PowerMax PMTS-30 Automatic Transfer Switch – 30 Amp RV Power Management

The PowerMax PMTS-30 Automatic Transfer Switch is designed to deliver safe and reliable power management for RVs equipped with 30 Amp AC service. When connected to shore power, the PMTS-30 supplies electricity to all AC appliances. If you start your onboard generator, the switch will automatically transfer power after a 20–30 second delay, allowing generator voltage to stabilize before powering your RV’s circuits.

Equipped with heavy-duty relays and a time-delay circuit board, this compact switch ensures that only one power source is directed to your RV’s AC distribution panel at a time—protecting your electrical system from damage. The quick-change circuit board also makes maintenance simple, allowing easy replacement if needed.

Ideal for RV owners looking for a dependable and efficient power transfer solution, the PMTS-30 is lightweight, space-saving, and backed by a 2-year manufacturer warranty.
