Description
A mixed-signal board rarely needs three equal rails. The Keithley 2230-30-1 power supply splits its three isolated outputs to match: two for analog work and one for logic. Lost in HCM lists it for rental and sale, and it arranges service on request.
Two analog rails and one logic rail on the Keithley 2230-30-1 power supply
Channels 1 and 2 each reach 30 V at 1.5 A. Channel 3 reaches 6 V at 5 A. That last channel suits a logic or microcontroller supply, because it trades voltage for current. Meanwhile the two 30 V channels can bias amplifiers, sensors or reference circuits. The listing gives 120 W as the maximum power for the whole unit. So plan your total load before you start, because the channels share that budget. Also keep the 5 A limit in mind for channel 3.

Everyday work for the 2230-30-1
Engineers use a unit like this for research, design verification, teaching and automated test. For example, a sensor board might take its analog rails from channels 1 and 2 and its processor from channel 3. In the product photo, three channel readouts sit on one display, with three pairs of terminals on the right. One USB cable then links the whole bench to a PC.
However, the listing names USB only. If your rack needs GPIB or serial, ask Lost in HCM about the other 2230 models.
Rent or buy the Keithley 2230-30-1 power supply
Rent it for a prototype that will ship soon, or buy it for a permanent mixed-signal bench. Whether you rent or buy, request a quote from Lost in HCM and include your dates, leads and software needs. Before the first power-up, confirm polarity and grounding, and follow the Keithley manual for safe limits. You can also scan the power supply category, read the Tektronix pages or contact SMK Vietnam.
2230-30-1 questions
Which channel carries the 5 A?
Channel 3 does, at 6 V. Channels 1 and 2 give 30 V and 1.5 A each.
Does the 2230-30-1 have GPIB or RS-232?
The listing names USB only. Ask Lost in HCM if you need another port.
Is the 120 W available on every channel at once?
The listing states 120 W for the whole unit. Check the limits for your own load mix before you plan a test.
