Description
A real battery pack is slow to cycle and hard to repeat. The Keithley 2281S-20-6 battery simulator stands in for the pack, and it also works as a precision DC supply. Lost in HCM lists it for rental and sale, and it arranges service on request.
Headline figures
| Item | Value |
|---|---|
| Outputs | 1 |
| Maximum voltage | 20 V |
| Maximum current | 6 A |

Check your pack voltage and charge current against these limits first. Then ask Lost in HCM to confirm the quoted configuration.
How the Keithley 2281S-20-6 battery simulator replaces a pack
Instead of cycling a real cell, you program the instrument to behave like one. It can hold up to 14 stored models, so one bench can step through several battery profiles in a single session. The front display in the product photo shows state of charge, amp-hours, series resistance and open-circuit voltage side by side. The listing also gives a maximum output resistance of 100 ohm, which matters when you imitate a worn cell with high internal resistance.
Where it earns its place
- Battery-powered product testing, such as handheld tools and wearables
- Charger evaluation without waiting for a pack to drain
- Device characterization in an R&D lab
- Automated test on a production line
Because the output repeats exactly, two engineers can compare results from different days. A drained pack cannot promise that.
Before you wire it up
Confirm the AC line option, channel configuration, control interface, cables, fixture and software support before ordering. Also check polarity, grounding, shielding and protection settings on your device. Then follow the current Keithley manual for interlocks and remote sensing.
Rent or buy the Keithley 2281S-20-6 battery simulator
A short charger-validation project suits a rental. A team that runs the same battery profiles every week may prefer to buy. Either way, request a quote from Lost in HCM with your dates, site and accessories. You can also browse more power supply listings, visit Tektronix for the Keithley range, or contact SMK Vietnam.
2281S-20-6 questions
Is it only a battery simulator?
No. It also works as a precision DC power supply, so it can serve a normal bench task too.
How many outputs does it provide?
One. The listing shows a single output rated 20 V and 6 A.
Which control interface does it use?
The listing does not name one, so ask Lost in HCM to confirm it before you order.
