microprocessing capability into each load module and mainframe
as the system operates in parallel processing mode to optimize
the speed and control among multiple load m od ules. All load
modules are configured to work synchronously, and testing can be

6310 SYSTEM BLOCK DIAGRAM
Th e C h r oma 631 4 12 0 0W and 6312 600 W e l ectro n ic load
mainframes accept the user-installable 6310 series load modules
for easy system configuration and fit 19" instrument rack. The
6314 holds four 63102 load modules at most to offer 8-channel
100W inp ut l oad with stan dard fron t-pan el i np uts. It fi ts for
testing multiple output switch power supply. Additionally, GO/NG
output port is useful for UUT's pass/fail judgement on automated
production line. All modules on the 6314/6312 mainframe share a
common GPIB address to synchronize and speed up the control of
load modules and read-back of operating data.

The 6310 family offers 8 types of load modules ranging from model
63101 with 200 watt s power to model 63112 with 1200 watts
power. Each model is designed with specific applications in mind.
In the world, model 63102 and 63107 are the only dual-input load
in one load module, capable of controlling loading up to 50A and
measuring voltage up to that of 0.5mV, and well-suited for testing
lower power, high precision DC/DC converter. Model 63105 and
63108 are designed to operate up to 500 V in high voltage testing
application. Model 63112 sinks a maximum current of 240A, and is
the most cost-effective in high power testing application.
3. Application of Specific Load Simulation
The 63 10 load modules op erate in consta nt current, con stant
res istance, or constant voltage to satisfy a wide ra nge of test
requirements. For example, the test of battery charger can be
simulated easily by setting the load to operate in constant voltage
mode.

The 6310 load module uses photo coupler for isolation between the
V
V
output and control sections, thus each load is isolated and floating.
The user can use multiple load modules independently to test
multi-output power supplies, or parallel them in high power testing
application.

Programmable Slew Rate
Each load module is designed with state-of-the-art technology
and connects all power MOSFET devices parallel to insure high
accuracy load control with minimum drift of less than 0.1% +0.1%
F.S. of the c urrent set ting. The FET t echnology accomplis hes
minimum input resistance and enables the load to sink high current
even at very low voltage. For example, model 63103 is capable of
sinking 60A at 1V output, and well-suited for testing the new 3.3V
low voltage power supplies. Low voltage operation, down to zero
volt, is possible at correspondingly reduced current level.

4. Dynamic Loading and Control
Modern electronic devices operate at very high speed, and perform
well in the transient and dynamic response of power devices. To
satisfy these testing applications, the 6310 loads offer high speed,
programmable dyna mic load simula tion and contro l c apability
never achieved before. The figure below shows the programmable
parameters of the 6310 load modules :

The programmable slew rate makes the simulation of transient
load change demanded by the requirement of real life application
pos sible. The 6310 internal waveform genera tor is capable of
producing maximum slew rate at 10A/µS, and dynamic cycling up
to 20KHz. Its dedicated remote load senses and controls circuit to
guarantee minimum waveform distortion during continuous load
changes.
5. Powerful Measurements
Each 6 310 load module has integrated a 1 5-bit precis ion A/D
converter for voltage measurement with an accuracy of 0.05%
+0.05% full scale. The built-in resistive load current sensing circuit
is capable of measuring current in an accuracy of 0.1%+0.1% full
scale. Also, short circuit can be simulated.All measurement is done
using remote sensing to eliminate any error due to voltage drop
along the measurement path.The user can also select a full setting
range of voltage and current measurement according to application
requirements.

as ATX power supply needs more channels in a load to simulate or
test the output than the traditional AT power supply. No doubt, you
really need a new solution for your test application! Chroma offers
a broad selection of load modules and at most an 8-channel load in
a standard mainframe. It is fit for any kinds of power supplies that
require different Power, Current or Voltage, and also for testing the
