Marine Connectors, Power Supplies, and Wiring

A high-quality marine inverter with pure sine wave output, available in 600W and 1000W models, designed to power sensitive onboard appliances with grid-quality electricity. This inverter converts your 12V battery into stable 230V AC, allowing you to run devices like laptops, TVs, microwaves, or chargers on your boat just as you would at home. It features dual AC outlets (European Schuko and UK) and an integrated RCD (ground fault circuit breaker) for maximum safety. With a rugged design and configurable grounding, it’s perfectly suited for marine environments.

• True Sine Wave: Delivers a clean sine wave output – safe for all types of equipment, including sensitive electronics, with no risk of interference or damage that modified wave inverters might cause.
• Two Models: 600W (for smaller loads) and 1000W (for heavier appliances) – choose based on your power needs. Both models offer high surge capacity to handle start-up currents of devices.
• Dual Outlets & RCD: Equipped with both a Euro Schuko and a UK-style AC outlet, capable of 230V (and 110V if required). Built-in RCD (residual current device) adds safety by preventing electric shocks, especially important in damp marine conditions.
• Marine-Ready Design: Provides option for neutral-ground bonding or floating ground (selectable) to integrate properly with yacht electrical systems. Gold-plated terminals and high-quality components ensure minimal loss and reliable operation.
• Quiet Cooling: Features an upgraded large cooling fan that runs efficiently at lower RPM – meaning quieter operation even under load.

A waterproof 4-pole electrical connector for deck power. This female plastic coupler has four terminals (max 3A each) and a protective cap, designed for flush mounting on a deck or console panel. It provides a reliable multi-wire connection for low-current devices on the boat, and remains sealed against spray and corrosion when not in use.

• 4 pins, 3A each – supports three conductors plus ground or other complex wiring (e.g. +12V / –12V / signal / ground)
• Weather-proof – tethered cap with gasket keeps water out of the connector (suitable for exterior mounting)
• Durable plastic body – UV-resistant, impact-resistant construction, prevents terminal corrosion
• Easy installation – mounts with nut or bolts; requires matching 4-pin male plug for operation

The Pro Power Q series offers affordable modified sine wave inverters, providing reliable 12V to 230V power conversion for most household devices on board. They are the budget-friendly solution to power up about 95% of appliances – perfect for those who want shore-like comforts at a lower cost. The range spans from small 150W units (for laptops and chargers) to powerful 2000+ W units (for tools and high-draw appliances). All models feature dual AC outlets (EU and UK style) and provide 230V 50Hz (and 110V 50Hz) output through built-in sockets. Gold-plated connectors, a large cooling fan, and overload protections make these inverters a dependable choice for a wide variety of uses.

• Modified Sine Wave: Compatible with ~95% of appliances – suitable for hairdryers, laptop adapters, phone chargers, TVs, microwaves, etc. (not recommended only for certain devices with thyristor controls like washing machines or bread makers).
• Cost-Effective: Priced around half of equivalent pure sine inverters, making it excellent for those on a budget or for infrequent AC power needs on board.
• 230V/110V Outputs: Each inverter in the series includes combined European and UK outlets, allowing you to plug in standard 230V plugs or UK/US type plugs (110V) – offering flexibility for international usage.
• Economy Mode: The built-in fan and control circuitry optimize efficiency – under low loads the inverter runs almost silently, even entering a power-saving mode (about half consumption) when no load is detected.
• Rugged & Protected: Aluminum casing with full protections against short-circuit, overload, and overheating. Easy to install with battery cables (models up to 300W come with a car lighter plug; higher wattages include cable leads for direct battery connection).

Specialized 7.3 m marine cable for wired remote controls (e.g., EVAL WR6) on boats and yachts. Allows you to install a remote keypad farther from the main device with a reliable, loss-free connection:

• Extends your reach – adds 7.3 m of length between the main unit (stereo, autopilot, etc.) and the control panel
• Compatible with EVAL WR6 – designed for remote control (code 01134) and similar models
• Quality signal – 6.3 mm male-to-male jack connectors provide connection with no delay or interference
• Rugged and flexible – marine-grade cable resists bending fatigue, moisture, and corrosion
• Easy setup – plugs in directly, with no modifications to your devices needed

Flexible plastic corrugated conduit (pre-slit along its length) for protecting and organizing electrical cables on boats, yachts, and vehicles. Made of high-quality polypropylene, this loom shields wires from abrasion, moisture, and chemicals, while its split design makes it easy to insert or remove cables without disconnecting them.
