Regulator Deckhand - 24 V DC 6 A

The BLUE SEA Deckhand 7504-BSS dimmer is a digital device designed to control the brightness of onboard lighting systems. 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 on a nominal voltage of 24 V DC. Its operating range is from 18 V to 32 V DC.

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

Brightness is controlled via pulse-width modulation (PWM), ensuring smooth and progressive adjustment of 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 high (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: After the first flash, hold the switch in the high (illuminated) position for 1 to 4 seconds. 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 drive is equipped with built-in overcurrent protection. If the unit stops working, first correct the cause of the overload (excessive current load), then hold the drive switch pressed until the circuit flashes to reset it.

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

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

The Deckhand autopilot's maximum parasitic consumption is 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 installing multiple drives side by side in a compact manner, thus optimizing the available space on the electrical panel.

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

The dimmer 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 gray 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 dimmer.

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

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

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 or could damage the dimmer or the lights.

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