Oriel 68805 Power Supply 40-200 Watt

Oriel 68805 He / HgXe / Hg 40-200 Watt Arc Lamp Power Supply was designed to meet the needs of the researcher who demands a highly regulated source of current for proper operation of arc lamp light sources. Constant current operation of these sources of radiation is required whenever a radiometric measurement is being made or whenever a highly stable light output is needed.

Arc lamp sources will be operated in constant current mode by the Oriel Model 68805 power supply with the output voltage being dependent on the arc lamp’s impedance. The Oriel Model 68805 power supply will provide a constant current of up to 11 amperes with a load voltage range of 0 to 100 volts. A power limit, which limits the product of output voltage and current to 300 watts, protects the unit from output overloads. A constant current power supply regulates current even into a short circuit, and the model 68805 is safely limited to 12 amperes or 300 watts. Also, the inrush current to the lamp is limited to a maximum of 12 amperes, and the reduced discharge current minimizes electrode erosion when starting the arc lamp. The Oriel model 68805 Arc Lamp Power Supply includes all of the circuitry to power the lamps, to operate the required external ignitor or ignitor built into Oriel arc lamp housing, and to meter the output parameters.
