Keysight 60504B Load Module, 600 W, 60 V, 120 A, for 6050A and 6051A Mainframes

Description

Low-voltage supplies can push very large current, and testing them takes a load that accepts it. The Keysight 60504B load module accepts up to 120 A at up to 60 V, with a sinking limit of 600 W. Lost in HCM lists it for rental and sale, and Keysight marks the model as obsolete.

Built for heavy current

The 120 A input rating suits sources that deliver heavy current at low voltage. The module needs two slots in a 6050A or 6051A mainframe. So plan your rack layout before you order. Two slots leave less space for other modules, and the extra size is the price of the higher current.

Key figures for the Keysight 60504B load module

• Sinking power tops out at 600 W.
• Input voltage reaches 60 V.
• The input accepts 120 A at most.
• Two mainframe slots are needed.
• Because the lifecycle is obsolete, supply depends on used inventory and a parts review.

Choosing the load mode

First, pick constant current, constant voltage or constant resistance to match the source under test. In constant-current mode, an analog voltage can also program the setpoint from outside. The mainframe handles programming and readback, so a test program can set a value and then read it back.

Planning a move to the N3306A

Keysight names the N3306A as the recommended replacement. Before you migrate, compare current, power, slot use and parts availability. Program changes may follow, so budget time for them. Lost in HCM can tell you what it can supply for either path.

Who uses a high-current load

Battery and power-component characterization needs a load that holds a steady current. Likewise, DC supply and converter verification asks for the same. In addition, teams that keep legacy test systems alive often need spare modules, so a rental can bridge the gap.

Order route

Rent the Keysight 60504B load module for a short qualification job, or buy it to keep a rack alive. For either case, request a quote from Lost in HCM and describe your mainframe, delivery site and schedule. You can also browse other DC electronic loads, read the Keysight website, or contact SMK Vietnam.

Heavy-current load questions

How much current can it take?

Up to 120 A at its input, with a 60 V maximum and a 600 W sinking limit.

Which protections does it include?

Overcurrent, overvoltage, overpower, overtemperature and reverse polarity.

How many mainframe slots does it use?

Two, in a Keysight 6050A or 6051A mainframe.
