CNW 173

DC filter for photovoltaik (2 lines)

CNW 173

Unique Selling Point


  • protection of solar cells from high frequency 
  • noise generated by the inverter
  • designed to conform to existing and planned
  • optional with current transformer
  • compact construction
  • low temperature rise
  • universal protection for all inverters
  • optional anti-surge protection

Description


Applications: The DC-filter surpresses grid-bound troubles of inverters for renewable energies like solar and wind power. 

  • Conforming to: VDE 0565-3/ IEC 950/ UL 1283
  • Test voltage: L-L 3000 V, DC 1 s; L-PE 3000 V, DC 1s
  • Climatic category: DIN IEC 60068-1
  • Overload: 1,5 x INenn 1 min / h

Technical Data


  • Nominal Voltage : 1000 V
  • Rated current : 25 A

OPTIONS: 

Integrated AC/DC current sensors type WKO/AT
The REO sensors use a Hall-effect device in their magnetic circuit to measure the primary current, which is electronically converted to a proportional output current. 
It measures frequencies up to 150 kHz.

  • Fast Response
  • Excellent linearity

 The current sensors are integrated into the filter and are ready for connection. There is no additional installation effort required. Attention! This option will change the mechanical dimensions of the filter!

 

Optional overvoltage protection CNW 7010

The CNW7010 provides efficient protection against power surges caused by switching, lightning and transients. A combination of gas discharge arresters and varistors provides multi-layer protection optimizing the benefits of each individual component and guaranteeing safe and fast discharge to ground. This ensures that the connected equipment continues to operate safely.
