Customer Questions & Answers

  • Question : What is the primary voltage?
    Answer : 120/208/240
  • Question : What is the secondary voltage?
    Answer : 24
  • Question : What is the VA rating?
    Answer : 40
  • Question : What is the watt/va rating at 120v input?
    Answer : It is rated at 40 VA, 50/60 Hz.
  • Question : Wanting to energize my furnace fan from another thermostat, would this be what I'm wanting to energize the fan when calling for heat?
    Answer : This provides the same voltage that most thermostats use to control their systems. As long as you know what you’re doing, this should power your thermostat.
  • Question : Which wire is the common wire on the secondary, red or green?
    Answer : Either one can be used as it is AC voltage. I always use the green for common as it is ground on AC anyway.
  • Question : Is the output center tapped?
    Answer : This is a non center tapped output transformer.
  • Question : Is this center tapped? Will this divide the voltage into 2 12v rails?
    Answer : No, the secondary has only 2 wires, and outputs 24 volts AC.
  • Question : Will this power an amplifier that needs 24 Volts ac? It needs 300 watts.
    Answer : Need to know more details about your existing transformer ratings, what is the VA required for the existing design? This transformer typically powers Heating/Air Conditioning 24 v circuit for Thermostat and controls. It has multi-tap connection for Primary Voltages of 120, 208, 240 volts, and the 24 v rating is at 40VA this is determined by adding all the control coil relays, solenoids power needs etc. to determine the VA.
  • Question : Does this work on ring doorbell? also, can it accept 240v input? i am planning to use this in european country
    Answer : This transformer converts 240 VAC to 24 VAC or 120 VAC to 12 VAC, so it should be good for using in Europe. The transformer’s voltage and volt-amperage are compatible with the Ring specs.
  • Question : Can i use this to power an ecobee 3 lite from a 240vac line from the breaker?
    Answer : If you connect the orange and white to a 240 ac source, it will step the voltage down to 24 volts AC on the secondary pair of wires. This will only provide 40volt amps so only 0.167 amps.
  • Question : Will one transformer operate more than one uv light for the A/C, or will 2 be required?
    Answer : Your question cannot be answered until you know the uv lamp wattage and voltage. This transformer will handle 40 watts or 1 amp at 40 volts OR 1.67 amps at 24 volts.
  • Question : What does this thing do, I am not an electrician?
    Answer : This is an electrical transformer that transforms the voltage of the electricity from one voltage to a different voltage. It transforms 120 volt’s or house voltage down to 24 volts for electric equipment that only runs on 24 volts of alternating current or AC.

Packard PACKARD - PF42440 Isolation Transformers Editorial Review

If you're looking for a reliable control transformer, the Packard PF42440 is a solid choice. It's rated at 40 VA and operates at 50/60 Hz. The transformer has multi-tap connection for Primary Voltages of 120, 208, 240 volts with a 24 V rating for use with Heating/Air Conditioning 24 v circuit for thermostat and controls. One of the key features of this transformer is its foot-mounted capability, which makes it easy to fit in a variety of settings. However, it is important to note that it is not center tapped and outputs only 24 volts AC. While this transformer has been reviewed and tested by customers, it's always worth double-checking whether it's the right fit for your specific use, particularly when it comes to powering amplifiers or working with Ring doorbells, as some customers have had questions about compatibility.

Pros

  • Multi-tap connection for Primary Voltages of 120, 208, 240 volts
  • Solid 40 VA rating at 50/60 Hz
  • Foot-mounted for easy use in a variety of settings
  • Sturdy/well-made

Cons

  • Larger than some transformers
  • Not center tapped
  • Some compatibility questions with amplifiers and Ring doorbells
