Description
A production line can run for years, yet a new product may need a supply for only a few months. The Keysight DP5728A DC power supply offers up to 80 V and 19 A on one output, rated at 1,520 W. Lost in HCM lists it for rental and sale in Vietnam.
Eighty volts for production and qualification racks
The listing names automated production and qualification racks first, then power-device and converter validation, automotive and industrial electronics testing, and laboratory development. At 80 V and 19 A, the unit covers higher-voltage devices while the current stays modest. A 1U half-rack case also keeps the station compact.
Check ripple and response against your device
The Keysight DP5728A DC power supply lists 40 mV voltage programming accuracy and 75 mV peak-to-peak ripple. However, your own device tolerance matters more than either figure. Output response time is 50 ms, which is longer than the 20 ms to 30 ms in the DP5722A to DP5726A listings. So a fast load step may need extra margin in your test timing.

Rent or buy: a quick guide
- Rent for a defined project, an urgent replacement or a temporary rise in production.
- Buy when the supply will run in the same rack for years.
- Either way, ask for the configuration, accessories and calibration documents in writing.
Plan the Keysight DP5728A DC power supply handover
Request a quote from Lost in HCM with your delivery site, dates and AC input details. Agree on cables and test files before the unit ships, so the station runs on day one. For alternatives, see the power supply listings, the Keysight site or contact SMK Vietnam.
DP5728A questions
When does buying beat renting?
Buying makes sense when the same rack needs the supply every week. A rental fits a defined project or a short production peak.
Can it step in as an urgent replacement?
The listing names urgent replacement as a rental reason. Ask Lost in HCM what it can supply and when, because availability needs checking.
What are the ripple and accuracy figures?
Voltage programming accuracy is 40 mV, and noise and ripple are 75 mV peak-to-peak. Compare both with your device limits.
