Multifunctional panel multimeter for monitoring parameters of three-phase electrical network with Modbus RTU communication
Intended use:
DMM-5T is a multifunctional microprocessor-based multimeter designed for monitoring the parameters of a three-phase electrical network. The multimeter enables high accuracy measurements of all basic network parameters such as phase voltages and currents, line voltages, frequency, active, reactive, apparent power and power factor. In addition, the multimeter allows full four-quadrant measurement of energy (both input and output to the network).
A front-panel multifunction display and LEDs are used to monitor the measured quantities and configure the device. Programming of the multimeter is enabled by a four-button keypad. The built-in RS485 interface, and the implemented MODBUS RTU communication protocol, ensures the multimeter's communication with a wide range of industrial devices and programs.
Operation
- indirect or direct (>5 A) measurement of phase currents
- indirect or direct (>230/400 V) measurement of phase and phase-to-phase voltages
- frequency measurement
- measurement of active, reactive and apparent power
- minimum and maximum values
- measurement of power factors
- four-quadrant measurement of energy consumed and returned to the network
- measurement of energy in 4 tariffs
- monthly settlement of energy
- impulse output of OC type (open collector) for energy indicators
- communication with external devices via RS-485 port and MODBUS RTU protocol
NOTE!
For RS-485 network it is recommended to use LT-04 termination modules.
