B+K Precision Corporation, represented in Australia by Unispan Instruments Pty Ltd , has introduced the Model 9122, the third of a new family of programmable, single output digital dc power supplies.

Using a standard 240Vac outlet as the power source, this new bench top unit provides clean, stable and reliable power, and offers a programmable output of 0V to 60V, 0A to 2.5A.

The Model 9122 offers exceptional control and accuracy and is the ideal supply for educational, service and maintenance, R&D lab verification and manufacturing.

Features of the Model 9122 include:

* 10mV and 1mA display resolution

* Over-voltage protection

* RS-232 interface

* SCPI compatible

* Remote sensing

* Front and rear output terminals

* Low noise

* Excellent regulation

* Temperature stability

* Fast transient response time

* Closed case calibration

* Sheathed safety banana jacks.

The Model 9122 is suitable for low power surface mount circuits that require very precise voltage and current settings.

New microprocessor control circuitry permits the Model 9122 to offer unmatched temperature stability and remarkably fast transient response times with a load regulation of 0.01% +3mV.

The unit can power-up to the same state it was when it was powered-off. This allows the supply 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.

The Model 9122 comes with an RS-232 interface that permits the user to program both voltage and current through a standard serial COM port. All of the power supply parameters can be programmed and monitored.

For safety, the Model 9122 uses 4mm sheathed safety banana jacks. The jacks are designed for safe interfacing and allows the unit to meet the latest international safety standards.

Front panel indicators and controls include an OFF/ON power switch, a high resolution LCD, closed case calibration, and encoder knob for quick analogue-like control.

The compact bench top unit (8cm x 21cm x 38cm) weighs only 5.6kg and features rear output and remote sensing terminals.

Available for immediate delivery, the Model 9122 comes with B&K Precision Corporation's one-year warranty, user manual, and line cord. A number of accessories are available.
