Technical datasheet for the Yexian Technology LPM1201 laser diode power module with LD driver and TEC temperature control.
The LPM1201 is a laser diode power module that integrates LD driver functionality with TEC temperature control. It supports adaptive output voltage, software‑settable current, and multiple modulation modes (continuous, digital pulse, analog waveform). The module offers full protection features, an open‑platform serial command set, and can be controlled via computer, handheld interface, or microcontroller.
The datasheet provides detailed electrical specifications, interface pin definitions, connector types, installation dimensions, and warranty information. It also describes the module’s operating environment, temperature sensor options, and remote control interfaces. This manual is written in Chinese.
