Keithley 2231A-30-3 Triple Channel DC Power Supply
The Keithley 2231A-30-3 triple channel DC power supply is created for precise usage and testing in various domains. The unit comes with 3 independent outputs and delivers isolated voltage sources suitable for a variety of testing and characterization applications. The unit supports input voltages of 110 VAC and 230 VAC. The DC power supply 2231A-30-3 unit features a vacuum fluorescent display (VFD) for clear readouts of voltage as well as for current and varying power levels. The display provides real-time feedback assists to allow accurate adjustments during operation. Its design allows for straightforward control and monitoring in both manual and automated setups. It features two channels capable of providing up to 30 VDC at 3 A each and a third channel offering 0 to 5 VDC at 3 A.
The 2231A-30-3 triple channel supply unit comes with isolation voltage between any output and chassis reaches 240 V DC or peak AC with a maximum of 3 Vpk-pk at 60 Hz. This high isolation enhances safety and flexibility when testing high-voltage or sensitive circuits. Each output can be individually isolated or configured in different modes to suit testing needs. The triple channel DC unit 2231A-30-3 supports tracking mode which maintains a fixed ratio between the two 30 V channels when activated. This feature simplifies synchronized voltage adjustments across multiple outputs. The device also offers series and parallel modes by enabling combined voltage or current outputs for specific applications. The total power capacity of the unit is 195 W which helps to make it appropriate for hard electronic testing tasks.
The channels 1 and 2 can deliver up to 60 V combined with the meter displaying the total voltage in series mode. This setup is useful for applications requiring higher voltage levels. In parallel mode, the same channels can supply up to 6 A combined and is suitable for high-current applications without overloading individual channels.
The Keithley 2231A-30-3 triple channel power supply includes a North American power cord and supports standard AC supplies. It weighs approximately 7.1 kilograms (15.7 pounds) by making it useful for bench or rack mounting. It involves thermal management and compact design along with firmware updates and calibration routines which can be performed to maintain measurement accuracy.
