max.Voltage 50V or 85V or what...?

Hi, in the datasheet max.85V is mentioned, on the board printed is max.50V, what is the technically maximum voltage the board can handle? I am asking the technical maximum not the "security". Also in the schematics no max.voltage is mentioned for the capacitors, any idea what it is?

thanks.

Recommended voltage range input for this module is 85 volts which is also the same recommended voltage for the POWERSTEP01 device.

Absolute MAX voltage is 95 volts for the same module and the same POWERSTEP01 device.

Found this detail through the datasheet for the POWERSTEP01:

and the BOM (with capacitor voltages) is posted on this landing page:
