programmable DC power supply

What is a programmable DC power supply? A programmable DC power supply is a process in which instructions are compiled and fed into a machine in a sequence of operations so that the machine runs automatically according to the instructions. What is a programmable DC power supply used for? Programmable DC power supply or power supply. As for programme control, this means that the output of the power supply can be programmed and controlled. Programmable DC power supplies can generate stable high-power industrial frequency voltage and current signals with adjustable range, frequency and phase angle. It is mainly used for testing and verification of current, voltage, phase, frequency and power meters; it can also be used to verify the basic error, creep and sensitivity of standard power energy meters.

We can't live our daily life without programmable DC power supply. When selecting a DC power supply, there are many factors to consider and many parameters involved. It is because of the many parameters that people often feel overwhelmed and don't know what to do. To help you choose a programmable DC power supply, let us go over the factors you need to consider when selecting a programmable DC power supply.

Programmable Rise Time: This is an area of concern for many test applications, such as LED testing. The transient current during start-up can be much higher than the LED operating current, work steadily and damage the LED device.

To prevent damage from excessive peak transient voltages during start-up, the power rise time of the measurement device can have a programmable DC supply current slew rate control function and constant current priority to reduce LED overshoot supply voltage and current.

Battery simulation function: test power circuits or devices in real-world situations, you can use a test source with battery characteristics. For example, change the internal resistance of a programmable DC power supply so the voltage applied to a battery-powered device will fall within the internal resistance of the battery. Programmable DC power supply and programmable output resistance, do not underestimate the programmable resistor, which can complete the simulation of the internal resistance of the battery, power supply battery performance simulation is key.
