4. rev 1 05 2013 1001 PDD 02 Pulsed laser diode driver User manual Read carefully this document before start operations Overview Applications PDD 02 is a pulsed diode driver with the possibility of high current operations The maximal output current is 200A The maximal output voltage is 6V The maximal output power is 100W 150W in dependence on the configuration Both short and long pulse widths are possible In some cases CW operations is also possible Since PDD 02 supposes a lot of modifications different with current voltage pulse width at the stage of inquiry we ask you to specify the parameters you need 1 maximal output current Imax up to 200A 2 maximal compliance voltage Vmax up to 6V 3 maximal pulse width needed Tmax up to CW 4 maximal repetition rate needed Fmax up to 10kHz Example PDD 02 200A 2V 300us 100Hz Cooling coverage case Module is supplied as a printed board sandwich with a preinstalled fan Appearance DIODE AIR FLOW INTERFACE 442V pc Connections signals signal descriptions POWER INPUT Power input is organized with two wires thick enough to supply high currents needed Power input positive is marked with a piece of red shrink tube Recommended power input voltage is 1V above the actual diode voltage measured with the voltage meter Higher input voltage is possible but the maximal output power is reduced 12V DC 2 PIN MOLEX MINIF
5. us with proper cable Current overshoot 5 of Imax Current regulation accuracy lt 1 of Imax recommended input voltage depends on the actual diode voltage and preferably should be 2 6V higher different input voltage increases heat dissipation in driver s components and thus decreases the performance these parameters aren t independent and cannot achieve their maximums at the same time because of possible driver s overheating even if the input voltage is properly selected the maximal output power cannot exceed 120W 150W
