Dimmer Deckhand – 24 V DC 6 A

The Deckhand 7504-BSS dimmer from BLUE SEA is a digital device designed to control the brightness of lighting systems on board boats. It is specifically designed for 24 V DC systems and manages unregulated LEDs, incandescent bulbs, and halogen lights.

This dimmer is designed to control the intensity of unregulated LEDs, incandescent bulbs, and halogen lights.

The Deckhand 7504-BSS variable speed drive operates at a nominal voltage of 24 V DC. Its operating range is from 18 V to 32 V DC.

The maximum output current the Deckhand 7504-BSS drive can deliver is 6 amperes (6 A).

Brightness is controlled via pulse-width modulation (PWM), ensuring smooth and progressive variation in light intensity.

The 'Bulb Saver' function is an integrated system that extends the lifespan of bulbs. It prevents excessive aging of bulbs when the boat's batteries are being charged.

To activate the illuminated output function:

For a 1-minute delay: Hold the switch in the upper (illuminated) position for 2 seconds. The lights will flash. Release the switch after the first flash and the lights will remain on for 1 minute.

For a 2 to 5-minute delay: Hold the switch in the upper (illuminated) position for 1 to 4 seconds after the first flash. Release the switch after 2 to 5 flashes. The lights will stay on for 1 minute per flash, up to a maximum of 5 minutes.

The Deckhand autopilot drive has built-in overcurrent protection. If the unit stops working, first correct the cause of the overload (excessive current load), then hold the autopilot drive switch pressed until the circuit flashes to reset it.

Yes, the Deckhand dimmer features a memory function that retains the last used light intensity setting.

The variable frequency drive is designed to operate across a wide temperature range, from -40°C to 85°C.

The Deckhand autopilot drive has a maximum parasitic draw of less than 2 mA.

No, this specific model (7504-BSS) is designed for 24 V DC systems. BLUE SEA offers other Deckhand models for 12 V DC systems.

Yes, the Deckhand dimmer is designed to support multiple switch locations, allowing brightness control from different points on board.

The offset mounting tabs allow multiple drives to be installed side by side in a compact arrangement, optimizing the available space on the electrical panel.

The dimmer is supplied with a momentary (ON)-OFF-(ON) switch (part number PN 8216).

The inverter is connected as follows:

The red wire connects to the +24V DC power supply.The two black wires connect to ground (negative bus bar).The blue wire connects to the lamp.The grey and white wires are the inputs for the switch (Down Input and Up Input).A fuse must be installed on the +24V DC line before the inverter.

The Deckhand 7504-BSS autopilot drive has a width of 3.25 inches (82.55 mm) and a height of 3.5 inches (88.9 mm).

Yes, this variable speed drive is E-marked and complies with the external ignition protection requirements of ISO 8846 and SAE J1171 standards. It also meets SAE J1455 and SAE J1113 standards.

No, the Deckhand 7504-BSS dimmer is specifically designed for unregulated LEDs as well as incandescent and halogen bulbs. Using it with already regulated LEDs may not work properly and could damage the dimmer or the lights.

Yes, a fuse must be installed on the +24V DC power line before the speed controller to protect the circuit, as shown in the installation diagram.
