The Stanford Research Systems PS300 Series High Voltage Power Supplies—rugged, compact, reliable instruments for just about any high voltage application. With up to 20 kV output capability, a GPIB computer interface, and 0.001 % voltage regulation, these high voltage power supplies have become the industry standard.
There are several models to choose from, with outputs ranging from 1.25 kV to 20 kV:
|
Model |
Output Voltage |
Current |
|
PS310 |
±12 V to ±1.25 kV |
20 mA |
|
PS325 |
±25 V to ±2.5 kV |
10 mA |
|
PS350 |
±100 V to ±5 kV |
5 mA |
|
PS355 |
-100 V to -10 kV |
1 mA |
|
PS365 |
+100 V to +10 kV |
1 mA |
|
PS370 |
-100 V to -20 kV |
0.5 mA |
|
PS375 |
+100 V to +20 kV |
0.5 mA |
The PS310, PS325 and PS350 are dual-polarity, 25W supplies, while the PS355, PS365, PS370 and PS375 are single-polarity, 10 W supplies. All of 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.
The Right Features
Whichever model you choose, you’ll appreciate the convenience and versatility of the PS300 Series. Two large LED displays monitor the output voltage and current being delivered to your load. Overload reset, limit and trip status, local/remote state, and high voltage enable are also displayed, so you can monitor the instrument status at a glance. A highly visible red LED always indicates when the high voltage is on.
Easy to Use
Operation is simple. The parameter being adjusted or set is displayed separately and can be entered without affecting the actual output voltage. Up to nine instrument configurations can be stored and recalled at any time, making it easy to run multiple tests.
Analog Monitoring and Control
A rear-panel analog input allows the high voltage output to be programmed by a 0 to 10 VDC signal. Two rear-panel analog outputs provide output voltage and current monitoring capabilities. These outputs drive up to 10 mA of current and have 1 Ω output impedance.
Performance and Value
The PS300 Series High Voltage Power Supplies are as useful in the R&D lab as they are in automated test applications. Wherever you are using them, the PS300 Series provide proven reliability and performance at a very affordable price.
Remote Programming
Both GPIB and RS-232 computer interfaces are standard on all 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.
