Hello,
I'm currently in search for a fast switch that can pass 20A-25A and 20V-50V pulse train at 25% duty cycle and ~ 2kHz-10kHz through a purely resistive load. I found this "Fast Square Wave Pulser" from BEHLKE that claimed to be able to do so. From their instruction manual, the power supply requirements are : 15VDC @ 0.4mA/kHz and 120VDC @ 0.2mA/kHz.
Now, assuming my pulse train is at 25% duty cycle and 10kHz, the current requirement would be about 40mA and 20mA (6mW and 2.4mW). I don't know how the switch can provide (20A*20V) = 400W!
Could someone please help clarifying this?
Here is the link if anyone is curious: http://www.behlke.com/pdf/datasheets/fswp_instructions_v1.pdf
Thanks in advance!
