The Horiba/PTI LPS-220 is a highly regulated DC power supply engineered to deliver stable, consistent power to arc and halogen lamp sources in analytical and spectroscopic systems. Built for Mercury, Xenon, Mercury/Xenon compact arc, and Tungsten-Halogen lamps operating between 75 and 150 watts, the unit maintains output current through automatic voltage regulation to ensure repeatability and accuracy in experimental measurements.
## Technical Specifications
• **Lamp Compatibility:** Mercury, Xenon, Mercury/Xenon compact arc lamps, Tungsten-Halogen lamps
• **Power Output Range:** 75 to 150 watts
• **Output Control:** Adjustable current control with automatic voltage tracking
• **Warm-up Stability:** Xenon lamps achieve stable operation within 5 minutes
• **Display:** Digital meter selectable for volts, watts, or amps
• **Input Voltage:** 115 V or 220 V operation
• **Fusing:** Slow-blow (115 V/4 A or 220 V/2 A) and fast-blow (10 A) fuses, selected via rear-panel circuit card
• **Cooling:** Internal fan with rear-panel heat sink; adequate ventilation required
## Key Features
• Manual and automatic arc ignition with external lamp igniter support
• Approximately +100 V bias across output terminals before ignition
• 30 kV ignition pulse generated by pressing IGNITE button or automatically ~15 seconds after power-up
• Automatic re-ignition upon power restoration
• Color-coordinated rear-panel connectors for lamp housing connections
• Red and black output cables supplied
## Compatibility & Integration
The LPS-220 integrates with external lamp igniters for arc lamp systems. Do not use with PTI model LPS-221 Igniter; non-specified component interchange voids warranty and risks permanent equipment damage. Compatible with separate lamp housings via supplied output cables.
