Product Introduction

Laser Diode Drivers

The compact PLD-CH Series are our most popular laser diode controllers. The mount-anywhere modular package style and cabled connections give you the fl exibility to place the laser driver at the ideal location within your system chassis. Using a single 5 VDC power supply you can drive lasers up to 3 V compliance. Lasers with higher compliance voltage—up to 28 V—can be accommodated by using separate supplies for the laser and electronics.



- Models driving up to 5 A, 10 A, or 12.5 A 

- Single 5 V supply operation up to 10 A 

- Compliance voltage up to 28 VDC with separate power supply 

- Slow-start laser diode protection 

- Constant Current or Constant Power mode 

- Latching current limit 

- Mechanical relay protection 

- Remote Enable / Disable pin 

- Onboard setpoint and limit trimpots 

- Parallel two units to drive up to 25 A
