Description
Older test stations often talk to their instruments over a serial line. The Keithley 2230-30-3 power supply speaks both USB and RS-232, so it fits a modern laptop and a legacy controller alike. Lost in HCM lists it for rental and sale, and arranges service on request.
Serial control for stations that never retired
Plenty of factory fixtures still run on a PC with a serial port, so the Keithley 2230-30-3 power supply keeps them useful. With this model, you can keep that fixture and add a three-rail supply. The listing names USB and RS-232. Therefore, a new station can use USB while an old one keeps its serial cable. Ask Lost in HCM about the cable and driver you need.
Three channels and 195 W in one case
- Channels 1 and 2: 30 V and 3 A each.
- Channel 3: 5 V and 3 A.
- Maximum power: 195 W for the unit.
Because every channel offers 3 A, small drive stages, relay boards and sensor modules sit comfortably inside the range. The 5 V channel then covers a logic supply. Check your peak current first, however, since each output stops at its stated limit. In addition, plan your total draw, because the unit maximum is 195 W.
Where it earns its bench space
Design verification, research and automated test all need repeatable power, so the Keithley 2230-30-3 power supply earns its place in each. A script can set each channel, run a sequence and log the result. Because the outputs stay isolated, one faulty circuit does not pull the others down with it. Read the Keithley manual on grounding and safe operating limits before first use. Then confirm the AC line option, because that choice affects how the unit connects to your mains.
Ordering the Keithley 2230-30-3 power supply
Rent it for a validation run, or buy it for a station that runs all year. In both cases, request a quote from Lost in HCM with your dates and accessory list. More models appear in the power supply listings. For brand details, visit Tektronix, or contact SMK Vietnam.
2230-30-3 questions
Can it connect to a PC with only a serial port?
The listing names RS-232 beside USB, so a serial link is possible. Confirm the cable with Lost in HCM.
Which channel is the 5 V one?
Channel 3 is the 5 V output, and it delivers up to 3 A. Channels 1 and 2 each deliver up to 30 V at 3 A.
Do I buy or rent for a two-month project?
Rent if the work ends soon. Buy if the same station keeps running. Lost in HCM quotes both.
