& BULB LIFE
kills most of your bulbs or lamps in an aircraft? Your startup of
the electronics. When you flip the power switch you get a huge inrush of
current into the lamps or bulbs until the electron current heats up the
filament. during that heat up time the filament wiggles and wobbles
causing fractures in the filament to start to break. Then
months later you lamp is out and your are back to the avionics shop for a
bulb change and a costly repair.
TPS-28 eliminates all that cost. with our soft start circuit, The
TPS-28 limits that inrush electron current. Saving you hundreds of dollars
and hours of repair time at the avionics shop.

Saving - operation of an Aircraft
Here is a typical scenario. You have 28 V and you
want to get to 5 Volts @ 6 Amps, so you think "I will use some power
resistors or a linear regulator because they are cheap"!!! You
just cost the customer 200 watts of needless power and heat every hour he
runs the aircraft. On top of that you may be burning up your aircraft
|What does it cost in fuel? Well if you do the
math, 200 watts comes out to be about 1/4 of a horse power to the engine.
It does not sound like much but add that fuel cost in and after hours of
flying its like adding another person to the aircraft. You have burned up
thousands of dollars of fuel. In the long run, those cheap power resistors
ended up costing your customer lots of money.
is the answer
|What is the difference between a linear regulator and
resistors verses the TPS-28? Well, everything in the world. The TPS-28 is
a switching power supply that only takes a small amount of power to
get to the 5 Volts or to whatever voltage you need. Switching
regulators use charging circuits and do not dissipate large amounts of
heat to do the power conversion.
||Is there any other way of doing low cost power
conversion? NO, not unless you can change physics. The TPS-28 has an
efficiency of about 90%. That's 80% better than power resistors or a
linear regulator. The real answer to the question is this: In
a very short time the TPS-28 more than pays for itself just in lower fuel
