Download manual (1.5 MB)The NBU-1012 discharge circuit is designed to simplify the development of solid-state laser systems. The module forms quasi-rectangular pulses on a flashlamp (using energy stored in an external capacitor bank). It also provides simmer current during the intervals between pulses. By default, NBU-1012 includes capabilities both for series and external triggering.
The flashlamp operating frequency and pulse duration can be varied using a +5 V TTL signal from an external control device sent to the respective pin.
The module includes an IGBT with its driver, protective circuits, simmer and trigger circuits, discharge resistors and control electronics. It also contains a fan for active cooling.
It’s important to emphasize that the discharge circuit NBU-1012 is not a stand-alone solution. For proper operation it requires capacitor charging power supply and capacitor bank, an external control device to form the pulses, external +24 V DC power supply, as well as some minor parts (see also the picture below). We would be happy to recommend modules from our range to suit your system.

Simplified as well as more complicated modifications of the NBU-1012 are available upon request.
We have also a new model NBU-1112 discharge circuit, which is similar to this NBU-1012 model, but it is slightly different in size, more technologically advanced. It is also more suitable for certification.
The NBU-1508 discharge circuit forms bell-shaped pulses of fixed length on a flashlamp. Typical applications are Q-switched Nd:YAG lasers or similar.
The NBU-1312 is the most powerful discharge circuit by OEM Tech. With a maximum average power of 4 kW and a maximum output voltage of 1300 V, it is intended for driving two flashlamps connected in series in high-power Nd:YAG and Alexandrite aesthetic laser systems.
For high-power IPL and long-pulsed Nd:YAG, KTP, Alexandrite laser systems we offer the NBD-0505-PWM discharge circuit with PWM (pulse-width modulation) technology. The module forms rectangular or quasi-rectangular pulses on a flashlamp.
