RSA320Y Three Phase LCD Digital Current Meter | Panel Mount Ammeter
Gerenal
The panel type digital display three-phase current and voltage meter is designed to meet the intelligent monitoring and energy measurement requirements of power systems, industrial and mining enterprises, public facilities, smart buildings, and other occasions. It can accurately measure all commonly used electrical parameters in the power grid, such as three-phase AC voltage, three-phase AC current, and also comes with 485 communication function.
Feature
*Dedicated Three-Phase Measurement – Accurately measures AC current (RSA320) or voltage (RSV320)
*Four Panel Sizes – 120×120mm, 96×96mm, 80×80mm, and 72×72mm for flexible installation
*Dual Display Options – Available in easy-to-read LED or LCD screen for real-time data visualization
*Easy Installation – Includes specified cutout dimensions (106×106 mm, 89×89 mm, 76×76 mm, 67×67 mm)
*Compact Design – Only 38mm deep for space-efficient cabinet integration
