Description
A test rack built around a 6050A or 6051A mainframe still needs working load modules. The Keysight 60503B load module fits one slot in either mainframe and accepts up to 240 V and 10 A. Lost in HCM lists it for rental and sale, although the model is obsolete.
High voltage in a single slot
This module takes just one mainframe slot. It sinks up to 250 W, so it suits sources of modest current. Its 240 V input limit also gives room for supplies with a higher output voltage. However, the 10 A limit rules out heavy-current work.
Limits of the Keysight 60503B load module
| Item | Value |
|---|---|
| Maximum input voltage | 240 V |
| Maximum input current | 10 A |
| Maximum sinking power | 250 W |
| Mainframe slots | 1 |
| Compatible mainframes | Keysight 6050A and 6051A |
| Operating modes | Constant current, voltage and resistance |
| Recommended replacement | N3303A |
Keeping a legacy rack running
Legacy automated test equipment stays useful only while each module can be replaced. This load works in constant-current, constant-voltage and constant-resistance modes. An analog voltage input lets an outside signal set the current. In addition, protection covers overcurrent, overvoltage, overpower, overtemperature and reverse polarity.
Typical jobs
- Maintaining legacy automated test equipment.
- Verifying DC power supplies and converters.
- Characterizing batteries and power components.
Before you order
Name the mainframe model, because the module fits only 6050A and 6051A units. Say how many modules your rack needs. Also ask for the delivered configuration and any calibration paperwork to appear in the quote, so nothing surprises you on arrival.
Rent, buy or plan the move to a new load
Supply of the Keysight 60503B load module follows used inventory and a parts review. If you plan to leave the 6050-series platform, Keysight names the N3303A as the replacement. Either way, request a quote from Lost in HCM and state the mainframe, the delivery site and the period you need. You can also compare DC electronic loads, visit the Keysight website, or contact SMK Vietnam.
60503B questions
Is the 60503B still in production?
No. Keysight lists it as obsolete, so supply depends on used inventory and a parts review.
Which mainframes accept it?
The Keysight 6050A and 6051A. It is a plug-in module, not a stand-alone load.
Can an outside signal set the current?
Yes, in constant-current mode, through an analog voltage input.
