Description
The last letter of a DP5741A listing tells you which wall feed to prepare. The Keysight DP5741AL DC power supply pairs with a three-phase 200/240 VAC input and delivers up to 10 V and 340 A. Lost in HCM lists it for rental and sale in Vietnam.
Reading the AH, AL and AS suffixes
| Model | AC input in the listing | Output ratings |
|---|---|---|
| DP5741AH | Three-phase 380/480 VAC | 10 V, 340 A, 3,400 W |
| DP5741AL | Three-phase 200/240 VAC | 10 V, 340 A, 3,400 W |
| DP5741AS | Single-phase 200/240 VAC | 10 V, 340 A, 3,400 W |
The three listings share one set of output ratings. So the suffix mainly tells you which mains feed to prepare. Therefore pick the version that matches your panel, rather than adapting the panel to the supply.
When the 200/240 VAC three-phase version fits
Choose the Keysight DP5741AL DC power supply when your facility offers three-phase power at 200/240 VAC. If your panel offers 380/480 VAC instead, ask about the AH version. Then confirm the connector, the protection and the installation plan, because those details decide the quote.
Key figures
- Voltage programming accuracy: 5 mV
- Noise and ripple: 75 mV peak-to-peak
- Output response time: 30 ms
- Interfaces: GPIB, LAN, USB, LXI and analog/resistance control
An adjustable slew rate and arbitrary waveform generation shape the output, and built-in measurement checks voltage and current. In addition, overvoltage, overcurrent and system protection reduce risk to the device under test.
Where the Keysight DP5741AL DC power supply fits
Also, the compact 1U case suits dense automated racks. For example, the listing names production and qualification racks, power-device and converter validation, automotive and industrial electronics testing, and laboratory development. A short rental covers one campaign, while a purchase suits a station that runs all year.
