LRC SERIES

Low cost, robust and reliable laser power supply with superpulse capability

300 watt and 700 watt high voltage power supplies for use in Carbon Dioxide Medical and Industrial Lasers

Description

Universal Voltronics Series LRC high voltage power supplies are optimized for use in mid-power carbon dioxide and similar laser applications. Of particular significance are the robust and reliable design architecture, and the “superpulsing” capability of this series: maximum pulse currents of up to 60 mA and repetition rates to 2 kHz are available at 100% duty cycle. Series LRC provides full power at 75% of maximum voltage.

Power in this series is switched at a 42 kHz switching frequency for best efficiency and lowest heat generation. Current mode operation eliminates the need for a discharge ballast element.

Series LRC is ideal for original equipment CO2 laser applications because of its rugged and durable circuitry, compact footprint, efficiency, choice of open-frame or enclosed configurations, and availability of remote control.
