Keysight N3300A – 1800 Watt DC Electronic Load Mainframe (Modules Sold Separately)

• DC electronic load mainframe
• ***Mainframe only – modules sold separately***
• Modules are required for operation
• 1800 watts total maximum power
• 6 slots – full rack width

Today’s high volume manufacturing requires optimization of test system throughput, to maximize production volume without increasing floorspace. The N3300 Series electronic loads can help you in a number of ways to achieve this goal.

Design a system to test a variety of products

This series consists of 2 mainframes and 6 modules. Any assortment of the 6 different modules can be configured into these mainframes, up to the slot capacity. The electronic load can be configured to supply exactly what you need now, and this modular design also allows for easy future reconfiguration.

Modules

Please see page 5 of this document for detailed information on current and low voltage operation ratings for each module.

Control measurement speed vs. accuracy

Decrease the number of measurement samples to achieve greater measurement speed, or increase the number of samples to achieve higher measurement accuracy. You can optimize your measurements for each test.

Control rising and falling slew rates separately

Reduce rate of loading change when necessary for DUT stability or to simulate real life conditions, but otherwise change load values at maximum rate.

Test low voltage power supplies:

The N3300 Series electronic loads operate with full stability down to zero volts. Many other electronic loads available today have been found to become unstable in the operating region below one volt. When designing power supply test platforms, the trend towards lower voltage requirements should be taken into account. Refer to the specification and supplemental characteristic tables for details of lower voltage operating characteristics.

Test high current power supplies:

Electronic load modules can be operated in parallel to provide additional current sinking capability.

Control the electronic load how you want to – GPIB, RS232, and manual use of the front panel all provide complete control of these electronic loads. There are also analog programming and monitoring ports for those applications that utilize nonstandard interfaces, require custom waveforms, or utilize process control signals. Custom waveforms can also be created by downloading a “List” of load parameters. In addition, there is a built-in transient generator, which operates in all modes.

Measure with all load modules simultaneously

Testing multiple output DC power supplies and DC to DC converters can be very time consuming if each output must be tested sequentially. If measurements are being made through a MUX using one DMM, this is what will happen. Using the built-in measurement capabilities of the N3300 electronic loads, all outputs can be measured simultaneously. Alternatively, multiple single output power sources can be tested simultaneously.

Measure voltage and current simultaneously

The N3300 measurement system has individual but linked current and voltage measurement systems. This means that voltage and current measurements are taken exactly simultaneously, which gives a true picture of the power supply under the test’s output at a particular moment in time. Some other electronic loads which feature internal measurement systems actually take current and voltage measurements sequentially and therefore do not give as accurate a picture of momentary power.
