Compact High Power Programmable DC Loads

These loads can be synchronously paralleled up to 480kW and dynamically synchronized for generating complex multi-channel transient profiles.

Chroma Systems Solutions, Inc. announces the release of a new series of high power DC loads designed for testing a wide range of power conversion products including AC/DC and server power supplies, DC/DC converters, EV batteries, automotive charging stations, and other power electronics components. These loads can be synchronously paralleled up to 480kW and dynamically synchronized for generating complex multi-channel transient profiles. The 300% peak overpower capability provides extra headroom for fault condition simulations in automotive batteries, and fuel cells.

Advantages of the 63200A series include ultra-high density power ([email protected]), built in digital microprocessors, master/slave parallel control, sine wave dynamic loading, and an industry leading measurement accuracy achieving 0.015%+0.015%F.S., 0.04%+0.04%F.S., and 0.1%+0.1%F.S. accuracy for voltage, current and power measurement respectively.

The impressive front panel design includes iconic function selectors via rotary knob or arrow keys and a vacuum fluorescent display. For pain free viewing and access, the entire front panel tilts upward on 7U, 10U and 13U models. Operation can be achieved by the front panel or from a remote workstation via standard USB or optional Ethernet and GPIB interfaces.

The 63200A provides smart Master/Slave mode control which allows the engineer to program the load currents to the Master where they are automatically calculated and downloaded to the slave loads. This control dramatically simplifies operation when using several loads in parallel to emulate a single high power load. All models of the series can be integrated into a standard rack to save space.

Not found in conventional loads, the 63200A offers a dynamic frequency sweep with variable frequencies up to 50kHz. This capability is ideal for determining worst case voltage peaks. Using this function, measurement of the Vpeak (+/-) can be achieved with a sampling rate of 500kHz. The dynamic loading mode can simulate different loading conditions for most test requirements. Dedicated remote load sensors and control circuits provide minimum waveform distortion during dynamic loading.
