Description
Small supplies, chargers and converter stages rarely need a heavy load, so a modest module can serve. The Keysight 60501B load module sinks up to 150 W at up to 60 V and 30 A, and it takes one slot in a 6050A or 6051A mainframe. Lost in HCM lists this obsolete model for rental and sale.
Sizing a 150 W module
The three ratings apply together, not one at a time. Sixty volts at 30 A would far exceed 150 W, so the power limit decides what the module can absorb when voltage and current are both high. Match it to the supply you test, then leave some margin. A 6051A mainframe can carry up to two of these modules, which suits a test of a two-output supply.
Ratings of the Keysight 60501B load module
| Item | Value |
|---|---|
| Inputs | 1 |
| Maximum input voltage | 60 V |
| Maximum input current | 30 A |
| Maximum sinking power | 150 W |
| Mainframe slots required | 1 |
| Compatible mainframes | Keysight 6050A and 6051A |
| Operating modes | Constant current, voltage and resistance |
| Recommended replacement | N3302A |
Modes, control and protection
The module runs in constant-current, constant-voltage and constant-resistance modes. In constant-current mode, an analog voltage can also set the load from outside. The mainframe then programs the module and reads measurements back, so a rack can automate the work. Protection also covers overcurrent, overvoltage, overpower, overtemperature and reverse polarity.
Typical jobs in a legacy rack
- Maintaining legacy automated test equipment.
- Verifying DC power supplies and converters.
- Characterizing batteries and power components.
Obsolete model, replacement path
Keysight also lists the 60501B as obsolete. Supply therefore depends on used inventory and a parts review. For a fresh build, Keysight names the N3302A, so check that your mainframe is an N3300A or N3301A.
Asking for a quote
Rental of the Keysight 60501B load module depends on verified module and mainframe inventory, functional testing and calibration status. So name your mainframe and the number of modules first. Then request a quote from Lost in HCM with the cable needs and delivery site. You can also see other DC electronic loads, check the Keysight website or contact SMK Vietnam.
60501B in brief
Which mainframes take the 60501B?
The Keysight 6050A and 6051A. It plugs into a slot and does not run alone.
How many fit in a 6051A?
The 6051A listing allows up to two 60501B modules.
What replaces it?
Keysight names the N3302A. It needs an N3300A or N3301A mainframe, so plan the whole migration.
