LM317T Voltage Regulator with Pass Transistor

Order the KZX1250 at www.adicorp.net The KZX1250 is a brand new PWM, not to be confused with any other PWM; The KZX1250 has an on board computer with advanced features that make it virtually bulletproof and safe to use, no other PWM can match it. Don't trust any PWM under your hood. With the KZX1250 you know you are safe and that your PWM is designed to handle tough situations that most other PWM's were never designed to. Start out with a computer that digitally generates the pulses. Send the output through Schmidt triggers to get a sharp squarewave which is then fed to a high speed MOSFET driver and finally to 8 PowerPak MOSFET's through their own individual driving resistors. The efficient design means it runs super cool. How cool is that? The KZX1250 does not have a heatsink because it just doesn't get very hot; just a small 40mm fan. With 50 amps going through it at max frequency, the KZX1250 enclosure doesn't even get warm and the protruding circuit board gets luke warm, you can squeeze it between your two fingers without getting burned! As you'll see in the video, the KZX1250 has short circuit protection. Automotive fuses can take up to 100 miliseconds after its rated current is reached before opening. That's a tenth of a second; which might seem fast to you, but to semiconductors, it is like a year! Fuses are activated by heat and the same heat that the fuse sees is the heat that the MOSFET's see as well. The KZX1250 opens the circuit in less than 1 millisecond so ...
