Marinco EMS-LCHW50 50A Hardwired Electrical Management System for Shore Power

The Marinco EMS-LCHW50 is a 50-amp hardwired Electrical Management System (EMS) designed to protect your boat's onboard electrical systems from the hazards of faulty shore power connections. Permanently mounted and wired directly into your vessel's AC electrical panel, this unit provides continuous, automatic protection without requiring any action from the operator.

This EMS monitors incoming shore power and guards against a wide range of potentially damaging conditions before they can reach your appliances, electronics, and electrical systems. If a fault is detected, the unit automatically disconnects power and displays a fault code, then automatically reconnects once shore power returns to safe levels.

Key Features:

• 50-Amp capacity for large vessels with high-draw appliances and air conditioning systems
• Hardwired installation — permanently integrated into the vessel's AC panel for a clean, professional install
• Protects against high voltage, low voltage, open ground, open neutral, and reverse polarity
• Automatic disconnect and reconnect — cuts power on fault detection and restores when shore power normalizes
• Digital display showing voltage, amperage, frequency, and fault codes for easy diagnostics
• Monitors both legs of 50-amp (240V split-phase) shore power
• Built-in surge protection to guard against transient voltage spikes
• Suitable for permanent installation in marine environments

The Marinco EMS-LCHW50 is an essential safety device for any boat owner who relies on shore power at a marina or dock. By continuously monitoring incoming power quality, it helps prevent costly damage to inverters, chargers, air conditioners, refrigerators, and other sensitive onboard systems.
