Uvitron Economical UV Arc Lamp Power Supply

Product Summary

This compact switch-mode power source provides constant power to a 400/600 Watt mercury vapor or metal halide medium pressure arc lamp. The supply is available in a 100/120VAC (400W: UV0902, 600W: UV2279) or a 200/240VAC (400W: UV1241, 600W: UV1242) version to accommodate international use. A "standby" switch signal is provided for reducing output power while the system is idle. The unit also contains an un-isolated 12 Volt output for powering a local cooling fan. An integrated lamp igniter is provided which eliminates the need for an external high-voltage starter.

Two Input Voltage Range Options Available

The unit is available in a 90 to 132VAC or 180 to 265VAC input range making the Uvitron lamp power supply easy to use in any country.

Integrated High-Voltage Lamp Starter

The unit’s lamp starter provides up to 10kV, enough voltage for igniting virtually any lamp. This high voltage capability allows instant hot lamp restarts after short line voltage interruptions (2 seconds typical). The igniter also has a timeout shutdown feature for protection with defective or disconnected lamps.

Lamp Power Regulation

To maintain constant power, the system divides the desired output power by the actual 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 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, efficiency and reducing ambient temperature rise.

Status Indicators

An on-board Ready LED is provided which lights to indicate that lamp warm-up has completed.
