In a world where everything is claimed to be "best," what does "best" really mean?

If one looks up the definition of "best," it's clear that being best is not only subjective, but also tough to quantify.  So when we say a POWER-GATE battery isolator is the best battery isolator on the market, are we just being arrogant?  Are we just taking the same marketing liberties that we as the consuming public see day in and day out?  The "best" pizza in town.  The "best" battery money can buy.  The "best" window washing company.  The concept of "best" has become so commonplace that we've lost touch with what "best" really means.

So how does one define or measure the "best" battery isolator if every manufacturer claims to offer the "best."  From our perspective, it's very simple:  to measure the efficiency of  isolators (also known as rectifiers), you need to know what the voltage drop is at a given current level.  Many companies try to impress buyers by offering a zero or no-voltage-drop isolator.  This of course defies the laws of physics, but they hope the buyer doesn't know that.

At very low current levels, the voltage drop through any isolator will be very low.  But what is the voltage drop at 100 amps?  200 amps? or 300 amps?  The voltage drop at these elevated current levels is what truly makes POWER-GATE "best."  And we say that not because we are arrogant, it's because the numbers don't lie.

Perfect Switch, LLC owns the patent on a unique assembly process where the use of arrayed MOSFET's yields the absolute lowest resistance from the input to the output of a device. The resistance is so insignificant that heat sinking and airflow are not necessary.  So as you compare devices for your DC power management needs, if it looks like a giant heat sink, it does so for a reason....to dissipate heat.  If it were a "zero voltage drop" device, it would dissipate no heat and if it dissipates no heat, why does it look like a giant heat sink?  If it looks like a duck and quacks like a duck, you guessed it....it's a duck.

We've scoured the earth looking for competing technologies and we can say with absolute certainty that when you buy a POWER-GATE battery isolator, or you add a POWER-GATE solid state relay to your electrical system, you are buying the "best" that technology has to offer.
