- There are three modes-operating mode, standby mode and error mode. With standby mode, pumping power and thermal-control power can be switch off. Operating mode is set as a default, if you want to switch to standby mode and set it as a default, it can be realized by laser communication instructions. In addition, it can also achieve power fail safeguard function.
- When power switch on, it can monitor and give feedback immediately. If it’s in error, it will self-check and report (every 1s on self-check).
- It is able to collect times of transmitting laser pulse.
- With external trigger operating mode(No more than 25Hz).
- With overvoltage safeguard function.
- With overcurrent safeguard function: when current in laser LD excesses the maximum value, it will switch to standby mode and send error report.
- With overheat safeguard function: when radiator temperature excesses the maximum value in standby mode, it will switch to standby mode and send error report.
