0-30v 0-10A variable power supply with adjustable voltage and current

0-30v 0-10A Variable Power Supply Adjustable Voltage and Current

Overview

Variable power supply with voltage and current controls 1-30 Volts and 0-10A. Both voltage and current can be controlled by potentiometers, and multi-turn potentiometers facilitate high-precision settings. Output load should be less than 10 amps. And it requires a large radiator with a cooling fan for effective cooling. A DC voltammeter is also required to monitor the output. Components required: TIP3055 and BD139 Transistors LM7805 and LM317 Voltage regulator 10k, 220 ohm resistor + 1 LED 10k multi-turn potentiometer 2x 1N4007 diode 1x 5v DC cooling fan 1x DC voltmeter and ammeter

Print driver issue: Is the printer Form required?
I made a printer driver, and then printed in Paint, and found that DrvEnablePDEV was entered, but DrvDisablePDEV was called immediately, and even DrvStartDoc was not entered. Is it because there is no
I accidentally found a chip, but I don't know what it is for after looking at the silk screen. Does anyone know?
RT I accidentally saw a chip in SOP8 package, with ATMLH846 46D (or 460) printed on it. I was curious to know what it was for, and I searched online, but I couldn't find it. I guessed it was from Atme
