Used KEITHLEY 2303 #9017361 for sale

KEITHLEY 2303 is a triple-output precision DC power supply. It is designed to provide precise current and voltage control to demanding research and production requirements. With an output voltage of 0-30V and a maximum output current of 3A 2303 is capable of supplying up to 90W of power. KEITHLEY 2303 has user settings for both current and voltage. It has selectable constant voltage (CV) or constant current (CC) operation that can be controlled either via an analog voltage or digital I/O. The unit can also be operated in a 'multi-range mode' which allows users to select either single or dual outputs independently, allowing them to make more precise changes in their output currents or voltages. 2303 also has selectable low-noise and fast-transient modes. In the low-noise mode output is automatically current regulated over the entire voltage range, thereby reducing noise by up to 30%, while in the fast-transient mode output is voltage regulated over the entire current range, increasing speed by up to 400kHz. KEITHLEY 2303 has a comprehensive set of features to maintain output accuracy and protection from over-current and over-voltage conditions. It includes a dynamic-response control loop, which adjusts the output voltage according to changing loads, providing more consistent results, while it also has a maximum-rate feature which limits the rate of change (ROC) rate. In addition, it includes a series of self-identification sensors that can detect a shorted load and protect both the supply and the load. Finally, 2303 has extended temperature range capabilities, allowing for operation at up to 65C ambient temperature and 100% load, while its low operating temperature of 10C provides greater output stability and efficiency. All these features make KEITHLEY 2303 an ideal precision DC power supply for a wide range of applications. Its 0-30V output voltage and 3A output current make it suitable for applications such as testing, burn-in, and laboratory use, while its adjustable modes, self-protection features and low-noise operation make it optimal for more demanding applications.
