August 1, 2013 - CD Automation introduces DC power line filters supporting 1500V photovoltaic panels. The filters maximise the operating DC voltage to the limit of the European Union’s Low Voltage Directive (LVD). The inverter filters allows for both single- and multi-stage performance options, to mitigate electromagnetic interference (EMI) scenarios. Their high voltage means they have lower current, thereby minimising cost by decreasing losses from heat dissipation. The products are ideal for inverter manufacturers seeking field-proven power line filters designed specifically for this task.
The two types of EMI Inverter filters - the RP300 series of AC Inverter filters suitable for wind turbines, and the RP600 series of DC filters – are designed for the photovoltaic inverter industry. The DC filter is installed between the solar photovoltaic panel and the inverter, thus helping to control conducted emissions on the panel side of the system and therefore significantly reducing the potential for high-frequency (HF) interference radiation off the panel. The filter also protects the solar panel from HF stray and leakage currents which can cause premature aging in the photovoltaic modules.
