GF303D 120a 600v Portable Three phase programmable AC power source with current and voltage source
The programmable high-side current source supplies an adjustable current to a ground reference load. The first op amp stage sets a reference current based on the DAC output voltage. The second op amp stage acts as a current mirror that gains the reference current and regulates the current sourced from the output PMOS to the load.
High precision programmable Current Source is Software-Programmable. Abstract: A shunt regulator provides a constant reference voltage across a digital potentiometer that, in conjunction with an op amp and transistor, forms a software-programmable, voltage-controlled current source. With the addition of a few inexpensive miniature components, the hard-wired, voltage-controlled current source of yesterday.
The GF303D is a powerful and portable programmable three phase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability. The source is available in 12 A, 24A or 120 A.
The GF303D three phase portable programmable power source is a lightweight and portable current and voltage source based on newest technology and serves for solving this problem by simulating the required load conditions. Operation is performed by integrated 7" touch screen or via keyboards.
