Shasta High Voltage Power Supply 

 

voltage. Ensure that the creepage and clearance distances between the high voltage output and 
the enclosure meet the requirements of a suitable safety standard, e.g., EN60950 or EN61010. 

8)  The power supply should only be operated with the HV output cable connected. 
9)  Ensure adequate ventilation of the power supply to ensure that possible ozone build up will be 

kept to a safe level. 

10) There are no user serviceable parts in the power supply. If the power supply fails to operate, it 

must be returned to Oxford Instruments or to an Oxford Instruments authorized service center for 
repair. 

11) Do not use the power supply if it is damaged. Return to Oxford Instruments, or to an Oxford 

Instruments authorized service center for examination. 

12) The power supply should only be used for the purpose for which it is designed and manufactured.  

Failure to do this may impair the protection provided by the power supply. 

 

Regulatory Compliance 

Meets the requirements of IEC61010-1:2010, EN61010-1:2010, UL61010-1:2012 and CAN/CSA C22.2 
No. 61010-1:2012. The product carries the TUV SUD c/us mark. 
 
By complying with BS EN61010-1:2010 it meets the requirements of the Low Voltage Directive (LVD), 
2006/95/EC when it is installed as a component part of other equipment. It is CE Marked accordingly. 
 
An M5 earth terminal is provided for a protective earth, this shall be connected to a safety earth at all 
times when the unit is operational. 
 
The input power shall be removed from the unit before removal of any covers or working on the HV unit. 

 

Quality Management System 

Oxford Instruments X-Ray Technology is certified to ISO 9001:2008. 

 

Reliability 

Mean time between failures (MTBF) is greater than 40000 hours in accordance with MIL-HDBK-217E. 

 

 

EMC 

The Shasta power supply is intended for installation as part of a system. Basic EMC filtering is provided. 
The EMC performance of the power supply can only be assessed when it is installed within and as part 
of the final system.
