Simpledrive I r6 (feb 2015) (L mount version) One channel high side analog laser diode driver with bias suppression, overheat protection features, interlock input and current monitor output. Compatible with any analog and 5V CMOS signals, Arduino PWM, e.t.c. => Capable of driving many popular laser diodes. => Wide modulation bandwidth, high linearity => Standby bias suppression function (1) with turn-off delay (2) => Start delay => Overheat shutdown protection (3) => Interlock shutdown input => Manual zero current balance adjustment => High side design => Output for current measurement - You can use a voltmeter for current measurement without breaking the circuit. Recommended a voltmeter with 0,01 - 0,001V resolution => Status LED (power-on/laser emission/overheat status displayed by one LED) => 1/3A operation jumper for changing the maximum current limit. Specs: Supply voltage 4 ... 24V* DC Output (drive) current 100 ... 3000 mA Bias current 0 ... 400 mA Modulation input 0 ... 5V (analog) Bias suppression threshold (sensitivity) 0.1 V Bias turn-off delay 0.2 sec Modulation bandwidth 100+ KHz Start-up delay 4 sec Overheat shutdown t? 35-75 ?C Interlock input levels TTL/CMOS compatible PCB dimensions 25 x 36 x 20 mm *This driver can operate at a supply voltage upto 24V with subject to certain requirements. Recommended supply voltage 5-15V. 1. Standby bias suppression suppression feature - this feature also has another name - standby beam suppression (SBS). The main idea of this feature - when the modulation signal is missing - the bias current is automatically deactivated 2. Bias turn-off delay - this feature designed to achieve optimal lasing parameters at high modulation frequencies. 3. Overheat protection - to protect your laser diodes you can use the built-in automatic overtemp shutdown feature. You just need to attach NTC sensor to diode heatsink and set the desired operation temperature threshold. You can use this driver without this feature, just don't connect sensor to the board. 4. Interlock input - This input is used to enable / disable the driver by a signal from another device This driver is supplied with 20 - 30cm wires kit and 10K NTC sensor. In order to avoid thermal damage, do not use the driver without heatsink! By default items shipped via airmail economy with ~10-20 days delivery time. Thanks for looking!
