The Broncolor Grafit A4 RFS Power Pack provides: independent 1/10 stop control of each flash head; up to 3200Ws; selectable flash duration; consistent color temperature; and advanced menu-driven functions, plus it comes with a built-in radio slave receiver for sure-fire wireless triggering of the pack from the optional RFS transmitter (162080). This power pack may also be fired from a Mac or Windows-based computer with the optional RFS transceiver (162081).
Broncolor power packs are designed for long life under heavy use. Long-life capacitors, extra-high capacity components and solid state design ensure trouble-free operation for years, and are designed with maximum safety in mind.
Digital controls can be returned to exactly the same settings an hour or a year later. The current power packs share the same lampheads, and are also compatible with many older packs, ensuring that equipment will hold its value over many years.
