Parallax Power Supply ATS 503 Parallax Power Supply Ats503 120/240v 50 Amp Transfer Switch

The Parallax ATS line generator switches are the strongest in the industry and are the most trusted way to transfer power between shoreline and RV generators. With extreme ease, the improved ATS models transfer power smoothly regardless of the line voltage conditions. Users benefit from not having to handle plugs or electrical cords to transfer power. Parallax offers robust line generator switches specifically designed for 30 amp, 120V and 50 am 120/240V electrical systems. Both models are quality engineered for reliability and performance. ATS 503 sets new standards for 50-amp reliability, ease of installation, and diagnostics for field use. ATS 503 is listed to UL Standard 1008 for 50-amp transfer switches, uperceding the previous UL Standard 508. The printed circuit board design was developed and proven through extensive cycle testing, demonstrating the product's ability to withstand heat and torque. Field reliability is further enhanced by innovative diagnostics and controls. A fault indicator light provides easy trouble shooting, and a manual shut-off for the time delay feature optimizes operation when an inverter is used as the secondary power source.

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!!!
