Power 512~1400W DC/DC Diode Laser Modular Drivers

SYL series diode drivers are designed as individual modules and they are very easily integrated into the user’s power supply or control systems. These modules are DC/DC current-constant output or AC/DC voltage-constant plus DC/DC current-constant output. The user can design his own display to show the driving current, voltage, temperature etc. Our drive modules are widely used in laser diodes, diode chips, LEDs and fiber lasers.
