UMD 705
The UMD 705 is a compact power quality meter with data logger for DIN rail mounting. It measures 3-phase current and voltage with up to 3 tariffs in 4-quadrant operation and the work in class 0.2s, as well as all common mains quantities, e.g. harmonics up to the 50th harmonic. It optionally maps the power quality according to EN 50160, EN 61000-2-2, EN 61000-2-4, EN 61000-2-12 with the PQ S firmware module. It has a large 512 MB memory. The unit can be accessed via the Ethernet interface and live measured values can be viewed via the associated web server using a web browser. This means that Internet protocols can also be read in and PLC and building management systems can be easily connected. Digital inputs/outputs and a serial RS485 interface are integrated.
The UMD 705 can also be used as a Modbus master for connecting up to 31 Modbus slaves in network structures. With the optional firmware module GO, oscilloscope functions for current and voltage are activated and trigger signals for limit value events are set.
Use
The unit is used in building automation for monitoring the infrastructure.
