LDY High Power Diode Laser Drivers

The LDY series is a new family of OEM laser diode drivers with all the performance of Lumina’s flagship LDD line of laser diode drivers, as well as additional functions including pulsing capability, over-temperature sensing and crowbar shorting of the output.

The LDY series is ideal for high power applications where economy is important and performance cannot be compromised. Compact size is possible due to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics. The LDY is virtually wire free.

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. The LDY family has been designed with the knowledge that a high power laser diode is an expensive device. Rise and fall times are strictly controlled to reduce high voltage transients which could damage the laser diode.
