Arc Lamp Power Supplies

Xenon & Mercury Short-Arc Lamp Power Supplies
Arc Lamp Power Supply

XLB Series

The XLB series Arc Lamp Power Supplies are designed to operate Xenon short-arc lamps offered by all major lamp manufacturers.   To precisely control the lamp's light output, the XLB power supplies deliver a constant current that can be adjusted and monitored via the analog interface.   The high-frequency inverter section eliminates power supply-induced “arc wander” and reduces ripple to <0.5%.  Available in 7 power levels from 650 to 6500 watts, these power supplies are ideal for applications in stage lighting, digital projection solar simulation, and medical illumination.

MLB Series

Mercury short arc lamps exhibit a change in impedance as the lamp transitions from a cold start to steady-state operating temperatures.  To control this operating condition, MLB short-arc lamp power supplies are designed to output constant power to the lamp regardless of the temperature.  This ability to maintain precise control over the light output of the lamp is vital for precision applications in semiconductor fabrication and various UV processing equipment.   Available in 6 power levels from 650 to 5000 watts, the MLB mercury arc lamp power supplies are a compact, highly regulated replacement for conventional 60Hz ballast power supplies.

Short Arc Igniters

Igniting short arc lamps requires an initial high-voltage pulse to create the arc across the lamp's electrodes. In the past brute force trigger transformers would produce the high voltage but in doing so the high current would slowly damage the electrodes.   The short pulse igniters, standard for all XLB and MLB power supplies deliver a low energy, 1µsec. pulse that reliably ignites the lamp while substantially reducing electrode wear.
