Description
The NBU-0808 discharge circuit is a module designed to streamline the development of solid-state laser systems. This module is adept at forming quasi-rectangular pulses on a flashlamp using energy stored in an external capacitor bank. It is equipped with essential components such as an IGBT, its driver, protective circuits, as well as simmer and trigger circuits, all meticulously engineered for optimal performance.
The NBU-0808 includes all necessary circuits to manage discharge resistors, but it does not come with embedded discharge resistors. However, these can be easily acquired as accessories, tailored to different sizes and resistances.
It's crucial to note that the NBU-0808 is not a standalone solution. It requires additional components such as a capacitor charging power supply, a capacitor bank, and some minor parts and controls to function effectively. By default, the NBU-0808 is equipped with capabilities for both serial and external triggering, providing flexibility for various applications.
Custom modifications, whether simplified or more complex, are available upon request to better suit specific needs.
A significant feature of the NBU-0808 is the distinct and visible separation between low voltage and high voltage parts. The 24V power input and all interface circuits are separated from the high voltage circuits by a 4mm creepage distance and solid insulation, ensuring safety with a test voltage of 2500VAC. In summary, the NBU-0808 discharge circuit is a versatile and reliable module designed to enhance the development of solid-state laser systems. With its comprehensive design and customizable features, it stands as a valuable component for professionals in the field.
