  • Output voltage regulation better than ±0.3%
  • Up to two discharge channels per one 19” case
  • LAN, RS232, CAN computer interface options.
  • USB for software update
  • Measuring of discharge current and voltage traces and last shot energy


  • Glass amplifier pumping
  • Intense pulsed lighting (IPL)


PS514x series flashlamp drivers are designed for multi-lamp pumping of high energy pump chambers usually based on phosphate or silicate glass rods. This is highly-customizable power supply containing one-channel charging unit PS514xk and required quantity of one or two channel discharging units PS514xi. Each discharging channel is suited to drive one lamp. The PS514x has as many discharge channels as pump chamber has flashlamps. All discharging channels works synchronically. Usually, high energy systems work at very low repetition rate – not exceeding 1 Hz down to 1 shoot per hour. Hence simmer option is not applicable and lamp igniting (triggering) appears with every discharge. We usually recommend external lamp igniting with separate igniting unit (one- or multi-channel). However internal serial igniting is possible in some cases as well.

Description of PS514x given here is only as one example of possibilities to built high energy powering system, and any time by ordering it can be flexibly changed. All set of charging and discharging units can be mounted to 19” standard racks (sold separately).
