The XPS-200 Power supply is a highly stable current source for xenon and mercury-xenon arc lamps. It has a built-in automatic igniter controller, however, to reduce the electromagnetic interference the igniter itself has to be mounted in a shielded lamp enclosure.
The XPS-200 is compatible with Solar Light's line of Solar Simulators (Models 16S and 601). In conjunction with an igniter also available from solar light it can be used with any lamp from 50 to 200 Watts.
The XPS-200 power supply comes with the line cord as specified by the customer. It can be configured for 115 or 230 VAC operation.
By employing modern switching technology the size and weight of the power supply is considerably lower compared to equivalent products.
Due to a high switching frequency and multiple output filters the current ripple was virtually eliminated assuring long life of the xenon lamp.
Internal ignition counter stops the automatic ignition cycle after approximately 10 attempts. An external temperature sensor can be connected to provide thermal shutdown should the lamp overheat. A current error indicator warns if the power supply is nearing maximum output voltage and may not continue to stabilize the lamp current.
The power supply senses the connection to the solar simulator and automatically initiates the ignition cycle upon power-up. If the lamp does not ignite after several attempts the power supply pauses and displays an IGNITION ERROR.
The thermal sensor input provides a means to shut the system down if the light source is overheated. An OVERHEATING ERROR is set to indicate this condition.
The operating voltage of Xenon arc lamps increases with it's usage. If this voltage rises above the maximum capacity of the power supply the current stabilization may not be accurate. A CURRENT ERROR indicator signals this condition.
