Description
A new inverter must cope with real grids, not just clean lab mains. The Keysight AC6903H AC power source gives your bench a programmable three-phase supply rated at 3 kVA. Lost in HCM lists it for rental and sale in Vietnam, so you can borrow it for a project or buy it.
What the Keysight AC6903H AC power source delivers
The output reaches 320 Vrms in AC mode and 452 V in DC mode, at frequencies up to 5 kHz. Maximum power is 3000 VA, or 3 kW in DC. Each output carries up to 40 A. Because AC, DC and AC-plus-DC modes all exist, one unit can act as a mains supply or as a DC bus.

| Maximum DC voltage | 452 V |
| Maximum power | 3000 VA / 3 kW DC |
| Maximum current per output | 40 A |
| Maximum frequency | 5 kHz |
| Interfaces | LAN, USB, optional GPIB |
Wiring, waveforms and protection
Single-, two- and three-wire connections suit several mains and inverter layouts. In addition, built-in harmonic analysis, waveform generation and sequencing mean fewer separate instruments on the bench. Protection also matters. The unit offers current, over-voltage and under-voltage protection, plus inhibit and soft-start functions. As a result, your device under test sees a gentle start and a firm cutoff.
Bench jobs that fit a 3 kVA source
Teams use this class of source for three-phase power electronics and inverter validation. Motor-drive, appliance and industrial equipment testing also fit well. Then there is grid disturbance and harmonic immunity simulation, where you dirty the supply on purpose and watch how the product reacts. Renewable-energy and aerospace power-system research round out the list.
The product photo shows the front panel with a color display, a numeric keypad, phase-select buttons and a rotary knob. It may carry a related model marking, so check the label on your unit.
Rent for a project, buy for steady use
Rent when you have a defined project, an urgent replacement or a temporary production peak. Buy when the same tests recur every month, because ownership then makes more sense. Either way, Lost in HCM quotes the exact configuration of your Keysight AC6903H AC power source. State the wiring, voltage, current, power and frequency you need, plus the delivery site and any calibration paperwork you expect.

AC6903H questions
Which wiring modes does it support?
It supports single-, two- and three-wire connections, so you can match the topology of the product you test.
Do the cables and GPIB come with it?
Ask for them by name. Power cabling, connectors, rack or floor placement, commissioning, GPIB and calibration documents all belong in the quote as separate items.
Can I buy it instead of renting?
Yes, Lost in HCM can quote a purchase as well. Configuration and availability decide which offer fits your lab.
