LDxCHA Series Low Noise LD Driver Board

◆Adjustable clipping current◆Power-saving protection, over-voltage protection◆RMS noise current is low noise at 35μA at 100kHz

◆ Bandwidth up to 600 kHz at a constant current ◆ ACC (constant current) or APC (constant power) mode ◆ Equipped with safety features to protect the laser (slow start, delay circuit) The LDxCHA series is a low-noise LD driver that supports a maximum supply current of 15A and a maximum supply voltage of 3V or 28V (when set to high voltage). The new circuitry allows for fine-tuning of the current limit and current set point even in the absence of a signal from the laser. This enables users to operate safely without worrying about power settings and prevents overdriving. The LDxCHA series is compact, and the base hole pattern allows for direct mounting on engineering tables or within systems. Two trim pots are set for current limit and set point, and simple wiring is facilitated by five spring-loaded terminal blocks. The built-in safety features stabilize operating conditions and enhance product robustness. The setting of the current limit value ensures that the output current will never be exceeded, and the slow start function prevents overdriving. It offers high reliability and long operating times.
