What is a Mechanical Mod?

[Zaryk]

That's what I thought, Zaryk feels otherwise.

That mod works just like any other regulated device. I never said the pot was bucking anything. I said the pot replaced the screen and buttons. It uses a chip just as any other regulated device does. Which is exactly what I said in post #15.

So the regulation chip does lossless DC to DC conversion rather that PWM?

hmmm... I always understood voltage drop to be anytime a current passes thru a resistor ( no matter how small) creates a voltage drop... be it a coil, switch, minimal connection, metal ( even silver)....

Exactly.

Afaik the tesla invaders do PWM and don't have the (now) standard board in them other tesla mods have.
At least it's advertised as a PWM mod on multiple sites (but they may be wrong, wouldn't be the first time).

Yes, it works just like a mod with a screen and buttons, but is always in variable voltage mode.

It isn't a pwm. I am 100% sure. Even their own website says the pot is for voltage adjustment. A pwm does not adjust voltage, they always fires full power, but only adjusts the on off frequency.

I know what pwm is. By adjusting the duty cycle you adjust the effective voltage though, which can be seen as equivalent to a certain DC voltage level (like with raw rectified AC). If in addition the output isn't raw but filtered in some way you get pretty close to a DC line. So you can kind of say the voltage is adjustable even with PWM.

As I said the shops I based my guess on may be wrong. I can't seem to find any info to reliably tell if the tesla invaders are PWM or not (both Phil and Daniel haven't fed the output into their scopes).

Edit: found this image of the board

and it indeed appears it is not a PWM board. So Zaryk is right, point conceded, the device is a DC output dialed by a potentiometer.

Almost every large scale production mod with a potentiometer is actually like that. I searched far and wide for a non-custom built PWM for a while, with zero found. I think that steamcrave may have released one recently though.
