EU-38-TTL TECHNICAL DATA Laser Diode Driver Features • • • constant laser diode current adjustable with potentiometer modulation input laser diode output power independent from supply voltage Specification • • • • • dimension: 35 x 15 mm² (+/- 0.5 mm) supply voltage: 4.0 - 5.0 VDC max laser diode current: 1 A modulation frequency: DC .. 100 kHz, analog and digital voltage input modulation input voltage: 0 V = laser off, UB = laser on, any voltage between 0 and UB possible (>2 V = high) P1 Ub (supply voltage +) GND (supply voltage -) modulation input laser diode anode (+) laser diode cathode (-) CAUTION for high currents use a heat sink transistor gets hot P1: trim pot for laser diode current adjustment turn left = laser diode current increase turn right = laser diode current decrease Note: P1 is a trim pot which can be turned clockwise and counterclockwise slowly to the end points. The trim pot can be damaged, if you keep on turining it at the end point ! 26.06.2013 EU-38-TTL 1 of 1
