TPR series output DC regulated power supply

TPR series output is a high precision power supply which is composed of two way adjustable output power source and fied output power supply. With 3 sets of four bits and a half (DF 4 and a half), respectively, the output voltage of the two power supply, the current value. Two way adjustable output power with voltage and current automatic function conversion, the circuit by adjusting the tube power loss control circuit, operational amplifier and with temperature compensated reference regulator is composed. So stable and reliable circuits, the output voltage of the power source can from 0 nominal voltage value between any adjustment, in the steady flow state and the steady flow of output current from 0 nominal current value can be adjusted continuously. The two channels can be arbitrarily connected in series or in parallel, and simultaneously can be carried out by a main current in series or in parallel. In series, the maimum output voltage is up to two or two voltage ratings. In parallel, the maimum output current is up to the sum of two current ratings. Another fied output 5V power supply, the control part is composed of monolithic integrated voltage regulator. Three sets of power supply have a reliable overload protection function, output overload or short circuit will not damage the power supply. This series power supply has the characteristics of small size, good performance and novel style, which is the preferred power source for scientific research, colleges and universities, factories and electronic equipment maintenance and other units.

3, other: dual power supply can be carried out in series and parallel (4 bit display without series, parallel, without a fied 5V/3A outputIn series, the output voltage of the main power supply can be adjusted by the main power supply, and the output voltage of the main power supply is strictly tracked from the output current of the power supply. Parallel flow can also be the steady flow of output current is regulated by the main power supply. At this time from the power supply output current strict tracking the main power output voltage values.
