Description
Before you book a system supply, write down three numbers: the voltage, the current and the mains feed. The Keysight DP5748AH DC power supply answers with 80 V, 42 A and a three-phase 380/480 VAC input. That gives 3,360 W from one output. Lost in HCM lists it for rental and sale.
Three numbers that decide the fit
- Voltage: the output reaches 80 V.
- Current: it supplies up to 42 A.
- Mains: it takes three-phase 380/480 VAC.
If your load needs more than 80 V or 42 A, this is the wrong unit. If it fits inside both limits, read on. The product is a compact 1U case, so it also saves rack space.

Reading ripple and response
Noise and ripple reach 80 mV peak-to-peak, and the output responds in 50 ms. Neither figure is a problem for most bench-style converter work. However, a sensitive analog stage may need extra filtering, so check your own limit before you trust any supply. In addition, programming accuracy of 40 mV tells you how closely the voltage follows your command.
Automation hooks
Four digital routes connect the unit to a controller: GPIB, LAN, USB and LXI. Also, analog and resistance control give a hardware alternative. The supply also measures voltage and current, so a test script can log each step. Meanwhile, adjustable slew rate and arbitrary waveform generation support dynamic device profiles. Overvoltage, overcurrent and system protection add a safety layer.
Jobs that suit this supply
For example, teams use this class of source in automated production and qualification racks. It also serves power-device and converter validation, as well as automotive and industrial electronics testing. Finally, a development lab can treat it as plain programmable DC power.
Rent first, decide later
A short rental lets you try the Keysight DP5748AH DC power supply on a real project. If the unit proves its worth, ask about a purchase instead. First confirm that your site has a three-phase 380/480 VAC feed. Then request a quote from Lost in HCM and state your dates. You can also browse power supply listings, visit Keysight or contact SMK Vietnam. Lost in HCM gives the quote.
