3-phase AC Voltage / Current Combined Panel Meter:
Introduction
YD912X Three Phase AC Voltage/Current Combined Digital Panel Meter measures and displays real time AC phase voltage, line voltage, and current with LED display in 3P3W or 3P4W network. It is programmable for node output and passive contact input. The transformation ratio of CT, PT can be set by keyboard. With its reliable performance, YD912X panel meter is an economical and practical AC voltage/current measurement device.
Model Description
YD9120:3 phase current, voltage input, 4 bits display,
YD9121:3 phase current, voltage input, 4 bits display + one RS485,
YD9122:3 phase current, voltage input, 4 bits display + one relay contact output,
YD912A:3 phase current, voltage input, 4 bits display +one RS485 + one passive contact input + one relay contact output.
