how are typical specs of a imaging ultrasound machine power supply (just for the tx pulsers), and what kind of power supply usually used (linear, switch)?

For example, consider a 128 tx channels, bipolar square pulse transmitter +100V and -100V, prf (pulse repetition frequency) of 4khz, 5 cycles per pulse, and each transmitter could provide 2 amps current peak.

I like some information about my considerations above, are they correct specs?
Thanks
