Overview

The Lumitec 101528 is a replacement power supply and control box for the Mantis dock lighting system, converting 100 to 120VAC (50/60Hz) to 24VDC for the lights.

It is meant to mount above the waterline in an outdoor wet location, feeding the dock lights on the low-voltage side through the bottom cable glands. Total connected load should stay at or below 110W, and the supply is intended for up to four Mantis-Quattro lights on one power unit.

This is a practical fit when your Mantis lights and cabling are already in place and you need to bring the system back online with the correct power and switching behavior.

Key features

• Input power: 100 to 120VAC, 50/60Hz, for connection to a GFCI-protected circuit
• 24VDC output for Mantis dock lights; connections are made on the low-voltage side (red to red, black to black)
• Rated for up to 110W maximum load and supports up to 4 Mantis-Quattro lights on one power unit
• Weatherproof enclosure for outdoor wet locations; install at least 1 foot above ground with cables pointing down
• Can be switched with a timer, photocell, or toggle switch feeding the receptacle; do not connect the power unit to a dimmer

Installation and setup

Plan the mounting location so every light cable reaches the power unit without chafe points, and keep all installer-made connections outside the body of water. The enclosure should not be submerged and should be kept out of spots that take repeated direct wave action.

High-voltage components are prewired inside the unit, so field wiring is focused on the 24VDC side. Route the low-voltage cables in through the bottom glands, tighten the glands to support the cables, then make the DC connections with no bare conductor exposed.

Compatibility and fit

This power supply is used with Mantis dock lighting systems and is intended for installations where the underwater lights are fully submerged in fresh or salt water. For system planning, the listed maximum depth is 8 feet, and cable splices need to stay outside the water even with tidal changes.

Maintenance and care

Disconnect power before opening the enclosure or servicing the system. Periodically check for loose connections, damaged cable jackets, heat discoloration, and signs of corrosion or water intrusion inside the unit, especially in saltwater environments.
