Quantum's QUPAC is an optional AC module for studio use. Use the Qpaq-X flash/power system in the studio for portraits, formals, product shots or just when you need an uninterrupted power source.
Note: Requires PR1, 2 , 3 or PRV charger.
The PB1 or PB2 units go below this one. I bought this for my studio because the weakness of the Quantum QPaq X system is poor battery life. Unfortunately I learned the hard way that if your battery dies, you cannot use this "AC" module. �Your flashes will not charge or fire. �End os game. Thois "AC module" will not overide a dead battery to power your flash. �It is not a true AC Power unit. �In fact, I dont know what it's function is over the charger that comes with the top module unit. �It's basically an expensive paer weight, useless accessory if you dont use you Qpaq regularly and have fresh PB2 batteries (as a regular working pro might). You may wish to conatct quantum instruments to see about the Pure AC unit instead it's the PR-4 module, part number�860216.
I use it on location and studio settings when power outlet is available. This unit serves as power supply and battery charger unit at the same time.
