Description
The UMD 98 is a high-performance front panel installation measuring device and replaces all analogueue measuring devices. It measures 3/4-phase current and voltage in 4-quadrant operation in class 0.2 and thus the work in class 0.5s as well as all usual line sizes, e.g. harmonics up to 50. Harmonious. The device is connected via current transformers with N/5 A and N/1 A. It maps the power quality according to EN 50160, EN 61000-2-2, EN 61000-2-4, EN 61000-2-12. It has a brilliant large color graphic display. The UMD 98 is conveniently operated via 5 function keys. It has two analogue inputs for RCM measurement. It can be used in 230/400 V TN-S systems. It has a large 512 MB memory and an integrated web server. The device can be accessed via the Ethernet interface (with 5 ports) and the mini-USB connection on the front. This means that Internet protocols can also be read in and PLC and building control systems can be easily connected. Digital inputs/outputs and a serial RS485 interface are also integrated. For network analysis, the measuring device can be extended by the firmware modules PQ S and GO. The device is parameterized or visualized with the ENVIS software. The CPU operates at 25.6 kHz.
