FLD-nano flashlamp driver

FLD-nano is a compact but powerful flashlamp driver (flash lamp power supply) designed for air-cooled flashlamps, flash lamp tubes, similar to the depicted below.

Driver charges an external capacitor bank up to required voltage and then, following an external TTL signal, initiates a discharge by applying a trigger pulse (400V by default) to a flashlamp. Recommended flash lamp tube circuit layout is shown below:

FLD-nano requires +24 V DC power supply and pulse generator to set an operating frequency.

An output voltage level can be programmed in working range by user either manually (through onboard configuration trimpot) or remotely (applying a DC voltage to the respective pin). The driver maximal output power could be decreased, if needed, by onboard trimpot.

Two different operating modes are possible:

• manual mode, when an output voltage level is regulated by onboard trimpot, flash lamp operating frequency could be either set automatically in autorun mode or regulated (by external pulse generator or by button);
• using a controlling device, when output voltage level is varied by applying a DC voltage to the respective pin. Other functions (Enable, TTL) are also could be controlled by this device, depending on user system layout.
