Newport 69907 – Arc Lamp Power Supply, Universal, 40 to 200 Watt

The Newport 69907 is a universal arc lamp power supply engineered to operate high-power arc lamps from 40 to 200 watts, with maximum capability extending to 300 watts. It delivers stable, regulated output in either constant power or constant current mode—essential for radiometric measurements, solar simulation, and light source applications demanding consistent illumination. The supply accommodates mercury, xenon, and mercury-xenon arc lamps and integrates with Newport and Oriel lamp housings and solar simulator systems.

– Key Features

• Digital Display monitors current, voltage, power output, and lamp run time; allows preset and limit configuration with user memory functions
• LED Status Indicators communicate power supply operating conditions
• Start/Stop Control ignites lamps at preset values to minimize transient overshoot/undershoot and manages controlled shutdown with cooling
• Safety Interlock Connector (12 VDC/GND) prevents output activation until satisfied and disables supply if disconnected during operation
• Remote I/O (15-pin D-SUB) provides external control input (2.5–5 VDC for up to 20% output reduction), remote start/stop, and analog meter outputs: Power (0–2.0 V = 0–300 W), Current (0–2.0 V = 0–12 A), Voltage (0–2.5 V = 0–100 V)
• RS-232 Communication enables remote operation and monitoring via lamp-specific interconnection cables
• Optional IEEE-488 (GPIB) interface available for automated control and data acquisition

– Typical Applications

Solar simulation, spectroscopy, radiometric calibration, and photometric testing environments requiring stable, long-arc illumination with precise output regulation.

– Compatibility & Integration

Works with Research and Q Series lamp housings, Newport solar simulators, and mercury and xenon arc lamp sources across the 40–300 W operating envelope.
