Description
Higher-voltage supplies and converters need a load with voltage headroom more than raw current. The Keysight 6063B DC electronic load accepts up to 240 V and 10 A at one input, inside a 250 W limit. Lost in HCM lists it for rental and sale. Keysight marks this model obsolete, so supply depends on verified used units.
Voltage headroom comes first
Compare this load with a low-voltage, high-current model and the difference is clear. Here the voltage limit is generous while the current limit is modest. Still, 240 V and 10 A cannot occur together, because the 250 W sinking limit caps what the input absorbs. Plan your test point inside that ceiling.
Specifications of the Keysight 6063B DC electronic load
The single input takes up to 240 V and 10 A, with a 250 W sinking limit. Current programming accuracy is 0.15% + 10 mA, while voltage programming accuracy is 0.12% + 120 mV. The load works in constant current, constant voltage and constant resistance modes. Built-in GPIB with SCPI commands handles remote control, so scripts can drive it directly.
Dynamic tests and built-in protection
The load includes a pulse generator, so you can apply programmable steps to a source and watch its response. Voltage and current readback are built in, which helps scripted measurements. Five protection types stand ready: overvoltage, overcurrent, overpower, overtemperature and reverse polarity. Front-panel controls also support single-channel bench work.
Where a 6063B fits in a legacy rack
Many test stations keep the same instrument for years because the program depends on it. The Keysight 6063B DC electronic load suits that situation. It also serves power-supply regulation checks and the evaluation of DC components, such as converters and batteries.
Moving to the N3300 platform
Keysight lists the N3301A mainframe with an N3303A module as the recommended substitute. Compare test limits and software compatibility before you move away from the Keysight 6063B DC electronic load. Meanwhile, a rental keeps today’s station productive.
