The DMTME series devices are digital multimeters for measuring the most important electrical quantities in single-phase and three-phase networks at 230/400 V AC as effective values (TRMS), including maximum, minimum and average values as well as active and reactive power. The measured values are shown on four red 7-segment LED displays. This enables simple and clear recording of various measured values of the individual phases and the entire network at a glance. The DMTME-I-485 multimeter includes the functions of a voltmeter, ammeter, power factor meter, wattmeter, varmeter, frequency meter, active and reactive energy meter in a single device. This results in significant financial savings thanks to better use of space and time saved on wiring, as well as the advantage of clear measured value displays on a single device. An integrated RS-485 interface is used to communicate measured values and alarms via a Modbus network. The device is also equipped with two digital relay outputs. These are fully programmable and serve as either a pulse or alarm output. They are designed for an auxiliary supply of 230V and 400V AC.
