Product Details

The Parallax Power Supply ATS503 is a heavy-duty 50 amp automatic transfer switch designed specifically for RV applications. This robust switch seamlessly transfers power between shore power and generator sources, ensuring uninterrupted electrical service to your RV's systems.

Key Features:

  • 50 amp capacity handles 120/240V power systems
  • Automatic switching between shore power and generator with smooth transitions
  • Industry-leading construction built for reliability and durability
  • Compensates for voltage variations on incoming power lines
  • Simple installation with clear terminal markings
  • Compact design fits standard RV electrical compartments

The ATS503 is engineered to handle the demanding conditions of mobile power management. When generator power is detected, the switch automatically disconnects shore power and connects the generator. When shore power is restored or the generator is shut down, it seamlessly switches back. This eliminates the need for manual power switching and protects your RV's electrical system from backfeeding and voltage issues.

Built with heavy-duty contacts and robust internal components, the ATS503 provides years of dependable service in your RV's electrical system. The switch is designed to handle the full 50 amp load capacity, making it suitable for larger RVs with multiple air conditioners and high-demand appliances.

Will shop here again

The only flaw was that the search engine didn't find my tool. Had to look it up on Google and type in the part number. But still, fast and easy.

Great products and great delivery time

orders come really fast like next day...

Great service and product

Great service

Quick shipment, good price.

I don't appreciate the added offers to "save" money by spending it on things I had no interest in when I bought the car part from you. Would have given 5 stars, but not after being harassed by subsequent ads.

very fast and easy

Quick and Easy. Best price I've seen by far.

great prices

Best prices. Wish you had pics of the back of the gauges.

Thanks

Fast shipping, great price, product was somewhat hard to install but got it done, love the outcome of it. Overall happy.

good service

For this being my fist time using your site. I thought it was a smooth site to shop and find my products and than place my order. I also liked the price.

Good price and very fast shipping.

I saw nothing but good reviews and the money back guarantee, these together helped me finalize my decision to order from this site. I ordered just before the weekend started so I think it took my order a little longer to process. I was relieved to find that my order was shipped on the day I ordered it, It just took a little while for the email traffic to catch up. So far things have been good!!!
