Nowadays, with the continuous development of various electronic equipment, they also have higher requirements for DC power supply. Compared with electronic equipment, it is impossible to meet the power supply requirements with a single DC power supply, so different DC power supplies are needed to power electronic equipment. Programmable DC power supply is of this kind.

Several functions of programmable DC power supply

(1) Power supply with arbitrary waveform

Some programmable DC power supplies have the function of arbitrary waveform editing, that is to say, generating waveforms that change with time, and generating waveforms corresponding to voltage and time interval parameter lists. The frequency of this signal is determined according to the time interval of each node. These waveforms can be single pulses or continuous waveforms.

(2) Tracking function

In some programmable DC power supplies, there is an inter-channel linkage function, which means that all outputs can be controlled at the same time to keep the voltage consistent with the preset voltage, so that they can exert unified command. If the leader is in the current limiting state, the subordinate in other places will also be in the current limiting state.

(3) induction function

In normal mode, the voltage is applied directly to the load through the wire to maintain the load voltage stability, but the load current will cause voltage reduction on the wire. Thus, the actual load voltage is the output voltage of the power supply minus the voltage drop. In some cases, the voltage drop formed by the output of low voltage and high current can not be ignored. The induction function can know how much the real load voltage is, realize the compensation of the voltage drop of the wire, and obtain the real set voltage value
