isoPV335 + AGH-PV-3 Isometer
Product description
The ISOMETERs of the isoPV series monitor the insulation resistance of unearthed main circuits (IT systems) AC, AC/DC 0...793 V or DC 0...1100 V. Solar systems are often designed as IT systems in conjunction with inverters and isolating transformers. Thanks to the AMPPlus measuring method, which has been specially adapted for slow voltage fluctuations, device variants of the isoPV are available that meet the requirements of modern solar systems in particular. Due to large expansions and EMC interference suppression measures, these systems often also have high leakage capacitances to earth, which are taken into account by the isoPV through automatic adaptation to optimize the measurement time. It is particularly suitable for the voltage ranges required here and at the same time a low insulation level.
The ISOMETER isoPV is always used in conjunction with the AGH-PV coupling device. The separate supply voltage makes it possible to monitor the de-energized system.
