Specifications, setup and FAQ
Rohde & Schwarz NGP804 is a 4-channel DC power supply with up to 800 W total output. Four 32 V channels suit multi-rail benches that need higher current on each output. Use this guide to compare its capabilities and prepare a rental, repair or purchase enquiry in Vietnam.
NGP804 specifications at a glance
| Model | NGP804 |
|---|---|
| Manufacturer | Rohde & Schwarz |
| Manufacturer order number | 5601.4007.02 |
| Output channels | 4 |
| Total output power | 800 W maximum |
| Voltage per channel | 0 V to 32 V |
| Maximum output current | 20 A per channel |
| Maximum channel power | 200 W per channel |
For example, a 32 V output at its 200 W channel limit can supply 6.25 A. The 20 A headline current therefore does not apply at 32 V. Select each operating point within the channel power envelope.
Choose the right NGP804 configuration
USB and LAN interfaces are standard. Confirm any optional interface required by the test system. The QuickArb function and data logging support repeatable stimulus and measurement workflows.
Start with a list of the supply rails your device needs. Record the normal voltage, steady current and expected startup current for each rail. Then compare the combined demand with the available power. Leave room for the test conditions you intend to explore, instead of selecting a supply only from one headline rating.
For development work, independent channels can help separate power domains. For a production fixture, also consider connection time, repeatability and how the operator will save the result. If you need an automated sequence, check the actual interface, command support and software environment before committing to a setup.

This is a functional connection guide, not an internal circuit diagram or a service schematic. DUT means device under test. Follow the manufacturer’s operating manual for terminal assignments, grounding, remote sensing and any series or parallel connection. Choose leads and fixtures suitable for the current and operating conditions.
Plan a repeatable bench test
- Define the voltage range, current limit and pass criteria before connecting the device.
- Check polarity and connections with the outputs disabled.
- Set the required protection levels for the device and the intended test.
- Enable the output using the documented procedure, then observe the voltage and current.
- Record settings, operating conditions and unexpected behavior with the test result.
Keep the instrument model and serial number with your records. Include the fixture, cable arrangement and firmware when these affect reproducibility. A result is easier to compare when the next engineer can recreate the same conditions. For formal verification, specify the required calibration evidence and measurement uncertainty in advance.
Rental, repair and purchase enquiries in Vietnam
For a NGP804 rental enquiry, provide the project dates, delivery location, required interfaces and accessories. Describe the load and any startup or transient behavior that matters to the test. This helps the team assess whether the proposed configuration suits the work and confirm availability before a booking.
For purchase, request a quotation that identifies the exact model, condition, included accessories, warranty terms and calibration documents. For repair, describe the symptoms and any error messages. Avoid treating a quotation request as confirmation of stock, delivery or repair feasibility; these details depend on the specific equipment offered and the agreed scope.

NGP804 FAQ
How many outputs does the NGP804 have?
The NGP804 has 4 output channels. Voltage ranges: 0 V to 32 V. The instrument has a maximum combined output power of 800 W.
Can the NGP804 deliver maximum voltage and current together?
No. The output must remain within its power limits: 200 W per channel, with 800 W total for the instrument. Calculate voltage multiplied by current for each intended load.
Can I request a NGP804 rental in Vietnam?
Send the required dates, delivery location, channel requirements and documentation needs to Lost in HCM. Rental availability and the supplied configuration must be confirmed in a quotation.
What should I provide for a NGP804 repair enquiry?
Provide the serial number, fault description, error messages and photographs. Repair feasibility, parts, cost and turnaround are confirmed after assessment.
What is the manufacturer order number for NGP804?
The manufacturer lists order number 5601.4007.02. Optional interfaces, rack accessories and other additions must be specified separately.
