PowerMax PMTS-30 30 Amp Automatic Transfer Switch for RV Marine Off-Grid Applications

The PowerMax PMTS-30 is a relay-based automatic transfer switch designed to seamlessly manage power between two separate 110VAC power sources in RV, marine, and off-grid applications. This intelligent switching system automatically senses and selects the available power supply, ensuring your electrical systems receive safe and appropriate power levels at all times.

Key Features:

• 30 amp capacity with 120VAC, 60Hz input and output
• Dual 110VAC inputs to single 110VAC output configuration
• 12-volt DC relay control system for reliable switching
• Automatic switching between shore power, generator, or inverter sources
• Timer delay function with bypass switch for customized operation
• ETL listed and FCC compliant for safety and performance
• Quick 10-minute installation with no rewiring required
• Three knockout holes (two 7/8-inch and one 1.0-inch) for flexible wiring

The PMTS-30 automatically detects when shore power or generator power becomes available and instantly transfers your electrical load to the preferred source. When the primary source is disconnected, the unit seamlessly switches back to the secondary source without interruption. This automatic operation eliminates manual switching and protects your electrical equipment from power fluctuations.

Ideal for RVs, boats, travel trailers, camper vans, and backup power systems where multiple AC power sources need to be managed efficiently. Backed by a two-year manufacturer warranty.
