PowerMax PMTS-30LK 30 Amp Automatic Transfer Switch

The PowerMax PMTS-30LK is an automatic transfer switch designed for RVs, boats, and off-grid power applications with 30 amp electrical service. This intelligent switching device automatically manages power transfer between two 120 volt AC power sources, such as shore power and an onboard generator, preventing both sources from entering the AC distribution panel simultaneously.

Key Features:

• Automatic switching between two 110Vac inputs to a single 110Vac output
• Rated for 120 VAC, 30 amp service
• Built-in 20-30 second time delay allows generator voltage to stabilize before transfer occurs
• Heavy-duty relays for reliable operation
• Quick-change circuit board design for easy replacement in the event of failure
• Automatically senses generator power and prevents dual power source conflicts
• CUL listed for use in Canada
• 12 Volt DC relay control

When plugged into shore power, the PMTS-30LK automatically provides AC power to all connected appliances. Simply start your onboard generator or alternative power source, and the transfer switch will seamlessly transfer electrical power to your AC appliances. This unit replaces the earlier PowerMax PMTS-30 model and is ideal for RVs, marine applications, cabins, backup power systems, and off-grid solar installations.
