Re: What is duty cycle?
If one searches on the IFI Victor web page, they state that the Fet chop rate or PWM fequency is 120 HZ. The controller must send a low for at least 8 ms before the victor can recieve the next updating 1 to 2 ms pulse. The press release for the new speed controler did state that 20 khz was the fequency for the new one. For many reasons they may find that a high fequency ia not always a good thing. The big change with the new speed controller is the powerful 32 bit microcontroller and the can buss interface. The controller is reprogramable so as the needs of First change the controller can be upgraded and it's capabilities expanded.
