The UMD 807E is a built-in power quality meter for mounting in the front panel 144x144mm. 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 50th harmonic. It can be used in 400 V, 690V as well as in IT networks. It can be connected via current transformers with N/5A and N/1A. It maps the power quality according to ISO 50160, IEC 61000-4-30, EN 61557-12 and EN 62053-22. It has a large 512MB memory. The device can be accessed via the Ethernet interface and the front mini-USB connection. Internet protocols can thus also be read in and PLC and building control systems can be easily connected. The UMD 807E has 2 analog inputs and outputs, 4 digital inputs and outputs, an RS485 interface and an integrated operating hours counter. Furthermore, the device has a Modbus master function so that up to 31 slave devices can be connected and routed. The sampling frequency is 6.4kHz. The ENVIS software is used to parameterise or visualise the measuring device. The PQ S module is available as an optional firmware module for evaluating the voltage quality according to EN50160. The firmware module Go activates oscilloscope functions for current and voltage and sets trigger signals for limit value events. The RCS module supports ripple control signal detection. The ENVIS Basic version is included free of charge in the scope of delivery.
