SRS Stanford PS310 High Voltage Power Supply PS300 Series High Voltage Power Supply

The PS300 high voltage power supply offers output voltages of 1.25KV, 2.5KV, 5KV, 10KV, and 20KV. Voltage resolution and resettability are as high as 1V, with voltage setting accuracy reaching 0.01%. Response time is less than 10μs. Voltage regulation accuracy is up to 0.001%. Output ripple is 0.0015% of full scale.

The PS300 series high voltage power supply—rugged, compact, and reliable instruments for high voltage applications. With output capabilities up to 20 kilovolts, GPIB computer interface, 0.001% voltage regulation, SRS high voltage power supplies have become an industry standard. 
Several models are available, ranging from 1.25 kilovolts to 20 kilovolts output.

The PS310, PS325, and PS350 are bipolar, 25W power supplies, while the PS355, PS365, PS370, and PS375 are unipolar, 10W power supplies. All power supplies feature short-circuit protection and independent programmable software current limiting, allowing them to function as constant current sources.

Appropriate Features 
No matter which model you choose, you will appreciate the convenience and versatility of the PS300 series high voltage power supplies. Two large LED displays monitor output voltage and current delivered to the load. Overload reset, limit and trip status, local/remote status, and high voltage can also be displayed, allowing you to monitor the instrument's status at a glance. A highly visible red indicator light constantly reminds you to be cautious of high voltage.

Ease of Use
Operation is simple—adjust or set parameters are displayed separately and can be operated without affecting the actual output voltage. 

Remote Programming 
Standard GPIB and RS-232 computer interfaces, 10W power. GPIB is available as an accessory for 25W power supplies. All parameters can be set and read via computer interface. 

Analog Monitoring and Control
The rear panel analog input allows a 0 to 10 VDC signal to program the high voltage output. Two rear panel analog outputs provide output voltage and current monitoring functions. These outputs drive 10 mA current and have a 1Ω output impedance. 

Performance and Value
The PS300 series high voltage power supplies are highly useful in R&D laboratories and automated testing applications. Wherever you use high voltage power supplies, the PS300 series offers a cost-effective and high-performance choice.
