Tool provides insulation voltage in wind turbines
Avago Technologies
Digital Optocoupler
Avago has released a 10 MBd Digital Optocoupler with high insulation-voltage ratings for power-supply and high-power motor-control applications such as wind turbines and communication interfaces.
The ACNV2601 single-channel, 10MBd digital optocoupler addresses market segments that need high data-communication rates, along with high insulation-voltage performance.
It is said to be the first optocoupler that combines 10MBd data rates while maintaining or increasing insulating voltage ratings.
ACNV2601 is designed to provide 7,500V rms/1min isolation voltage, 1,768V peak continuous working insulation voltage and 12,000V peak transient over voltage.
The optocoupler is pending IEC/UL/CSA regulatory certification for Reinforced Insulation against electric-shock applications.
Avago's internal shield between the AlGaAs light-emitting diode and photo detector helps guarantee 20,000V/us common-mode transient immunity performance with a common-mode voltage of 1,500V.
The high insulating voltages of the Avago ACNV2601 makes it suitable for applications with 690V power main voltages or high-speed, power-switching equipment that use high-voltage IGBTs.
Intelligent power modules and communication interfaces, such as RS-232/RS-485 and CANBus, will benefit from the combined high-speed and insulation-voltage characteristics of the ACNV2601.
Where conventional line receivers cannot operate, the ACNV2601 provides reliable logic interfacing and input/output buffering in the presence of extremely high ground or induced noise.
