Description
A prototype costs far more than the supply that powers it. That is why protection matters first. The Keysight DP5751AL DC power supply offers overvoltage, overcurrent and system protection on an output of up to 150 V and 22.5 A. The rating is 3,375 W, from a three-phase 200/240 VAC input. Lost in HCM lists it for rental and sale.
Protect the device under test first
Set limits before you connect the load, not after the first surprise. Pick an overvoltage level slightly above your highest planned setting. Then choose an overcurrent level that matches what the device may draw in a fault. These steps cost a few minutes, yet they can save a board or a module.

Treat the figures for the Keysight DP5751AL DC power supply as a starting point. Installed options and the formal quote decide the delivered configuration.
Measuring while you protect
The supply reads back its own voltage and current, so a script can compare them with expected values on every step. Moreover, adjustable slew rate and arbitrary waveform generation soften the start of a test. A gentle ramp is kinder to a sensitive load than a hard step. GPIB, LAN, USB and LXI carry the commands, and analog and resistance control remain available.
Where the Keysight DP5751AL DC power supply gets used
Engineers choose it for power-device and converter validation, automated production and qualification racks, and automotive and industrial electronics testing. Laboratory development with programmable DC power is another case. So the 1U case keeps the footprint small.
Rent it, then decide
A rental lets you prove the setup before you spend on a unit. First confirm that your facility offers three-phase 200/240 VAC. Next, request a quote from Lost in HCM and share your dates. Also, related pages include the power supplies category, the Keysight site and the SMK Vietnam contact page. Lost in HCM supplies the unit and gives the quote.
