Question 1

What does this AC power source do?

Accepted Answer

It converts the input mains through an AC-DC-AC power stage to provide adjustable sine-wave AC voltage and frequency for product testing. Select the phase configuration, rated current and capacity to match the equipment under test.

Question 2

Is 400Hz or programmable control standard?

Accepted Answer

The standard specified frequency range is 40-120Hz, covering 50Hz and 60Hz testing. Extended frequency up to 400Hz, remote interfaces and programmable functions require a separately confirmed model and order specification.

Question 3

How do I choose the required capacity?

Accepted Answer

Provide the rated input voltage, phase, running current, starting or inrush current, power factor and test duration of the load. Motors and compressors may require extra capacity; selection is based on the actual starting duty rather than running kW alone.

Question 4

Are input isolation and special voltages included?

Accepted Answer

Input isolation, transformer arrangement, special input voltages and output connection requirements are confirmed by the selected model and order. Do not assume every capacity has the same isolation configuration.

Question 5

How are terminals and installation confirmed?

Accepted Answer

Input, output, neutral and protective-earth terminals follow the wiring drawing supplied with the ordered model. Terminal positions and cabinet layout vary by capacity. Installation and commissioning should follow that drawing and the product manual.

Question 6

What should I confirm before ordering?

Accepted Answer

Confirm capacity, input supply, single- or three-phase output, voltage range, frequency range, load requirements and optional functions. The SKU price applies to the quoted standard configuration. Custom options, shipping and special test requirements are confirmed for the project.

Question 7

Are product photographs identical for every capacity?

Accepted Answer

Photographs show real examples from the product series. Cabinet size, control panel and internal layout depend on the capacity and order configuration. Confirm the selected model drawing when appearance or dimensions are critical.

Question 8

Can this replace a motor speed drive?

Accepted Answer

This product is an adjustable sine-wave AC test power source. It is not specified here as a general-purpose motor speed-control drive. Motor test use requires evaluation of voltage, frequency, current and starting duty.

Question 9

Can the same kVA be delivered at every voltage?

Accepted Answer

Available output is limited by the selected model current rating and operating range. At lower voltage, available kVA may be reduced. Confirm the required voltage and load current together.

Question 10

Can I request a customized test setup?

Accepted Answer

Provide the equipment under test, phase configuration, voltage and frequency points, running and starting current, test duration, and interface requirements. The factory confirms the suitable configuration and project quotation.
