The full power 400 w/s Power Pack with X-tra Fast 2.5 second recycling time is made to be used with the Quantum™ X series Heads or any of Lumedyne's Heads used with an Auto Module for power control. The Quantamatic Packs have an On/Off switch and a Battery Gauge, that's it. There is no power level switch to accidentally have in the wrong power setting. Fewer parts make the Pack slightly less expensive than a similar Pack with power control, but it also has fewer components that could possibly fail or malfunction.
All of Quantum's TTL and Digital TTL features function normally.
Power up to 400 Watt/Seconds
Using a Booster Module to power a QFX Head above 400 w/s will damage the head immediately.
The Lumedyne style Head Jack can also be used at full power with any Lumedyne Flash Head. Lumedyne's Auto Modules and Flash Heads can be Boosted up to 2400 w/s provided you have a 2400 w/s Quartz Flashtube.
Optional Power Adapters
A variety of AC adapters, and a vehicle adapter are available.
