optimize the speed and control among multiple load modules.

All load modules may be configured to work synchronously, to

test multiple outputs simultaneously, thus simulating real life

applications.

multiple output switching power supplies and multiple DC-DC converters.

There are also higher wattage modules that may be mixed and matched

for an even more versatile system. Additionally, the GO/NG output port

is useful for UUT's pass/fail testing on an automated production line. All

modules on the 6314A/6312A mainframe share a common GPIB address

to synchronize and speed up the control of the load modules and the read-

back of data.

Compatibility WitH 6310 series

The 6310A series load modules will be compatible with the

6310 series mainframes (6312/6314). In addition, the remote

control commands will be compatible between the 6310 and

the 6310A series without needing to r e-writ in g any remote

control programs.

module load design

The Chroma 6314A 1200W and 6312A 600W electronic load

mainfram es a ccept the user-ins tallabl e 6310A series load

modules for easy system configuration and will mount in a

19" instrument rack. The 6314A holds up to four 63102A load

modules, which will result in an 8-channel 100W/channel load

with standard front-panel inputs. This makes it ideal for testing

appliCation of speCifiC load simulation

The 6310A load modules operate in constant current, constant voltage,

constant power or const ant r esistance to satisfy a wide range of test

requirements. For example, the test of a battery charger can be simulated

easily by setting the load to operate in constant voltage.

current setting. Chroma's use of FET technology provides minimum input

resistance and enables the load to sink high current even at very low

voltages. For example, the model 63103A is capable of sinking 60A at 1V,

and well-suited for testing the new 3.3V low voltage power supplies. Low

voltage operation, down to zero volts, is possible at reduced current levels.

parallel Control

The 6310A provides parallel control, which enables high power

testing when a single module cannot meet the requirement of high

power applications. Two or more load modules can be paralleled

together to achieve the desired loading. The 6310A comes with

RS-232 as standard for remote contr ol and automated testing

appl ica tions. T he U SB and GPIB inter fac es are availa ble as

options.

In addition, the 6310A, through its synchronized controls, provides

an efficient solution for testing single output AC to DC or DC to DC

converters by controlling multiple loads. The 6310A provides the

capability to test up to 8 UUTs at a time.

dynamiC loading and Control

Modern electronic devices operate at very high speeds and require

fast dynamic operation of their power providing components. To

satisfy these testing applications, the 6310A loads offer high speed,

programmable dynamic load simulation and control capability. The

figure below shows the programmable parameters of the 6310A

modules:

Ea ch 6310A load m odul e has an int egra ted 16-b it precis ion

A/D conve rte r for voltage measu rem ent wit h an a ccu rac y of

0.025%+0.025% of full scale. The built-in resistive load current

sensing circuit is capable of measuring current with an accuracy

of 0.05%+0.05% of full scale. Also, short circuit can be simulated.

All measurements are done using remote sensing to eliminate

any error due to voltage drops along the measurement path. The

user can also select from a complete set of voltage and current

measurements.

oCp test

Modern switching power supplies are designed with over current

protection (OCP) circuitry; therefore, it is important to test the

OCP circuitry to make sure it is functioning within its designed

specifications. The 6310A series provides an easy and fast solution

for this testing.

By simply choosing the channel and setting the OCP parameters

(start current, end current, step current and dwell time) from the

front panel, the 6310A series provides a fast and easy OCP testing

soluti on. T he 6310A serie s will automat icall y dete ct t he O CP

point, making it an ideal solution for design verification as well as

production line testing.
