Laboratory Power Supplies



Laboratory power supplies for test, repair and research applications

Laboratory power supplies are used to supply power to various connected devices and in different application scenarios. The advantage over a classic power supply is the variable output with which the current and voltage can be optimally adapted to different devices and applications. Therefore, laboratory power supplies are ideal for maintenance, research and development.



What to look for when buying a laboratory power supply unit

Depending on the area of application, there are different requirements for a professional laboratory power supply. If several devices are to be connected to the laboratory power supply at the same time, it needs several outputs. However, the number of outputs differs among different models. Therefore, the number of outputs should be taken into account when choosing the right laboratory power supply.
Another important decision factor is the power, as well as the maximum output voltage and current. Therefore, a laboratory power supply should be chosen that can provide sufficient power for the specific application. 


Last but not least, attention must be paid to the accuracy with which the device operates. A distinction must be made between the display accuracy and the setting accuracy. The display accuracy indicates the degree to which the accuracy between the displayed current and voltage values matches the actual output values. The setting accuracy, on the other hand, refers to the accuracy of the adjustable setpoints.
