Features


  • Dual Channel Discharge Circuit: The NBD-0505-PWM features two outputs: one for PWM operations and another for free-discharge operations. Outputs can be used sequentially, not simultaneously.

  • Output #1 (PWM): Delivers up to 2000W, with a maximum voltage of 500V and current of 500A. Provides true rectangular pulse widths from 0.3ms to 100ms and supports both current and voltage stabilization modes.

  • Output #2 (Free Discharge): Capable of up to 2000W, with a maximum voltage of 800V and current of 800A. Offers quasi-rectangular pulse widths from 50µs to 10ms.

  • Powerful Simmer Board: Designed to drive two flashlamps connected in series, ensuring consistent performance.

  • Serial Triggering: Available on both channels, with external triggering available upon request.

  • Integrated Capacitor Bank: Features approximately 1mF at 800V, supporting high-performance operations.

  • Advanced Current Control (PWM): Enables true rectangular pulses, enhancing system efficiency and performance.

  • Specifications:

    • +24V DC: Voltage regulations with a maximum power consumption of up to 10A.

    • Integrated Inductance Coil: 80µH for efficient energy management.

    • Simmer Parameters: Simmer current of 500mA, with a maximum output voltage of 300V and power of 100W.

    • Flashlamp Triggering Parameters: Open circuit voltage of 1500V to ensure reliable triggering.



  • Recommended Wiring: Use FLEXI-2V or similar wires (>1000V rated voltage, >4mm² cross-section) for capacitor bank and inductance coil connections. Additional insulation or spacing is required for flashlamp connections due to serial triggering.

Applications


  • Development of IPL and Solid-State Laser Systems: The NBD-0505-PWM is specifically designed to support the creation of Intense Pulsed Light (IPL) and solid-state laser systems by forming flashlamp pulses using stored energy from an external capacitor bank.

  • Rectangular and Quasi-Rectangular Pulse Formation: Enables the generation of true rectangular pulses through advanced current control (PWM), providing precise pulse shaping.
