Description
Testing a multi-output power supply means loading every rail at once, and that takes a chassis rather than a single box. The Keysight 6050A load mainframe is that chassis, with six slots for DC load modules. Lost in HCM lists it for rental and sale, but Keysight marks the model obsolete, so supply depends on used stock.
Six slots and one GPIB address
The mainframe handles up to 1,800 W in total across its six slots. A single GPIB address controls and reads every installed module, so a test program stays simple. The modules then set the operating modes: constant current, constant voltage and constant resistance.
Which modules fit
| Item | Value |
|---|---|
| Slots | 6 |
| Maximum total power | 1,800 W |
| Supported modules | 60501B, 60502B, 60503B, 60504B, 60507B |
| Capacity | Six 60501B, 60502B or 60503B modules, or three 60504B or 60507B modules |
| Remote control | One GPIB address |
Modules are separate parts, so the quote must list exactly which ones come in the chassis.
What the Keysight 6050A load mainframe can do
- Install modules yourself to mix voltage, current and power ratings.
- Generate pulses for programmable dynamic loading.
- Protect against overcurrent, overvoltage, overpower, overtemperature and reverse polarity.
Rack jobs it still handles
Teams keep the Keysight 6050A load mainframe for maintaining legacy automated test equipment. It also verifies multi-output power supplies, and it loads DC-DC converters and telecom power gear. Because it holds several modules, one chassis can load several outputs together.
Obsolete, so plan the replacement
Keysight names the N3300A as the replacement mainframe. If you migrate, check modules, commands, cables and rack space. Meanwhile, a rental can keep an existing station running while you plan, because a used unit lets you keep the station as it is.
Confirm the setup before delivery
Offers vary by serial number, so check a few items early. Ask about the module list, terminals, cables, remote-sense wiring, firmware and GPIB compatibility. Missing cables or modules can cause delays, therefore settle them in writing.
Request a 6050A quote
Tell Lost in HCM the module mix you need, your delivery site and any calibration paperwork you expect. That way the quote names the Keysight 6050A load mainframe together with its module mix. Then request a quote from Lost in HCM. You can also see other DC electronic loads, read about the brand at keysight.com, or contact SMK Vietnam.
6050A questions
How many modules can it hold?
It takes up to six 60501B, 60502B or 60503B modules, or up to three 60504B or 60507B modules.
Does each module need its own GPIB address?
No. One GPIB address controls and reads all installed modules.
What replaces it?
Keysight identifies the N3300A as the replacement mainframe. Confirm module, command, cable and rack migration needs first.
