Wavelength Electronics Introduces Compact Linear Laser Diode Driver to 12.5 A
- The PLD-CH Chassis Mount Series has a NEW 12.5 A Model – the PLD12.5K-CH
15, 2011 -- The popular PLD-CH Series is now available in a 12.5 A model. This new driver supports fiber-coupled
lasers used in applications such as medical, dental, micro-machining, material processing, semiconductor
inspection, and imaging.
The PLD-CH Series offers single-supply low voltage operation from +5 V DC, which
minimizes heat dissipation. For applications that require a higher forward voltage, a separate laser diode power
supply input allows for flexible compliance voltages up to +28 VDC.
Safety is paramount on all Wavelength Electronics controllers. The PLD-CH Series safety features include:
· Slow start circuit · Mechanical shorting relay · Active Current Limit
These offer maximum protection for your laser diode even when power is removed. The Active Current Limit not
only protects your laser diode, but ensures that you are operating with maximum stability. Two photodiode ranges
provide variable sensitivities for optimum performance. You can maintain excellent stability in both Constant
Current and Constant Power mode. The PLD-CH Series supports all laser diode / photodiode pin configurations. The
12.5 A model has a 50 kHz Bandwidth with < 0.05% output stability, one-hour stability of < 200 ppm and a < 200
ppm/ºC temperature coefficient.
Other features include: · Remote Enable/Disable ·
Remote monitoring · Analog modulation of setpoint current · Drivers can be paralleled for up
to 25 A of stable output current
Wavelength Electronics has simplified advanced laser diode drive and thermal control technology for OEM and
research applications since 1993. Our high performance specifications are supported by a team of experienced
sales and design engineers and a state-of-the-art manufacturing facility.
