Description
Not every source runs at low voltage. Some rails sit high, so they need a load with a high voltage limit but modest current. The Keysight N3303A electronic load module accepts up to 240 V at 10 A, with 250 W of sinking power. It plugs into one slot of an N3300A or N3301A mainframe. Lost in HCM lists it for rental and sale.

Why a high voltage limit helps
Because a load must survive the highest voltage your source can present, the limit matters first. The Keysight N3303A electronic load module takes up to 240 V, so it covers sources that a lower-voltage load would not accept. The trade is current, because the input stops at 10 A. At 25 V, then, you reach the 250 W ceiling.
So multiply voltage by current for your own operating point. Leave margin for startup peaks.
Loading and capturing in one step
Constant-current, constant-voltage and constant-resistance modes also let you shape the load. Six current ranges then give fine control when the draw is small. Meanwhile, 16-bit measurements and built-in waveform digitization record how the source answers each change, which helps with transient checks.
Work this module can take on
- Testing multi-output DC power supplies on a production line.
- Validating DC-DC converter and telecom power designs.
- Characterizing batteries, chargers and power components.
- Adding a programmable load channel to an automated rack.
Before delivery
Lost in HCM turns the test requirement into a configuration checklist. First, the team compares module and mainframe serial numbers, slot space, total mainframe power and firmware. It also reviews the current range, the input terminals, the load cables, the remote-sense wiring and the interface. As a result, buyers compare offers that really match, and a missing cable does not delay the work.
Ask for the Keysight N3303A electronic load module
Rent it for a validation project with a fixed end. Otherwise, ask for a purchase quote if the line runs every day. Lost in HCM supplies the module and gives the quote, while SMK Vietnam only shows the listing. Then request a quote from Lost in HCM, open the DC electronic load listings, visit Keysight or contact SMK Vietnam.
N3303A questions
What is the maximum input voltage?
The input accepts up to 240 V. However, current stops at 10 A.
How many mainframe slots does it use?
It uses a single slot in a compatible N3300A or N3301A mainframe.
Is a new unit the only option?
No. Lost in HCM can also quote premium-used and technically equivalent load modules, subject to lifecycle and inspection.
