Compact laboratory power supplies extend to 20 kV
The SRS PS300 series of high-voltage power supplies, sold in the UK by TTi, has been 
extended to include 10 kV and 20 kV models for both positive and negative polarity.
These four new single-output models each have a power rating of 10 W. The full PS300 range also includes 25 W dual-output models which cover ±1.25 kV up to ±5 kV. All models are housed in a compact half-rack case suitable for bench or rack mounting.
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.
