QBX-08 is a dedicated Pockels cell drivers designed for applications where voltage on the Pockels cell should be continuously adjustable. Driver is built on voltage amplifier schematics, maximal output voltage is 800V (other voltages both smaller and higher up to 1600V are available on request), amplification factor is 100:1.

Driver is forced air cooled with embedded fan. Driver can be supplied in PCB and enclosed versions.
