Microprocessor controlled power pack with 2 lamp base connections. Automatic adaptation to the respective mains (AC-line) voltage. Flash energy 1600J (Japanese version 1200J). Symmetrical and variable individual (asymmetrical) output distribution. Control range: over 6 f-stops in 1/10 f-stop intervals; when switching over to asymmetrical mode 7,3 f-stops. Internal discharge when power setting is reduced. Photocell (can be switched off) and separate infrared receiver (can be switched off). Illuminated silicone keyboard and LED-display, resistant to dust and scratches. Modelling light with 5 proportionality levels, adjustable to all broncolor power packs and compact units. Ready display visual and audible. Dim-function of the modelling light during charging. Ready buzzer (can be switched off). Can be switched to slow charging mode. High repetitive precision for digital photography. Compatible with the entire broncolor lamp base range. The power pack is equipped with a switching mechanism to approach a stabilization of the colour temperature (CTC light). Thereby in the symmetrical mode the colour temperature can be maintained steady over a range of approx. 3 f-stops within +/-150 K. Integrated RFS interface (Radio Frequency System) for remote control respectively flash release of the unit by radio via a transmitter RFS as well as by means of a transceiver RFS from PC or Macintosh computer. When controlling via screen, 4 storage spaces for different lighting situations are at your disposal.
