Keithley 2220G-30-1 Power Supply
Programmable Dual Channel DC Power Supply, 30V, 1.5A, GPIB
The Keithley 2220G-30-1 Multi-Channel Programmable DC Power Supply is designed to efficiently meet the needs of various testing and characterization scenarios. Featuring two independent channels, this power supply is capable of delivering outputs of up to 30V and 1.5A, facilitating the testing of diverse devices, circuit boards, and modules that require multiple voltage levels.
This versatile power supply excels in both automated test systems and manual configurations, making it an ideal choice for labs focusing on quality and performance. Each channel operates independently and is electrically isolated, providing the flexibility needed to power circuits that are optically or transformer-isolated. This feature negates the necessity for additional power supplies, enhancing convenience without compromising performance.
One of the standout features of the 2220G-30-1 is its timer capability, which allows for unattended testing. This enables the unit to automatically turn off the channels after a pre-determined interval, safeguarding the device-under-test (DUT) from potential damage due to prolonged power application. Harnessing this functionality provides a strategic advantage for users looking to maximize test accuracy while minimizing manual oversight.
With a basic voltage setting accuracy of 0.03% and a current accuracy of 0.1%, rest assured that the voltage programmed for each channel is the voltage delivered to the load. Each channel features remote sensing terminals that compensate for voltage drops within the power supply leads, ensuring precision in the voltage at the DUT’s load terminals. This is a critical advantage over many other multi-channel power supplies lacking remote sensing capabilities.
The Keithley 2220G-30-1 offers exceptional load current measurements with a noise level of less than 3mV p-p, reinforcing its status as an essential tool both on the benchtop and within complex test systems.
