PQ Plus UMD 705E Digital rail-mount meter
The UMD705 is a compact power quality meter with data logger for mounting on the DIN rail. It measures 3-phase current and voltage with up to 3 tariffs in 4-quadrant operation and the work in Class 0.2 s, as well as all usual network variables, e.g. harmonics up to the 50 most harmonic. It forms the option of power quality according to 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. Via the Ethernet interface, the device is accessed, and the associated web server live measured values via the web browser. Thus are also internet protocols can also be scanned in and it can be easily connected PLC and building control systems Digital inputs/outputs and a serial RS485 interface are integrated. The UMD 705 can also be used as a Modbus master to bind up to 31 Modbus slaves in network structures can be used. With the optional firmware module GO to oscilloscope functions for current and voltage is activated and trigger signals for limit value events.This text is machine translated.
