Product Description

Chapter 1. General introduction

The 3U(3I) combined meter is used to measure and display the direct digital reading of voltage/current value in the three-phase electrical line. The UIF combined meter is used to measure and display the direct digital reading of voltage, current, and frequency values in the single-phase electrical line. One meter can finish the measuring tasks of three common meters. It can support the analog output, alarm, and RS4485 communication function by the installation of different functional modules. And it can also select the multiple functional modules at the same time to make it with the alarm, transmitting, and communication functions.
