The strobe needs: 15 Amps in 110 V system 10 Amps in 230 V system Ch1 is the FLASHRATE from 0/2 Hy to 17 Hz Ch2 is the BRIGHTNESS from 0% to 100% High-Intensity Flash Tube CAUTION! LIGHT FLASHES OF VERY HIGH INTENSITY! 2500 WATTS! To achieve ultra-high intensity at 110 V, we had to design a revolutionary tube. For comparison purposes, our surveys indicate that a normal XOP15-compatible tube would not working on this voltage system. We've even developed a new holder system to eliminate shipping damage to these high-performance tubes, which means a flexible lead-wire with copper lace. Considerable durability The circuits were designed with extra durability in mind. As a matter of fact, it is difficult to damage them under normal conditions. Past experience of TURBO strobes indicates that the average lifetime of our products is more than 6 years. The 3 indicator LED helps your work: USDMX is just a bit smaller than EURODMX. Control system It a can be controlled by those potmeters and DMX 512 controller. The unit has 2 DMX channels. Ch1 is the FLASHRATE from 0/2 Hz to 17 Hz Ch2 is the BRIGHTNESS from 0% to 100%
