Re: Victor 888 vs Jaguar for rookie drive train

Max,
I prefer the IFI Victor solution over the Jags. While many will point to the lack of limit switch input, non-linear output, calibration and PWM retention as cons, all of these issues are easily overcome with other solutions. The Victor is a rugged little controller that you can continue to use for years to come and be happy with it. If you search out other posts here on CD you will find that the differences are relatively minor. The linearity for instance is more a function of switching frequency, calibration is needed for all controllers and PWM retention is easily overcome with tywraps or other cable management. I personally find the fault modes on the Jag troublesome for many teams. High load current, low input voltage and over temp can set the Jag into fault which disables the output for a few seconds after the fault is removed. The Jag does let you know (if you can see the LEDs) when it has entered fault mode. However, having one side fault while the other still drives makes for interesting driver response.
