Economical Arc Lamp Power Supply

Compact switch-mode power source for UV curing lamps


Expand AllCollapse
Product Summary

This compact switch-mode power source in the economical arc lamp power supply provides constant power to a 400 / 600W mercury vapor bulb or medium pressure metal halide arc lamp. The supply is available in a 100 / 120AC (400W: UV0902, 600W: UV2279) or a 200 / 240 AC (400W: UV1241, 600W: UV1242) version to accommodate international use.

A “standby” switch signal is provided for reducing lamp output power while the system is idle—to 1/2 for the 400W and 1/3 for the 600W. This can reduce excess heat and power consumption, thereby increasing system reliability and efficiency and reducing ambient temperature rise. The UV flood curing system’s power supply also contains an un-isolated 12V output for powering a local cooling fan. An integrated lamp igniter eliminates the need for an external high-voltage starter.

Additional Details

Two input voltage range options: The unit is available in a 90–132AC or 180–265AC 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 (two 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.

Status indicators: An on-board ready LED is provided to indicate that lamp warm-up is complete.
