A DC Power Supply is a standard piece of test and measurement equipment widely used in areas of education, circuit test, military R&D, etc. to power and tests the circuit system.

Types of DC Power Supply

There are many different ways to classify the DC power supply, such as single vs. Multi-channel, Linear vs. Switching, Bipolar vs. Unipolar, programmable vs. nonprogrammable, etc.

Basic points to consider in choosing the DC Power Supply

No matter how to classify the DC power supply, there are some basic points that need to be considered in choosing the right one, including:

• Number of output channels

• The power requirement of the load or circuit

• Safety features such as voltage and current limits to protect the load

• Setting resolution

• Load regulation: which means how well the regulator can maintain its output with a load current change, and usually is measured in millivolts (mV) or as a maximum output voltage.

• Ripple & noise: Noise is any added and unwanted electronic interference, and ripple is the small variation in voltage when AC is transformed into DC. These are typically combined into one measurement.

• Overvoltage protection: Sometimes output voltages can exceed their nominal values and can damage the load. Overvoltage protection is a circuit that shuts down the power supply should the voltage limits be exceeded.

To meet the high response, high stability, low ripple, and noise requirement during the electronic test, Suin Instruments has developed several series of Programmable DC Linear Power Supply, including SK33231/33251, SK3323/3325/3503, SK3323J/3325J, SK10000 Series, in which SK3325 can output 32V/5.1A signal in two channels, and can work on serial or parallel mode to increase the voltage or current, with 10mV/1mA resolution, and low ripple and noise.
