# Rohde & Schwarz NGP824 800 W Four-Channel DC Power Supply (4 × 64 V/10 A) # Rohde & Schwarz NGP824 800 W Four-Channel DC Power Supply (4 × 64 V/10 A) ## Key Features At A Glance - Five-model series: two- or four-channel DC supplies at 400 W or 800 W total, max 200 W per output - FlexPower delivers variable voltage/current combinations within the 200 W-per-output power envelope - Galvanically isolated, floating outputs wire in series or parallel for up to 250 V or 80 A across the series - 5-inch 800 x 480 WVGA touch display with real-time per-channel statistics - USB and LAN standard; optional WLAN, IEEE-488 (GPIB), digital trigger I/O, and analog input - Protection suite: OCP electronic fuse with FuseLink, OVP, OPP, and overtemperature protection - QuickArb arbitrary sequencing, EasyRamp inrush control, output delay, and timestamped CSV data logging - Four-wire remote sensing and built-in V, I, power and energy measurement on every output The Rohde & Schwarz NGP800 is a series of bench and system DC power supplies built around a quad-core architecture that places up to four independent 200 W outputs in a single instrument. The series comprises five models rated at either 400 W or 800 W of total power, with two or four galvanically isolated, floating outputs. Each output can supply up to 64 V or up to 20 A, and the FlexPower concept lets you generate variable voltage and current combinations at any operating point within the 200 W-per-output limit, rather than being confined to a single fixed range. The series is designed for both manual bench use and automated test systems. Standard USB and LAN interfaces, together with an optional wireless LAN interface, IEEE-488 (GPIB), a digital trigger I/O and an analog input, make the supplies suitable for the bench or for integration into an automated test rack. Because each of the up to four outputs is completely independent and floating, a single instrument can power up to four devices under test simultaneously, and a synchronous output button switches all channels on or off together, which matters for circuits that can be damaged if one voltage rail is present without another. ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Holding our own stock lets us match the right instrument and condition to your application and get it on its way quickly. ## Brand Heritage Rohde & Schwarz was founded more than 80 years ago and remains an independent, privately held company headquartered in Munich, Germany. It has operated under the Rohde & Schwarz name throughout its history, with no major corporate rebranding or acquisition changing the brand. ## Compare Other Models in This Series The R&S NGP800 series comprises five models that share one architecture: up to four independent 200 W outputs in a single instrument. Two-channel models are rated at 400 W total and four-channel models at 800 W total, with each output galvanically isolated and floating so it can be wired in series or parallel with its siblings. Every model in the series shares the same 5-inch touchscreen operation, FlexPower variable-range outputs, programmable functions such as EasyRamp and QuickArb, the full OCP, OVP, OPP and OTP protection suite, and standard USB and LAN connectivity. The models differ in channel count and in the voltage and current rating of each output, which in turn sets the maximum series voltage and parallel current each model can reach. Each new model below is its own dedicated product page with condition-matched pricing. Select the model that fits your channel count and voltage/current requirement, then choose the new listing that matches your budget and lead-time needs. The five models split first by channel count: the NGP802 and NGP822 are two-channel, 400 W supplies, while the NGP804, NGP824 and NGP814 are four-channel, 800 W supplies. They then differ by per-channel rating, with the NGP802 and NGP804 providing 0 V to 32 V at up to 20 A on every channel, the NGP822 and NGP824 providing 0 V to 64 V at up to 10 A, and the NGP814 combining two 32 V/20 A channels with two 64 V/10 A channels. These rating differences set each model's series and parallel limits, as shown in the comparison table that follows: maximum series voltage ranges from 64 V on the NGP802 up to 250 V on the NGP824, and maximum parallel current reaches up to 80 A on the NGP804. Choose the configuration whose native channel ranges and combined series/parallel capability match your application.
