Chroma Launches Its New Cost-effective High Power DC Electronic Loads – 63200E Series

Posted on January 3, 2018July 27, 2018 by Philip Bailey

Chroma launched the new generation high performance high power DC electronic load 63200A series in 2016 and received wide appreciation from customers. In order to serve more customers and to cover greater applications, Chroma followed up by launching the high cost-performance 63200E series with power rating from 2kW to 24kW.
The 63200E Series has a high power density (6kW @ 4U) to meet the green energy power testing requirements for solar energy, hydrogen, fuel cells, and electric vehicles related products.
In addition to the basic CC, CR, CP and CV modes, the 63200E Series can be used in the field of electric vehicle testing and also has a battery discharge mode to satisfy the discharge test requirements for car battery packs. The 63200E Series can record the Wh and Ah during battery discharge. For DC power and components in the electric vehicle such as a car charger, D / D converter, fuel cells, fuses, switches and wiring, etc., all models have functions that can correspond to the tests.

To comply with the high voltage car charger (600V or more) and the low voltage D/D convert (150V or less), the 63200E DC loads has three operating voltages available – 150V, 600V and 1200V. For voltage and current specifications, each model has 3 settings and 3 measurement ranges. The maximum current output of a single load is up to 2,000A, with power up to 24kW. A maximum power up to 240kW can be achieved by using multiple loads in parallel for greater power testing demands.
The 63200E DC load also has a pulse current loading function to test the fuses, switches and wiring by setting the repeat time to 1 in the existing dynamic loading mode.
The extremely bright VFD display adopted by the 63200E DC load allows users a clear view of test results.

Moreover, depending on the desired power level, the DC loads are packaged into either desktop or tower types. On the tower type, the operation panel tilts so that users can easily view and operate the unit whether sitting or standing. All models of the series are designed to a uniform width. Both desktop and tower type models can be mounted into a standard 41U rack enclosure in order to maximize space.

Fast Transients, Low Noise in
Chroma’s New Benchtop DC Power Supplies

As Chroma’s next generation of power supplies, the 62000L Series delivers pure and stable DC power as well as built-in features designed to meet the stringent requirements of next generation power electronics including automotive power electronics MCU/ECU, communication electronic parts, and semiconductor IC drivers.

Fast transient response makes the output voltage that changed due to load characteristics return to a stable supply of power in microsecond response speed. Take the 62010L-36-7 model for example, when the output current changes from half load to full load at the speed of 1A/?s, the voltage change of the actual output can return to 15mV within 30?s.

Low noise input power with pure quality protects the precision load or UUT from the interference of heavy noise. For example, the 62010L-36-7 output voltage noise is lower than 2mVp-p (20~20MHz) under the maximum rated current and maximum output power.

The auto sequencing programming function built into the 62000L Series allows the user to define and edit the output waveforms with 8 steps per cycle.

Conventional linear power supplies are cumbersome due to the frequency design and require more space for ventilation. Chroma simplified the design of the hardware architecture resulting in a better handling compact, lightweight design which is safer to stack.

The brand new 62000L Series programmable DC power supplies features an affordable price, high quality output specifications, practical functions, and standard USB and GPIB communication interfaces making this an excellent choice for testing small power and precision products.
