• 3-phase PFC and LT8312

    We have a legacy power supply that has to be redesigned from the ground up. The input is 115 Volts, 400 Hz, four wire, three phase Wye connected. The desired output s a single DC voltage to feed downstream DC-DC converters, which will be designed separately…

  • RE: 3-Phase 4-wire in to 3-Phase 3 Wire

    Good Afternoon

    The ADE7878 can be configured to accept multiple different configurations including 3 phase 4 wire and 3 phase 3 wire wye and delta.  Our FAQ:  AN-639 that is available on our website has detailed diagrams of each connection on pages 12…

  • ADUC843BCPZ32-3

    你好，

    咨询下单片机ADUC843BCPZ32-3 的技术问题：

    1.）参照DATASHEET, PSEN脚在代码执行模式下应该输出高，实际输出为低（0.005V左右）。

    2.）PSEN脚最大允许输入电压电流各为多少？

    3.） 代码运行过程中，PSEN管脚可否通过电阻上拉到电源？

    请给与大力支持！

    谢谢！

  • Divider-by-3 duty cycle

    Hello,

    I need to use a divider-by-3 device in my product.

    It requires to output a signal with 50% D.C.

     Input is a 25-100MHz SE signal.

    Output is a divided-by-3 differential signal.

     Can you confirm the following:

  • ADE7880 - 3 phase 3 wire delta configuration

    Hi,

    As per the ADE7880 datasheet pg. 43, in three phase three wire delta configuration, Phase B active, reactive and apparent powers are 0.

    So, I would like to know if there is a way to find out the Phase B power data in three wire delta configuration…

  • ADF4355-3

    In ADF4355-3  frequency synthesizer , 

    can  i use both RF outputs A and B at the same time ? 

    because iam using this IC to generate LO for two channels at the same time .

    what is the Rf output level of the both A and B at 4 GHz ?
