Indicator light on circuit board was not functioning so I immediately knew it was the transformer. After a few voltage tests, I decided to order this. 5 min swap out and my unit works better than before. Review: Awesome quality, price and strength for diy - This transformer is heavier than you might expect. I'd say at least a lbs. That being said it's perfect for the heavy duty transformer that I need. It's weight comes from the great copper windings. This device is not cheaply made. I am using it to push 11 sprinkler valves at one time that run on 24vac and are 110ft away from this transformer. I am using a raspi pi and some relays to be as cheap as possible and have wireless controller where ever I am on the property. The pi has a 24vac to 5vdc transformer and I have no problems at all powering it, and all the valves. This device does not heat up as much as I expected, and I didn't need a star capacitor as the output is a super clean and strong sine wave. All valves open perfectly and strong for over 20 minutes without issue. I saved a ton of money building a DIY sprinkler system and this transformer fulfills all my 24vac electrical needs. ## Features - Mounting configuration: 2 foot - Primary voltage: 120/208/240 - Secondary voltage: 24 - VA rating: 40 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01HPJT7C0 | | Best Sellers Rank | #59,520 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Isolation Transformers | | Brand | Packard | | Brand Name | Packard | | Customer Reviews | 4.6 out of 5 stars 965 Reviews | | Global Trade Identification Number | 00719006520015 | | Item Dimensions D x W x H | 4.1"D x 4.1"W x 4.1"H | | Item Weight | 0.01 Pounds | | Manufacturer | PACKARD INC. | | Model | Packard PF42440 | | Mounting Type | Foot Mount | | Part Number | PACKARD - PF42440 | | Power Source | Corded Electric | | Product Dimensions | 4.1"D x 4.1"W x 4.1"H | | Specification Met | UL | | UPC | 719006520015 719006520183 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Packard - **Mounting Type:** Foot Mount - **Power Source:** Corded Electric - **Product Dimensions:** 4.1"D x 4.1"W x 4.1"H - **Specification Met:** UL ## Images ![Packard - Packard - PF42440 Control Transformer Class Ii Foot Mount, 40V/24V - Image 1](https://m.media-amazon.com/images/I/51DaYoOZN8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed my broken HVAC UNIT *by S***N on August 28, 2023* Easy swap out.
