Product Describe：
This product is a core AC distribution control box specifically designed for luxury yachts and medium-to-small vessels. It utilizes a standard
380V/220V AC power supply system and integrates generator (Generator) and shore power (Shore) dual-power input management,
real-time power monitoring, multi-circuit protection distribution, and safety interlock functions. The distribution box is responsible for
safely and stably delivering power to high-voltage and critical equipment throughout the vessel (such as crane control boxes, net lifting
machines, air conditioners, chargers, etc.). Through intuitive digital meters and indicator lights, crew members can keep track of the operating
status of the generator set and shore power system at all times, ensuring electrical safety during navigation and berthing.
Product Feature：
1. Intelligent Dual-Power Switching and Safety Interlock: Equipped with two independent power inputs for the generator (GENERATOR) and shore power (SHORE),
switched via a double-pole double-throw transfer switch in the middle. It features a built-in mechanical interlock function that absolutely prevents the generator
and shore power from being connected simultaneously, eliminating the risk of power back-feed.
2. Dual-Channel High-Precision Digital Meter Monitoring: The left and right sides are equipped with independent digital voltage/frequency meters (V/A/Hz),
which can monitor the voltage and frequency of the generator power and shore power respectively in real-time, ensuring that the input power quality meets
the requirements of the vessel's overall load.
3. Intuitive Audible and Visual Status Indication: The top of the panel features three high-brightness indicator lights (Red - Generator connected/powered,
White - Shore power connected/powered, Green - Main power normal), as well as generator start/stop control buttons, allowing operators to see the status at a glance.
4. Modular Multi-Circuit Safety Protection: The bottom is equipped with a row of high-quality miniature circuit breakers (MCB), specifically providing precise
overcurrent and short-circuit protection for high-power equipment such as crane control boxes (CRANE CONTROL BOX), net lifting machines (NET LIFTING MACHINE),
air conditioners (AIR CONDITIONER), chargers (CHARGER), and outlets (OUTLET), with spare circuits (SPARE) reserved.
5. Industrial-Grade Anti-Corrosion and Moisture-Proof Design: Utilizes a high-strength gray sprayed metal enclosure, equipped with a door lock on the front,
dustproof and splash-proof. Mounting holes are reserved around the perimeter, suitable for flush mounting in yacht engine rooms or electrical control rooms.
