These affordable miniature laser diode controller circuits are manufactured by Lasertack, Germany, and offer a precision current source up to 2500mA and up to 2 Amps of power to a TEC cooler. They are supplied by a voltage 5 to 12 VDC power supply input and offer the user a wide modulation bandwidth of 500 kHz Analog from a voltage source of DC to 5V. They offer a fast rise and fall time specification, and a low noise specification of <1.6 millivolts. The TEC controller loop is unidirectional (cool only). and they offer a very high temperature control accuracy of 0.1°C. These controller modules were designed for high power laser diodes. KEY FEATURES: LED indicators: The LED indicators show the real-time state of all functions and the driver state. Normal condition operation or failure state mode is immediately shown by LED indicators. Temperature monitoring: With a 10Kohm thermistor temperature sensor connected, temperature monitoring is active. The measured values are used for over-temperature shutdown and for the TEC controller. Safety shutdown: The driver shuts down the output to the laser diode when over-temperature is detected or the interlock loop is broken. The LED indicators show which failure mode occurred. Active and passive interlocks: Active and passive interlock loops can be utilized. A simple door switch or a 5V interlock loop can be connected. Turn-on delay: After connecting the power supply, the driver allows the PSU to stabilize before enabling the laser output. Programmable failure treatment: In the case of a failure because of over-temperature or a broken interlock, the driver can handle the situation in two ways. It can restart the laser when the failure caused problem is solved automatically or it will wait for a restart signal. The programming is done by the shorting of of the two connector pins pairs.
