LDQCW Quasi-CW Diode Laser Drivers
The LDQCW series is a new family of OEM diode laser pulsars designed for the emerging high power diode laser industry. Lumina Power LDQCW diode drivers can be configured for compliance voltage requirements up to 100V.
Maximum efficiency is realized with circuitry that minimizes losses across the output pulsing circuit. Compact size is possible due
to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics.
Leakage current is less than 250uA, power factor is greater than 0.99 and conducted emissions meet stringent European regulations. No additional line filter is required to meet EN 55011 emission requirements
