Problem: The 446x and 445x series DSA boards have a rated maximum voltage range of 42.4 volts. Why is the voltage greater compared to the 447x series (10V), and why is it a seemingly odd number? Solution: The 446x and 445x DSA boards are rated for an overprotection of 30 Vrms, which result in a protection for peak voltages of sqrt(2)*30 = 42.4.
