurement, the QE81WH supports multiple ratings: 50 A, 100 A, 250 A, 400 A, and 600 A AC, using a dedicated split-type current sensor for precise readings at the primary side. A 5 A AC measurement configuration is also possible by utilizing a current transformer (CT) capable of scaling to primary-side currents up to 6000 A.
This module can measure one circuit effectively by automatically detecting frequencies from 50 Hz to 60 Hz. Suitable for operating in environments with temperatures ranging from 0 °C to +55 °C, it is important to maintain an average daily temperature of +35 °C or lower. The humidity tolerance spans from 5 % to 95 % RH, provided no condensation forms.
Regarding storage, the module can endure temperatures from -25 °C to +75 °C, making it robust against varying conditions. It is designed to operate effectively at altitudes up to 2000 m.
Compliance with several standards, including EMC, LVD, UL, c-UL, and KC marking, ensures that the QE81WH meets necessary safety and regulatory requirements. This modular design is intended for installation inside control panels, making it a reliable choice for industrial applications.
