Chroma's new 62000P Series of programmable DC power
supplies offer many unique advantages for ATE
integration and testing. These advantage include a
constant power operating envelope, precision readback of
output current and voltage, output trigger signals as
well as the ability to create complex DC transients
waveforms to test device behaviour to spikes, drops, and
other voltage deviations. Designed for automated testing
DC-DC converters and similar products, the 62000P sets a
new standard for high accuracy programmable DC supplies.
The 62000P Series includes 12 different models ranging
from 600W to 5000W, up to 120A and up to 600V. Due to
their constant power operating envelope, a single
instrument can provide both high voltage/low current AND
low voltage/high current thereby reducing the number of
supplies needed in typical ATE applications.
The 62000P also includes 16 bit readback capability
for accurate voltage and current readings. This means
systems no longer need complex shunt/multiplexers to
make accurate readings of the UUT's input parameters.
The instruments also include I/O ports providing 8 bit
TTLs, DC-ON, fault output signal and remote inhibit as
well as a output trigger signal for system timing
Another unique capability of the 62000P supplies is
their ability to create complex DC transient waveforms.
This capability allows devices to be tested to DC
voltage dropouts, spikes and other voltage variations
making them an ideal choice for airborne device testing,
inverter testing and other devices which will experience
voltage interrupts. Applications include DC/DC Converter
& Inverter voltage drop test, engine start-up
simulation, battery automated charging, electronic
product life cycle test, and etc.
Wide Operating Region With Constant Power
The 62000P Series supplies offer a wide
operating region. For example, the output specification
for model 62012P-80-60 is 1200W/80V/60A, it allows
operating flexibly in various combinations as shown in
the figure at the right. As shown conventional power
supplies provide the same rated current at all output
voltages, however, the 62000P provides greater current
at lower output voltages. This means both low
voltage/high current and high voltage/low current UUTs
can be tested using a single supply avoiding the for
multiple supplies saving cost and space within typical
Programming Sequences Applications
The 62000P Series supplies allow for 100 user
programmable sequences with time settings ranging from
5ms to 15000s, voltage /current slew rate control and 8
bit TTL output for automated test applications.
Applications include DC/DC Converter & Inverter
voltage dropout testing, engine start-up simulation,
battery automated charging, product life cycle testing
and airborne avionics testing.
