Description
Seventy-five amps change how you build a test station. The Keysight DP5790AL DC power supply carries a nominal rating of 100 V and 75 A. That adds up to 7,500 W from a low-line AC input. Lost in HCM lists it for rental and sale, so you can rent it for a project or buy it for a rack.
Why 75 A changes the setup
At this current, the wiring becomes the weak link. Cables, terminals, fuses and contactors all have to carry the full load without heating. A thin lead can also drop volts before the load sees them, so plan your sense wiring early. Because the output is current-heavy, it also pays to map the discharge path and the emergency shutdown before the first power-up.
Keysight DP5790AL DC power supply ratings
| Item | Listed value |
|---|---|
| Nominal output voltage | 100 V |
| Nominal output current | 75 A |
| Nominal output power | 7,500 W |
| Product family | Keysight DP5700 Series system DC power supply |
| AC input | Low-line variant (AL suffix) |
These figures mark one full-power point, not a window you can stretch both ways. Therefore, read the operating curves and derating in current Keysight documentation before you approve a test plan. Ripple, transient response and protection behavior deserve the same check.
Where a 100 V, high-current source fits
A 100 V ceiling suits lower-voltage DC buses and battery-based work. For example, engineers use a supply like the Keysight DP5790AL DC power supply for DC bus simulation, inverter and converter development, and charging-system research. It also feeds solar, storage and energy-management projects that need repeatable DC stimulus. Production and university labs use it as well, as long as supervision and protection match the power level. If you need more voltage, ask about other DP5700 models.
Check the mains before you book
The AL suffix means the unit expects a low-line AC input. Compare it with your facility voltage, phase, frequency, connector, breaker and wiring. Then check rack space, airflow and weight, since a 7.5 kW unit is not a casual drop-in. In addition, confirm the remote interface, firmware and drivers if a script will drive it.

DP5790AL questions
How should I size cables for 75 A?
Match cables, terminals and fuses to the full rated current. Review them again for every new setup.
What does the AL suffix tell me?
It marks the low-line AC input variant. Check the input requirement against your site supply first.
What should a quote request include?
Send the application, output range, site input power, quantity, delivery city, accessories and project dates.
