PQ Plus UMD 807E

The UMD 807 E is a built-in power-quality measuring device for mounting in the front panel 144 x 144 mm. It measures 3-phase current and voltage with up to 3 tariffs in 6-quadrant operation in Class 0.2 and thus the work in Class 0.5, as well as all usual network variables, e.g. harmonics up to the 50 most harmonic. It can be used in 400 V, 690 V as well as in IT networks. It can be about current transformer with N/5A and N/1A can be connected. It is the power quality according to ISO 50160, IEC 61000-4-30, EN 61557-12 and EN 6205 3-22. It has a large 512 MB memory. Via the Ethernet interface and the front-sided mini-USB connection can be accessed on the device. Thus are also internet protocols can also be scanned in and it can be easily connected PLC and building control systems The UMD 807 E has 2 analogue inputs and outputs, 4 digital inputs and outputs, an RS485 interface, as well as an integrated hour meter. Furthermore, the device is a Modbus master function, so it can be up to 31 slave devices are connected and routed. The sampling frequency is 6,4kHz. With the software ENVIS, the measuring device is parameterized or visualized. As an optional firmware modules for evaluation of the voltage quality according to EN50160, the PQ S module is available. With the firmware module Go to oscilloscope functions for current and voltage is activated and trigger signals for limit value events. The RCS module supports the round control signal detection. The ENVIS in the variant Basic is free of charge in the delivery.
