Transformers | Understanding Power Needs for Lifting Decks

faqs -> electrical

Q: Why do lifting deck trailers need a stable 24V power supply?

A: Lifting deck trailers require a stable 24V power supply to operate efficiently. This power can be sourced from the tractor unit via an Anderson coupling, on-trailer independent batteries, or from the bay.

Q: What are the different power supply options for lifting deck trailers?

A: The power supply options for lifting deck trailers include:

1. Anderson coupling from the tractor unit
2. On-trailer independent batteries
3. Power from the bay

Q: Why is a transformer needed when using power from the bay?

A: When power is sourced from the bay, it needs to be 415V 32A 3-phase AC current. To convert this AC power to the 24V 300A DC power required by the trailer, a transformer is needed.

Q: What are the advantages of using power from the bay?

A: Using power from the bay has several significant advantages:

• Consistent Power Supply: Quality power can be consistently provided without relying on the trailer's batteries.
• Reduced Risk of Failure: On-trailer batteries, while providing good independent power, are prone to being run down or poorly maintained, which increases the risk of failure. Using power from the bay mitigates this risk.
• Convenience: Trailers can be dropped at a bay and left to operate without concerns about battery life.

Q: What are the drawbacks of using transformers for bay power?

A: The main drawbacks include:

• Size and Weight: Transformers required to convert AC power to 24V DC are quite large and heavy.
• Investment: They represent a reasonable investment when setting up bay power.
