time2024-11-21

Programmable DC power supply it is a power supply device that can adjust voltage and current through digital or encoder input. In addition to applications in professional fields, programmable DC power supplies also have many applications in daily life.

Main Functions of 1. Programmable DC Power Supply

constant voltage and constant current control

the programmable DC power supply has a constant voltage and constant current control function. Through digital or encoder input, the output voltage and current of the power supply can be precisely controlled. The flexibility of this power supply makes it suitable for a variety of application scenarios, such as scientific experiments and research, industrial production, and electronic equipment maintenance.

Tracking function

some programmable power supplies also have a tracking function, that is, all outputs will be controlled at the same time, and by keeping the voltage consistent with the preset voltage, they are all subject to unified command. For example, if voltage 1 changes from 10V to 12V, then voltages 2 and 3 will change from 5V to 6V, and voltage 4 will change from 20V to 24V. When one of the outputs reaches the maximum current limit, all other dependent outputs will also enter the current limit state at the same time.

Induction function

in order to solve the problem of unstable load voltage, the programmable DC power supply also has a sensing function (SENSE mode). In the normal mode, the voltage is directly loaded on the load through the wire to maintain the stability of the load voltage. However, since the load current will produce a voltage drop on the connecting wire, the actual load voltage should be equal to the power supply output voltage minus this voltage drop. By using the SENSE terminal, the voltage across the load can be measured directly. Since the current in the SENSE wire is small, the resulting voltage drop is negligible, so that the voltage induced by the power supply is actually the true load voltage. The power supply equipment will increase its output so that it is equal to the sum of the conductor voltage drop and the required load voltage to realize the compensation of the conductor voltage drop and make the load truly obtain the set voltage value.

arbitrary waveform power supply

some programmable power supplies also have arbitrary waveform editing capabilities, that is, the ability to generate time-varying waveforms. These programming waveforms can be single pulses or repeated continuous waveforms. Such signals can be freely defined within the scope allowed by the instrument specifications and stored in the instrument. Such signals can be defined via RS-232, IEEE-488 or USB interfaces.

Modulation function

some programmable power supplies also have an external modulation function that allows two sets of outputs to be modulated using terminals on the rear panel. Regardless of the power level, the distortion of the linear output components is very low to facilitate external modulation.
