Oriel Deuterium Lamp Power Supplies We offer highly regulated, constant current power sources to run most 30 W deuterium lamps. We offer two models of supplies: • Fully Featured Model The 68840 has a number of user features, and is current adjustable from 200 to 550 mA • OEM Model For fixed current applications, this model is a more economical alternative Tech Note Deuterium lamps require filament power and anode-cathode voltage of at least 350 V to initiate the discharge and then, for best performance, carefully regulated discharge current. The 68840 and 68942 are constant current power supplies. Until the deuterium lamp reaches thermal equilibrium, the radiated output varies. After approximately 10 to 15 minutes, the output will be almost completely stable. For applications requiring extreme stability, an additional 15 to 30 minutes of warm-up may be required. This is particularly important when using the 63345 Calibrated Lamp (see page 72). • Operates most Deuterium lamps • Low cost OEM version and fully featured version • Current is adjustable from 200 mA to 550 mA • Highly regulated, <0.5% light ripple Specifications 68942 Fully Featured 68942 OEM AC Input 95 - 132/190 - 264 VAC, 50/60 Hz 95 - 132/190 - 264 VAC, 50/60 Hz Output Current 300 mA 300 mA Ripple with ohmic load ±0.05 %, max ±0.05 %, max Light Ripple (peak to peak) * <0.5 % <0.5 % Line/load regulation ±0.01 % ±0.01 % Output Voltage Range 60 - 90 VDC 60 - 90 VDC Pre-ignition voltage 100 V, ±5 % 100 V, ±5 % Ignition Voltage 570, ±30 V peak 570, ±30 V peak Max. temperature 10 - 40 °C 10 - 40 °C * When an Oriel Lamp is operated in appropriate Oriel Lamp Housing from Newport.
