| Post subject: | AB800 power draw - practical experience? |
Hi All, The FAQs have given me most of the info I was looking for regarding power consumption of PCB strobes but I am hunting for anybody's practical experience in a home setup. It says that each light will draw a peak of 16-18A for 200ms (called "well tolerated by most home circuits") but if I have 3 AB800s all recycling on the same circuit, I'm gonna trip something, right? My concern is this - I'm pretty sure that in the area I am designating the studio I have no more than two separate 15A circuits. I know this will be no problem managing the 3x 8A RMS (including modeling lights) but when I pop, I'm sure to trip a breaker, no? Or will home wiring "tolerate" ~48A for 200ms? (I'm gonna say no.) Cheers, John |

You will probably be fine. Circuit breakers and fuses do not act instantaneously and will likely ride through the recycle without an issue. In my house I can run two Einsteins and an ABR 800 off a single 15 A circuit. Also, I don't think your 8 amp RMS number is right... each light will draw 1-2 amps when not recycling (depending on the model lamp setting) and an average of 6 amps during recycle with the brief peak that you mentioned of 17 amps or so. Happy Shooting :P |

If you fire the lights absolutely as soon as they recycle, with modeling lamps on full power continuously, each light will draw about 7A RMS. Thus 3 lights will draw about 21A RMS. This will take a typical 15A household breaker about 15 minutes to 1 hour to break. |

Perfect. Thanks, guys! You've set my mind at ease. Now, time to spend some money... |
