Variable Lab Power Supply 0-24V / 4A

Variable lab power supply 0-24V / 4A, it is a laboratory power supply with output voltage continuously adjustable from 0 V to 24 V DC, remote voltage sense capability (Sense internal/external). It has output current limit which is continuously adjustable from 0.04 A to 4 A and output current which can be limited continuously or output shut down (Limit/cut).

Remote sensing means that there are actually two extra wires which sense the delivered voltage at the load and compensate for any voltage drop along the cables which carry the delivered electric current. This improves voltage regulation at the load significantly but needs two extra wires for the sensing. A switch will allow internal sensing at the output terminals for easier operation when remote sensing isn't necessary.

About Power Supply
A power supply is a device that supplies electrical energy to one or more electric loads. The term of "power supply" is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy.
A power supply may be implemented as a discrete, stand-alone device or as an integral device that is hardwired to its load. In the latter case, for example, low voltage DC power supplies are commonly integrated with their loads in devices such as computers and household electronics.
