TPR3005T DC power supply is a high precision and high reliability of the constant voltage constant current power supply, which has a limiting step, short circuit protection, over-temperature protection, with a load capacity and other characteristics. This series of power supplies for laboratory, electronics production lines, maintenance of communications equipment, scientific research, production, teaching and other units necessary equipment. Operating conditions such as power supply overheating, the output in the output circuit cut-off, when the internal temperature returned to normal, the power output to restore the default state. The machine has perfect protection function to protect user equipment from being destroyed.
