My 4 zone HVAC system needed some 70VA to operate the control board, 5 dampers and 4 thermostats. The old control board and equipment could operated on the 40VA transformer that came with the furnace but the new board took more current. The WR Transformer was a perfect match for parallel installation to provide the extra current needed for the system. I drilled two holes, mounted it and wired it in. Power applied and it worked perfectly as did the entire system. WR makes a good product and this transformer not only worked with 120VAC, but with other voltages as well.

installed it a@ 120vac, connected VOM to output and reading was 35v and not 24v and it was too warm with the malfunction odor. the price was ok so i tossed it rather than the hassle of return and wait etc. i probably got the only questionable one from the entire production line of a million of these. it happens.

The 120/24VAC "plugin" transformer that came with the irrigation control unit kept overheating and tripping the breaker in my breaker box. So I replaced that transformer with this on and put this in my breaker box and ran the 24VAC power to my outdoor irrigation control box. I live in NM and it can get to over 130F inside the breaker box and rhis transformer has run all summer 2017 without issue.

Class 2 refers to a transformer that delivers 100VA or less with a maximum output voltage of 30VAC or less. Class 2 transformers are limited, either by inherent winding impedance or external fusing, to power levels considered safe enough to receive special consideration in safety requirement compliance. It is safe to use equipment even if a protective ground is not present.
