Product Summary

This full-featured arc lamp power supply’s switching power supply is a constant power source for a 400 / 600 / 800W UV halide or other types of ultraviolet emitting lamps. It features an auto-ranging AC input, eliminating the need to configure voltage selectors for international use, and a “standby” logic signal for reducing output power while the system is idle. The unit also contains an isolated 5 / 24V supply for powering system controllers, fans, shutters, etc.



Additional Details

Auto-range AC line input: The auto-ranging 100–120 ±10% / 200–240 ±10%AC line input makes the lamp power supply easy to use in any country, with no wiring changes or voltage select switching required.

Lamp power regulation: To maintain constant power, the system divides the desired output power by the actual UV arc lamp voltage. This provides the appropriate current reference for the lamp regulator to compensate for lamp and line voltage variations. The result is repeatable curing times as the lamp ages, when the lamp is replaced, or when the input voltage fluctuates.

Standby power mode: The unit has an external standby input for reducing UV arc lamp power to 1/2 for the 400W and 1/3 for the 600W. This can reduce excess heat and power consumption during idle, therefore increasing system reliability and efficiency and reducing ambient temperature rise.
