Single Output Programmable DC Power Supplies

The 9120 series power supplies are designed to meet the needs of today's applica-

tions in R&D design verification, university labs, production testing, and other appli-

cations that require clean/reliable power and excellent performance. With meter reso-

lution of 10mV and 1mA, these power supplies are ideal for low power surface

mount circuits that require very precise voltage and current settings.

New microprocessor control circuitry allows these power supplies to offer unmatched temperature stability and remarkably

fast transient response times with a load regulation of 0.01% + 3mV. These power supplies are smart enough to power-up

in to the same state they were when they were powered off. This allows the units to go back to work as soon as power is

restored whether the power-off was intentional or caused by a power outage. There is enough non-volatile memory to store

up to 100 power supply settings allowing quick and easy testing when multiple voltage and current values are required.
