Benchtop DC electronic load for R&D

April 25, 2018 // By Nick Flaherty
Chroma Systems Solutions has launched a benchtop programmable DC electronic load for 350W applications in research and development labs.

The 63000 is targeted for testing numerous types of components and devices including switching power supplies, AC-DC power supplies, DC-DC converters, adapters, batteries and chargers. 

User Defined Waveforms allow researchers to simulate actual current profiles and waveforms by uploading captured waveform data through the softpanel. Each load can store up to 10 sets of waveforms containing up to 1.5 million data points. It also provides voltage peak measurements eliminating the need for an oscilloscope. In addition to constant current, constant voltage, constant power and constant resistance modes, the 63000 is equipped with CZ mode for turn on capacitive load simulation. CZ mode simulates the actual inductance, impedance and capacitance for loading, making the load current closer to real conditions.

The built-in dynamic load settings test the transient response of a power supply. These loads have 2 separate current settings each capable of different slew rates and dwell time settings. Dwell times range from 50 micro seconds to 99.9 seconds, slew rates up to 3 amps per micro second with a 20 micro second minimum, and returns measurements for the voltage plus and minus peak. In addition, the 63000 provides three current ranges with very high measurement accuracy making them applicable for US EnergyStar compliance testing.

Chroma’s programmable power supplies, electronic loads, meters, hipot testers and automated testing systems are used in aerospace, military, commercial, medical, battery, marine, and regulatory testing as well as green energy markets including solar, electric vehicle and LED systems.

The initial release of the 63000 includes models up to 350 watts, 150 volts and 60 amps with USB, Ethernet and GBIP support, a large LCD display, user-defined hot keys, and all necessary protections built-in.
