Description
High voltage does not have to mean high power. The Keithley 2260B-250-4 power supply reaches 250 V on one programmable output, yet its rating stops at 360 W. Lost in HCM lists it for rental and sale, so a team can borrow it for one project or buy it for a permanent station.
250 V on a 360 W budget
The maximum current is 4.5 A. However, 250 V times 4.5 A is 1,125 W, far above the rating. So the supply cannot hold both extremes at once. Size your load against the 360 W figure, then check that voltage and current each stay inside their own limits. For example, a load at the full 250 V can draw about 1.4 A.
Keithley 2260B-250-4 power supply at a glance
| Rating | Listed value |
|---|---|
| Outputs | 1 |
| Maximum voltage | 250 V |
| Maximum current | 4.5 A |
| Maximum power | 360 W |
| Connectivity | USB and LAN |
The listing names USB and LAN. It does not name analog control, while the 2260B-30-36 and 2260B-80-13 listings add it. Therefore, plan on software control for this model unless Lost in HCM confirms otherwise.
Control and wiring
A program on a PC can drive the output over USB or LAN. LAN also suits a rack, because one network cable reaches the instrument without a bench PC. Keithley’s generic wiring note also mentions remote sense and other control options as equipped, so ask which ones your unit carries.
Where a 250 V source helps
The listing points to controlled DC power delivery, device characterization, production testing, life testing and power-system development. In practice, a 250 V ceiling suits converter inputs and small DC-bus experiments at low current. Life testing also fits, because a script can hold a setting through a long run. Then a technician only reads the log.
Order the Keithley 2260B-250-4 power supply
Confirm the AC line option, the output leads, the rack arrangement and the software support first. Then request a quote from Lost in HCM and say whether you want to rent or buy. You can also browse more power supply listings, read about the brand at Tektronix, or contact SMK Vietnam with order questions.
250-4 questions
Can it deliver 250 V and 4.5 A together?
No. That pairing would need 1,125 W, and the listing gives 360 W. Plan the load around the power rating.
Does it include analog control?
The listing names USB and LAN only. Ask Lost in HCM before you plan a hardwired control signal.
Is this listing for rental or for sale?
Both. Lost in HCM supplies the unit and gives the quote, while SMK Vietnam only shows the listing.
