Description
Accuracy and ripple tell you more about a supply than its power rating does. The Keysight DP5723A DC power supply lists 15 mV programming accuracy and 50 mV peak-to-peak ripple on one output of up to 30 V and 50 A. Lost in HCM lists it for rental and sale in Vietnam.
Reading accuracy and ripple together
Programming accuracy shows how closely the output matches the value you set, while ripple shows how much noise rides on top. The Keysight DP5723A DC power supply lists both, so you can check them before you book. Suppose your board tolerates 100 mV of noise on a rail. Then 50 mV of ripple uses half that margin, so the figure is worth a look.

Response and protection
The output responds in 20 ms, and an adjustable slew rate also lets a script soften each transition. Overvoltage, overcurrent and system protection guard the device under test as well. Because the supply measures voltage and current itself, a test log needs no extra meter.
Where 30 V and 50 A fit
The listing names automated production and qualification racks, power-device and converter validation, automotive and industrial electronics testing, and laboratory development. Because these jobs repeat, a stable programmable source saves setup time. A half-rack, 1U case also suits a dense station, so it can share a row with other instruments.
Compare the Keysight DP5723A DC power supply before you commit
However, a similar headline rating does not prove that two supplies behave alike. So compare ripple, response, accuracy conditions and interfaces side by side. Then list each difference in your quote request. When you are ready, request a quote from Lost in HCM and ask which calibration documents come with the unit. The power supply listings, the Keysight site and contact SMK Vietnam can help you narrow the choice.
DP5723A questions
How should I compare it with another supply?
Look at ripple, response time, accuracy conditions and interfaces together. A matching power rating alone does not make two supplies equivalent.
Which interfaces can an automated rack use?
The listing gives GPIB, LAN, USB and analog control. It does not mention LXI for this model.
Which documents should I request?
Ask Lost in HCM whether the quote includes calibration documents, and which accessories and options the offered unit carries.
