Description
Power brings a price in rack space. The Keysight N3305A electronic load module sinks up to 500 W. Its limits are 150 V and 60 A, and it occupies two slots of an N3300A or N3301A mainframe. Teams should plan the frame around it. Lost in HCM lists it for rental and sale, and it arranges service on request.

Doing the slot math
This module takes two slots, so it limits how many others fit beside it. Count the slots you have, then add the power every module will draw from the frame. Lost in HCM also checks the total mainframe power. A large module can use a good share of it.
As a result, the frame decides the quote as much as the module does.
A wide window for high-power sources
Few modules combine 150 V and 60 A limits. Even so, the 500 W ceiling applies at every point. At 150 V you can draw a little over 3 A. At 60 A the voltage can reach only about 8.3 V. Check your own operating point against that curve, then leave margin for peaks.
Characterizing power sources
Constant-current, constant-voltage and constant-resistance modes load a source in different ways. Six current ranges, 16-bit readings and waveform digitization then show how it behaves. The Keysight N3305A electronic load module suits several jobs. Examples include multi-output supply tests and DC-DC converter checks. It also fits telecom power validation, battery studies and automated systems.
Handover checklist
- Module and mainframe serial numbers.
- Free slot space and total frame power.
- Firmware, current range and input terminals.
- Load cables, remote-sense wiring and the control interface.
Request the Keysight N3305A electronic load module
Lost in HCM quotes a rental with a compatible mainframe. It can also price new, premium-used or equivalent modules for a purchase. It supplies the equipment, while SMK Vietnam only shows the listing. Send your dates, site and slot plan. Then request a quote from Lost in HCM, browse the DC electronic load listings, visit Keysight or contact SMK Vietnam.
N3305A questions
How many slots does the N3305A need?
It needs two slots in an N3300A or N3301A mainframe.
Can it sink 500 W at any voltage?
No. The 500 W limit works alongside the 150 V and 60 A limits, so only some pairs reach full power.
What should I check before ordering?
Check free slot space, total mainframe power, firmware, terminals, load cables and the control interface.
