Description
Not every lab has three-phase outlets. The Keysight DP5742AS DC power supply runs from single-phase 200/240 VAC and still reaches 20 V, 170 A and 3,400 W. Lost in HCM lists it for rental and sale in Vietnam, so a team without a three-phase panel can still request it.
A single-phase feed for the Keysight DP5742AS DC power supply
The AS suffix marks the single-phase version in this family. A 3.4 kW supply is a large load for one phase, so plan a dedicated circuit. Check the breaker rating, the plug and the cable run with your facility team. As a result, you avoid a tripped breaker in the middle of a test.

What it does on a smaller bench
A development lab can use the Keysight DP5742AS DC power supply as programmable DC power for low-voltage, high-current work. Meanwhile, a production team can mount the 1U case in an automated qualification rack. The listing also points to power-device and converter validation and to automotive and industrial electronics testing.
With adjustable slew rate and arbitrary waveforms, a script can change the output smoothly or in steps. Built-in measurement reads voltage and current, so a script can log each step. Overvoltage and overcurrent protection watch over the device under test.
Picking among the DP5742 suffixes
All three suffixes share the same 20 V and 170 A output. The AH takes three-phase 380/480 VAC, the AL takes three-phase 200/240 VAC, and this AS takes single-phase 200/240 VAC. So the choice depends on your mains, not on the output.

DP5742AS questions
Does a lab without three-phase power need an upgrade?
This version takes single-phase 200/240 VAC, so it may avoid one. Still, ask an electrician to confirm the circuit.
How fast does the output respond?
The listing gives 30 ms, so leave a short wait between test steps.
Should I rent or buy this supply?
Rent for a fixed project. Buy if the same source will serve a rack for years.
