The UMD 707DC is a compact high-end DC meter for DIN rail mounting. It measures 5-channel direct or alternating currents, as well as direct and alternating voltages including the power quality (up to the 128th harmonic) and voltage dips from 40 μsec.
The measurement is carried out using the JS H-series current transformers (Hall Effect). The unit 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 the web browser. This means that Internet protocols such as NTP can also be read in.
PLC systems and building management systems can be easily connected via Modbus TCP. Digital inputs/outputs and a serial RS485 interface are integrated. With the firmware module GO, oscilloscope functions for current and voltage are activated and trigger signals for limit value events are set. A PT100 input is also available.
A special power supply unit (15V) is required to supply the JS current transformers (Hall Effect). The DC Power Compact6 power supply unit is included in the scope of delivery of the UMD 707DC.
The unit is mainly used for measuring direct and alternating currents.
