Speed and accuracy for test optimization– F ast, low-noise outputs– A nalog control of output voltage and current– F an-speed control to minimize acoustic noise– B uilt-in measurements and advanced
programmable features– P rotection features to ensure DUT safety

Data SheetThis series of 500 W linear-regulated DC power supplies is designed to maximize the throughput of DUTs through the manufacturing test process with fastup and down programming time.
Valuable assemblies can be destroyed by a minor component failure that causesa surge of current to flow into the DUT. Fast protection features, including fastcrowbar, mode crossover protection, and the ability to connect the protection
circuitry of multiple power supplies can increase production yield.
Programming of the DC output and the protection features can be done either
from the front panel or using industry standard SCPI commands, via the GPIB.
Using the serial link, up to 16 power supplies can be connected through one
GPIB address. Test system integration can be further simplified be using theVXIplug&play drivers. The output voltage and current can also be controlledwith analog signals. This is helpful for certain types of noisy environments, andalso immediate reactions to process changes.
Lab bench use is enhanced by the fan speed control, which helps to minimize
acoustic noise.

Supplemental characteristics
for all model numbers

AC input: (AC input frequency 47 to 63 Hz)

DC floating voltage: Output terminals can be floated up to ±240 VDC from chassis ground
Remote sensing: Up to half the rated output voltage canbe dropped in each load lead. The drop in the load leads
subtracts from the voltage available for the load.
Command processing time: Average time required for theoutput voltage to begin to change following receipt of digital data is 20 ms for the power supplies connected directly tothe GPIB
Output programming response time: The rise and fall time
(10/90% and 90/10%) of the output voltage is less than 15
ms. The output voltage change settles within 1 LSB (0.025%x rated voltage) of final value in less than 60 ms.
Down programming: An active down programmer sinks
approximately 20% of the rated output current
Modulation: (Analog programming of output voltage andcurrent)
