Input Power Supply: AC220V±20% 50±3Hz Output Voltage [LD;Adaptive Load]: 3~12.5V,Adaptive Load Output Current [LD;Continuously Adjustable]: 0.1~12A, continuously adjustable

The STYA-12V12A-1T-SY semiconductor-laser driver power supply is part of the company's experimental series, featuring ultralow current ripple and temperature drift, high stability, and high reliability. PWM conversion provides high overall efficiency. Control is available from the front panel, an external-control interface, or remotely from a computer through RS232. LD protection includes overcurrent, overvoltage, overtemperature, and antistatic measures, plus an emergency laser-output termination function and button. Front-panel switches select local/remote and internal/external control. The display shows set current, measured current, measured temperature, and current limit. Internal data storage can save supply-state parameters at any time. A configurable current limit prevents the operating setpoint from exceeding the selected limit. LD temperature is measured and displayed in real time, with the control temperature adjustable from the front panel. Status LEDs show the operating state. The rear DB15 external interface supports current setting and start/stop control, and provides real-time current-feedback, power-supply fault, and external-equipment interlock signals. In remote mode, the host computer can set current, start or stop output, query parameters at any time, and receive information transmitted by the supply.

The STYA-06V50A-2T-Q-WZ semiconductor-laser driver power supply is designed for LD-pumped solid-state lasers, supplying the pump source and RF signal required by the Q-switch. It also provides TEC temperature-control circuits for the LD and frequency-doubling crystal. Internal TTL pulse-generation and control circuits offer adjustable width and frequency. Q-drive control can be internal, using the supply's TTL pulses and control, or external, using external equipment. Current control likewise switches between internal front-panel touchscreen/buttons for setting and start/stop, and external analog current setting with TTL start/stop. RS232 remote control allows current setting, start/stop, status queries, and receipt of supply information. The supply stores5 common output modes with preset current, pulse width, and frequency for quick operation. Automatic storage saves current settings and restores the last-used mode at the next startup; usage information is also stored for queries. Every design stage considers applicable laser-equipment safety standards and meets the relevant safety criteria.
