Atec Chroma-63600 Series - Manual (Page 3)

Chroma's 63600 Series Programmable Electronic Load integrates micro-processing capability into each load module to optimize the speed and control
among multiple load modules. All load modules are configured to work independently, though testing can be carried out simultaneously at multiple
outputs via remote control to simulate real life application.

APPlICATION OF SPECIFIC lOAd SImulATION
The Chroma 63600 electronic load mainframe accepts the user-installable 63600 series
load modules for easy system configuration. The model 63600-5 mainframe holds five
63610 load modules to offer up to 10 100W load input channels with standard front-
panel inputs. The maximum power for a single mainframe is 2kW when five 63640-80-80
load modules are paralleled. This is suitable for testing multiple output switch mode
power supplies, and many other types of power products. Using the GO/NG output port,
production snapshots are made available to show the immediate pass/fail judgment of
UUT. All modules on the mainframe share a common GPIB address to synchronize and
speed up the control of the load modules and read back the operating data.
The 63600 series load modules operate in constant voltage, current, resistance, power, or impedance to satisfy a wide range of test requirements. For
example, the CV is designed to simulate batteries for charger testing.

The 63600 series provides three operating current ranges and a built-in 16-bit, precision A/D converter, achieving 0.025%+0.01%F.S., 0.05%+0.05%F.S.
and 0.1%+0.1%F.S. accuracy for voltage, current and power measurement respectively. Precise measurements like these are ideal for testing power
efficiency and other critical parameters of the UUT's. The precise measurement of 63600 series also meets the requirements of ENERGY STAR® and 80 Plus.
Besides, The 63600 series can measure OCP/OLP trip voltage and current by setting the step, step current, dwell time and so on. Then 63600 series will
judge the test result for Pass or Fail and shows the maximum power (Pmax) on the display after completed the OCP/OLP test.
Two high-speed A/D are built in the 63600 series to measure the voltage and current at the same time and calculate the true power value for displaying
without distortion
