iso685-S-P+FP200 - Erdschlussüberwachungsgerät für AC/DC
Product description
The ISOMETER iso685 is an insulation monitoring device for IT systems in accordance with IEC 61557-8. It can be used universally in AC, 3(N)AC, AC/DC and DC systems. In AC systems, extensive DC-fed system components may also be present (e.g. power converters, inverters, controlled drives).
Device variants:
iso685-D:
The iso685-D device version has a high-resolution, graphical LC display and controls for direct operation of the device functions
Operating elements for direct operation of the device functions.
iso685-S:
The iso685-S device version has no display and no operating unit. It can be used in
Used in combination with FP200 and is operated indirectly via this.
Parameterization can also be carried out via the web browser or a COM465.
Option "W"
The device variants are optionally available with the W option for extreme climatic and mechanical
mechanical stresses.
