All the instruments are arc and short-circuit protected with separate programmable hard and soft current limits, making it possible to use them as constant current sources.
All models offer 1 V resolution along with 0.05% accuracy, 0.001% regulation and 0.0015% ripple. For local control applications, up to nine instrument configurations can be stored and recalled at any time, making it easy to run multiple tests.
Both GPIB and RS-232 computer interfaces are standard on the new 10 W supplies. GPIB is available as an option on the 25 W instruments. All parameters can be set and read via the computer interfaces. A rear-panel analogue input allows the high-voltage output to be programmed by a 0 to 10 V DC signal. Two rear-panel analogue outputs provide output voltage and current monitoring capabilities.
In common with all engineering products from SRS (Stanford Research Systems), the PS300 series is distributed in the UK by TTi.
