The 2230-30-1 from Keithley is a programmable triple channel DC power supply. It combines 3 channels of output power to cost effectively characterize and test wide range of devices, circuit boards, modules and products that require more than one power source. The model 2230-30-1 includes two 30V/1.5A channels and adds a 6V channel with up to 5A output for powering digital circuit. It has 1mV/1mA setting resolution with ±0.03% + 10mV/±0.1% + 5mA setting accuracy, 1mV/1mA meter resolution with ±0.03% + 10mV/±0.1% + 5mA meter accuracy. This multichannel power supply offers an excellent combination of performance, versatility and ease of use to maximize the information from characterization or test as quickly and as easily as possible. It complies to European union EMC directive, USA: nationally recognized testing laboratory listing UL61010-1-2004, Canada: CAN/CSA C22.2 No. 61010-1 2004. It is used in circuit design, electrical engineering student labs, materials research and automated test.
