The Norman D24 power supply operates with all Series 900 Commercial lampheads.
The D24 is a compact 2400 watt/second power supply, making it an ideal unit for location flash photography.
The power adjusts from full to -5 stops in .1 stop increments. All power levels are visible from the bright LED readouts.
In the symmetrical mode, the circuit has two 1200 w/s channels. Each channel supports two heads, and each features a separate continuous sweep flash dimming dial.
A Slow Charge selector allows use of the pack on location where there is sub-par wiring.
