Atec Chroma-6310A Series - Manual (Page 3)

The programmable slew rate makes the simulation of transient
load change demanded by real life applications possible. The
6310A internal waveform generator is capable of producing a
maximum slew rate at 10A/µs, and dynamic cycling up to 20kHz.
It's dedicated remote load sense and control circuit guarantee
minimum waveform distortion during continuous load changes.
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 for high power testing
applications.
Note: All specifications are measured at load input terminals. (Ambient Temperature of +25°C)

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 control and automated testing
applications. The USB and GPIB interfaces are available 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.

poWerful measurements
Each 6310A load module has an integrated 16-bit precision
A/D converter for voltage measurement with an accuracy 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
solution. The 6310A series will automatically detect the OCP
point, making it an ideal solution for design verification as well as
production line testing.
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
