Description
Some loads want volts more than amps. The Keysight DP5751AH DC power supply reaches 150 V while it supplies up to 22.5 A, which is 3,375 W from one output. It runs from a three-phase 380/480 VAC input. Lost in HCM lists it for rental and sale in Vietnam.
When 150 V is the point
Higher-voltage work, such as DC bus tests on drives and converters, often needs a source in this range. A power stage can then run near its real operating voltage instead of a scaled-down stand-in. Current stays moderate, so the unit suits a bus that sits at a few tens of amps at most. Check your load’s maximum current against the 22.5 A rating first.

What the signal figures say
Voltage programming accuracy is 75 mV. Noise and ripple reach 120 mV peak-to-peak, and the response time is 50 ms. At a 150 V setting, a ripple of that size is a small fraction of the output. Even so, always compare the figures with the limits of your own design.
Control, measurement and protection
GPIB, LAN, USB and LXI link the supply to a test computer. Analog and resistance control give another route. In addition, the unit measures its own voltage and current. Adjustable slew rate and arbitrary waveform generation let you shape a profile, for example a slow climb to 150 V. Overvoltage, overcurrent and system protection reduce the risk to the load.
Typical work
- Power-device and converter validation
- Automated production and qualification racks
- Automotive and industrial electronics testing
- Laboratory development with programmable DC power
Before you request a quote
Confirm that your site supplies three-phase 380/480 VAC, because this input decides whether the unit can run. Then request a quote from Lost in HCM and say whether you want to rent or buy. The compact 1U case helps in a crowded rack. You can also visit Keysight, the power supplies category or SMK Vietnam. Lost in HCM supplies the Keysight DP5751AH DC power supply and gives the quote.
DP5751AH questions
Is 150 V the maximum output voltage?
Yes. The listing gives a maximum of 150 V, with up to 22.5 A.
Which AC input does the AH version need?
A three-phase 380/480 VAC input.
Can a script read its output?
Yes. Built-in voltage and current measurement lets a script do so.
