ISOMETER® isoNAV685-D

Устройство ISOMETER® isoNAV685-D предназначено для контроля сопротивления изоляции сетей IT по стандарту МЭК 61557-8.

Оно используется в сетях 3(N)AC с номинальной частотой 60 Гц.

ISOMETER® for IT AC systems with galvanically connected rectifiers or inverters and for IT DC systems (IT = unearthed systems).
Automatic adaptation to the existing system leakage capacitance.
Combination of AMP^PLUS and other profile-dependent measurement methods.
An adjustable response value for insulation monitoring in the range of 1 kΩ…10 MΩ (factory setting = 5 kΩ) and a response value of 150 V for the DC offset voltage.
High-resolution graphic LC display for excellent readability and recording of the device status.
Connection monitoring (monitoring of the measuring lines).
Automatic device self test.
Graphical representation of the insulation resistance over time (isoGraph)
History memory with real-time clock (buffer for three days) for storing 1023 alarm messages with date and time.
Current or voltage output 0(4)…20 mA, 0…400 μA, 0…10 V, 2…10 V (galvanically separated) which is analogous to the measured insulation value of the system.
Freely programmable digital inputs and outputs.
Remote setting via the Internet or Intranet (Webserver/Option: COMTRAXX® gateway).
Worldwide remote diagnosis via the Internet.
BCOM, Modbus TCP and web server.

AC/DC main circuits with directly connected DC components, such as rectifiers, converters, variable-speed drives
Systems including switch-mode power supplies
Systems including frequency inverters
