Questions about SpeedVal Kit

Hi, I am interested in purchasing the SpeedVal kit, but have a few questions about it before I buy:

1)     What is the maximum rms power that this platform can be used for? My understanding is 36kW (900Vmax x 40Amax). Is this correct? I intend to use it at 650V and 1.6A at 300KHz.

2)     How can I setup the safety enclosure shown in the DPT video that turns off the power to the kit if the lid is opened?

3)     I am interested in C3M0350120J, which comes in TO-263-7 package. However, the closest available power daughter card comes with C3M0075120J. Since they are footprint compatible, can I request to replace the C3M0075120J in the MOD-PWR-MM-C3M0075120J power daughter card with C3M0350120J?

4)     What is the maximum switching frequency of the PWM signal that I can inject into the daughter card? Is there a guideline for input signal frequency to fs ratio? I plan to inject a 300KHz signal at the input. What should be my switching frequency?

5)     Do you sell power daughter card in full bridge configuration?

6)     I am interested in using ADuM4146 gate driver card. In ADI’s UG, it says under “Equipment needed” that I would need the CGD12HB00D (2-Channel Differential Transceiver Companion Tool) for this gate driver card. However, I am not clear how to connect this tool in my test setup. Is this tool needed if I buy the SpeedVal kit and AduM4146 gate driver card?

Thanks,

Noman
