Shelyak High Voltage Power Supply (PF0082)

Shelyak High Voltage Power Supply

High voltage power supply for spectral calibration lamps.

This power supply is intended for “spectral lamps” which require high voltage (up to 300V DC) and current regulation (adjustable from a few mA to 35mA).

It can power hollow cathode lamps (HCL) such as the Thorium/Argon lamp used on the eShel and Whoopshel spectrographs. In this case, remember to also take the “cable for hollow cathode lamp” (ref. SE0268).

It can also be used for Neon or Argon / Neon lamps, used on LISA, Lhires III or UVEX.

Technically, this power supply raises the voltage, to excite the gas of the lamp. The ignition voltage depends on the gas; for example 60V is enough to excite Neon, while it takes more than 230V to excite Thorium. Then, the current is regulated at the chosen level (a few mA for Neon, and about 10mA for Thorium).

In addition, the power supply has a power limitation to reduce the risk of damage to the lamps.

This power supply is therefore suitable for any lamp requiring up to 300V to be excited and up to a current of 35mA. Suffice to say that it can power almost any gas lamp.

The 3-pin male connector alone is available as an option (Ref. EL0334) to allow you to create the cable of your choice.

This high voltage power supply requires a 12V power supply like the one offered under reference EL0073.
