Laser Diode Drivers
Oct 2010Portable Power Systems Inc.Request Info
The PPS-150 series laser diode drivers manufactured by Portable
Power Systems provide up to 150 A of continuous-wave or pulsed current at various
compliance voltages. The units are microprocessor-controlled with electrically erasable
programmable read-only memory for storing the last set parameters for the laser.
The devices have internal pulse, frequency and current generation and are supplied
with coolant and remote interlocks, laser and driver overtemperature protection,
and overvoltage and overcurrent protection. There is also reverse electromotive
force protection at the laser itself. The PPS-150-50DP model offers a rise/fall
time of 15 μs, compliance voltage of 50 V, an RS-232 interface and front panel
control. Other features of all models in the series include floating output and
an adjustable current limit.
