Power Supply and CB Report

We are interested in using a power supply of the HDP12-MD series for a medical device we are certifying. Even if the power supply is branded and full of certifications, we do not find references or the possibility of obtaining the CB Report a document necessary to proceed with the certification of our CB Report.

How can I get the CB report of the HDP12-MD?

Thank you

USB adapter output current enumeration

I came across your HDP05-MD05010U USB power adapter. I was reading a bit into the USB 2.0 terminology and have a question regarding this part’s output current. For any connected USB Device, does it provide the rated 1A max current right from the start? Or does it initially provide 100mA, enumerates and then provides higher currents to Device?

The display uses an ST7529 IC and I am currently following its datasheet to write a program on Arduino using its SPI interface to initialize this display.

I can verify on the scope that the SPI commands are going into the display in the right order, MSB first but I dont see initialization happening. The way we are verifying it... (More)
