Description
The NBD-0505-PWM is an advanced discharge circuit meticulously crafted to streamline the development of IPL and solid-state laser systems. This module is adept at forming flashlamp pulses of both rectangular and quasi-rectangular shapes by utilizing energy stored in an external capacitor bank. Key components of this module include an IGBT, its driver, protective circuits, as well as simmer and trigger circuits, discharge resistors, and controls. One of the standout features of the NBD-0505-PWM is its advanced current control through Pulse Width Modulation (PWM), which enables the creation of true rectangular pulses. This is particularly beneficial for applications demanding precise current stabilization, as evidenced by the typical waveform outputs. The module’s capability in maintaining a steady 500A current is a testament to its robust engineering. It is crucial to note that the NBD-0505-PWM is not designed to function as a standalone unit. For optimal performance, it requires integration with a capacitor charging power supply and a capacitor bank, in addition to some ancillary components and controls. This integration ensures that the module operates efficiently and meets the specific demands of your laser system applications. The NBD-0505-PWM is an essential tool for professionals seeking precision and reliability in laser system development. Its dual-channel output, with distinct operations for PWM and free-discharge, provides versatility and adaptability, making it a valuable addition to any advanced laser setup.
