Description
A converter that looks fine at light load can behave differently once it carries real current. The Keysight N3307A load module gives you a programmable sink for that test, with up to 150 V, 30 A and 250 W on one input. It takes a single slot in an N3300A or N3301A mainframe. Lost in HCM lists it for rental and sale, so you can borrow it for a project or buy it for a permanent rack.
What the N3307A can sink
| Inputs | 1 |
|---|---|
| Maximum input voltage | 150 V |
| Maximum input current | 30 A |
| Maximum sinking power | 250 W |
| Mainframe slots required | 1 |
| Compatible mainframes | Keysight N3300A and N3301A |
| Operating modes | Constant current, voltage and resistance |
| Measurement | 16-bit voltage, current and power |
| Acquisition | Built-in waveform digitization |
Three modes for three kinds of source
Constant current suits a supply or a battery pack, because you pull a fixed amount and watch the voltage. Voltage mode holds a rail steady, so you can see how much the source can push. Resistance mode acts like a passive load, which gives a converter a realistic step as its input changes. In addition, six current ranges let you load the input gently or heavily and still read small currents.
Seeing a transient with the Keysight N3307A load module
The module digitizes waveforms on its own, and its 16-bit readings cover voltage, current and power. Therefore you can watch how a source reacts to a sudden load step. A team can then compare a design change against the last revision. However, the result still depends on the setup, so keep the load and sense leads short and tidy.
Where it earns its slot
- Testing high-voltage DC power supplies up to 150 V.
- Validating DC-DC converters and telecom power gear.
- Characterizing batteries, chargers and power components.
- Building automated multichannel load systems in a rack.
Check the frame before you book
The Keysight N3307A load module does nothing alone. First confirm that your mainframe is an N3300A or N3301A and that it has a free slot. Then check the total power, the firmware and the interface you plan to use. Also list the cables, the remote-sense wiring and any calibration papers you need. As a result, Lost in HCM can match your request to a complete, working offer.
Rent or buy through Lost in HCM
SMK Vietnam only shows this listing, while Lost in HCM supplies the hardware and gives the quote. A short rental fits a converter validation or a production overflow. A purchase suits a rack that runs every week. To order the Keysight N3307A load module, request a quote from Lost in HCM with your voltage, current, mainframe and dates. You can also browse more DC electronic loads, read about the maker on the Keysight website or contact SMK Vietnam.
N3307A questions
Can the N3307A run without a mainframe?
No. It plugs into a Keysight N3300A or N3301A and uses one slot, so the frame supplies control and power.
Which load modes does it offer?
It runs in constant current, constant voltage and constant resistance modes.
Can I buy a used N3307A?
Lost in HCM can quote new, premium-used or equivalent modules, subject to availability and inspection.
