Keysight N6743B DC Power Module, 20 V, 5 A, 100 W for N6700 and N6705

Description

Automated stations punish a supply that is slow or fussy to program. The Keysight N6743B DC power module gives one output of up to 20 V and 5 A, inside a 100 W limit. It fits in a single slot of an N6700 or N6705 system. Lost in HCM lists it for rental and sale.

N6743B rating snapshot

Running it from a script

A test script talks to the module over the interface of the host frame. Commands take about 32 ms to process, so build that delay into each step. The 0.2 ms output response then handles the electrical side. Together, these two figures tell you how fast a sequence can run.

Dynamic tests with LIST mode and waveforms

LIST mode stores a series of output settings that the module plays back on its own. Arbitrary waveforms add custom shapes, while the slew rate controls edge speed. Meanwhile, the data logger captures voltage and current as the sequence runs. Therefore these tools let you reproduce a supply event, such as a sag or a ramp, exactly each time.

Typical jobs for the Keysight N6743B DC power module

Most buyers power device-under-test rails with it. Others supply ATE fixture resources, since the module takes script control well. Embedded, automotive and industrial electronics development makes up a large share of use. Finally, production lines verify multi-rail sequencing with it.

Compare it with the N6741B

Both modules share a 100 W limit and a single slot. The N6743B trades current for voltage: it offers 20 V and 5 A, whereas the N6741B offers 5 V and 20 A. So pick the one that matches your rail, and add the other if the frame has a free slot.

What to include in the request

First name the mainframe, the firmware version and the spare slot. Then add the total power budget, the load and sense leads, the connector block and the software you will use. Also mention whether you want the output-disconnect relay option. Lost in HCM then returns a quote that fits your rack. To start, ask Lost in HCM for a Keysight N6743B DC power module quote.

Questions about the N6743B

How does the N6743B differ from the N6741B?

The N6743B favors voltage, and the N6741B favors current. Both are single-slot modules with a 100 W limit.

Will it work in an N6705 analyzer?

Yes, because it is intended for compatible N6700 modular power systems and N6705 DC power analyzers. Check firmware, free slots and the frame power budget first.

Can I buy a used unit?

Lost in HCM can quote new, premium-used or technically equivalent modules, subject to availability, configuration and inspection.
