LDM1101 Semiconductor diode laser LD constant current drive module, 12A, continuous/pulse

Product reviews

Pulse constant current source driver module, can be used to drive LD semiconductor laser, output voltage adaptive, output current can be held through the user interface module UIM or host computer software flexible Settings.
Continuous current can be output;The output pulse current can also be digitally modulated;Can also simulate modulation output arbitrary waveform current.
Integrated multi-function signal generator, adjustable frequency and pulse width.The current can be modulated or output to an external Q switch.
Over current, over voltage, over temperature protection, optional automatic recovery function after failure.
High efficiency, simple heat dissipation, placed on the metal platform or installed on the metal case can be full load operation.
It can be run independently or can be controlled, recorded data and curve in real time by handheld user interface module or computer.
Open platform: provide complete serial port control command, users can program by themselves to control the driver module through the computer or single chip microcomputer: provide upper computer software for free, can achieve parameter observation, setting, data recording and curve display and other functions.
Powerful flexibility: various parameters can be adjusted, set and saved in the user’s software to facilitate the user to drive different semiconductor lasers.
Support 1 serial port control module, support and TCM series temperature control module.

Return drive

Output voltage adaptive: output current can be set by software: current soft start time can be set by software.
The “current modulation signal” of the output current can be set as three modes: continuous low, continuous high and digital modulation.
“Current modulation signal” is set as continuous low, output current is set by the parameter “bias current” software, output continuous current:
“Current modulation signal” is set as continuous high. The output current is set by the software of parameter “regulating current”. The output continuous current is:
“Current modulation signal” is set as digital modulation, and the output current will be modulated by the output signal of the signal generator, switching back and forth between “regulating current” and “bias current” to output pulse current
“Analog modulation interface” AI input signal output current can be (continuous) or after the digital modulation current simulation further modulation, arbitrary waveform output current: analog modulation function is optional, when A1 dangling, to drive the output current has no effect: when AI the input signal is too large, the output current is not more
