Simplify complete laser diode control. The WTCP PWM 5A 5V Temperature Controller combines high efficiency pulse-width modulated (PWM) control with temperature stability to 0.0009 °C. The WLD3343 Laser Diode Driver supplies up to 3 A of current. Laser diode and thermoelectric safety circuits are integrated, including current ramp with delay and current limits. Ideal for portable, airborne and other space-constrained applications.
