SUPER-QUIET MERCURY-XENON LAMPS

Hamamatsu Photonics 

ACCESSORIES

LAMP POWER SUPPLIES

Using Mercury-Xenon lamps in photometric

applications requires an extremely stable power

supply. We recommend using Hamamatsu power

supplies to obtain full performance from super-quiet

Mercury-Xenon lamps. Hamamatsu provides two

types of power supplies: dropper type and switching

type. Dropper type power supplies feature extremely

high stability. Switching type power supplies have

less stability but offer advantages such as light weight

and high cost performance. Select the type that

meets your application.

Hamamatsu also manufactures various types of

OEM power supplies. Please feel free to consult us

with your specific needs.

NOTE: AExcluding projection parts.

BThe dropper type power supplies are used in conjection with the C4251 or C4339 Trigger Unit (option).

These power supplies use a trigger mode in which a positive high voltage is applied to the anode; so use care concerning the insulation for the anode.
