CheckSource 2.3 is a three-phase current source for cur-rents up to 6 A. The test currents will be generated with the same frequency and a user-defined phase shift to the volt-ages applied to the voltage inputs. Alternatively the test cur-rents can also be generated with a user-defined frequency
Advantages of the CheckSource 2.3
• Three-phase portable precision type source with single- phase mains supply
• Phase currents can be generated individually
• User friendly graphical LCD display to define currents, phase angles (symmetrical /
asymmetrical) and fre- quency
• Remote control of source by RS 232 interface
• Currents are generated with high accuracy and stabi- lized by digital and analogue control
