High Voltage Power Supplies for PMT's	Specifications S502B and S512B Dimensions S502R and S512R Dimensions
This Products for Research series of high voltage power supplies is designed to meet the demands of currently available high gain photomultiplier tubes. While the 0 to -3000 V DC range of the S502 is adequate for the great majority of tubes, the 0 to -5000 V DC of the S512 and the dual output 0 to +1500 V DC / 0 to -5000 V DC of the S509 power supplies are also available to fulfill some of the more exacting requirements. This equipment is designed with the intent of maximum convenience to the operator. All models are provided with unitized high voltage modules which allows for simple field interchange in the unlikely event that this should be required. Variations on the voltage and current output are available on special request.	The S502 and S512 high voltage power supplies are available in either a rack style chassis (supplied with feet for bench use) or a bench style chassis. Use the suffix 'R' to designate rack (S502R and S512R) or the suffix 'B' to designate bench (S502B and S512B). The S504, S507 and S510 supplies, available only with non 'CE' marked, 'TE' type units, come integrated into the standard 19" relay rack/bench cabinet of the Products for Research LN2 or thermoelectric cooler power supply, thereby affording the convenience of only one piece of equipment to accomplish two tasks.
