Guard your large RV’s electrical infrastructure with this hardwired 50-amp surge and voltage regulation system. The microprocessor-driven monitor watches incoming shore power around the clock, automatically shutting down if voltage strays outside the 104–132V range to safeguard climate control, entertainment systems, and power-hungry appliances.

When power is interrupted or a fault condition arises, a built-in time delay allows the air-conditioning compressor to cycle safely before automatic reconnection. Five modes of surge protection cover line-to-neutral, line-to-ground, and neutral-to-ground configurations with near-instantaneous response times.

• 50 amp, 120/240 volt hardwired installation
• High/low voltage protection (104–132V operating range)
• 5-mode surge protection with rapid response
• Reverse polarity, open neutral, and open ground detection
• Accidental 240-volt protection
• AC frequency and fault monitoring
• Remote display with bypass switch for emergency use
• Microprocessor-controlled operation
