POWER SUPPLY MODEL 3001

The SCE 3001 is a hermetically sealed AC input, dual DC output power supply, used in the Aids to Navigation (ATON) equipment. It is a large linear supply that controls a flashing buoy. Noteworthy for its very tight transient requirements - 0 to full load can cause no more than a few percent overshoot. The power supply output circuit is capable of providing power to flashing incandescent lamps.

Voltage sag and overshoot on the flashing 3.05 Amp lamp must be less than 1% of the lowest operational output voltage (12VDC).

The unit must operate in a marine environment.
