Victron Energy Autotransformer 120/240VAC 32A led light bulb

SKU CH-A0VG-ZGZVK

An autotransformer for step-up, step-down or split-phase balancing at 120/240 VAC and 32 A

  • Autotransformer balances split-phase loads for stable output
  • Steps voltage up or down between 120 and 240 VAC
  • Rated 32 A continuous current for heavy-duty use
  • New condition ensures full factory performance
  • California Proposition 65 warning included for chemical safety awareness

Autotransformer 120/240VAC-32A

The Victron Energy autotransformer handles step-up, step-down and split-phase output balancing for 120 V or 240 V AC systems at 32 A. It suits installers who need flexible voltage conversion in residential or light-commercial power distribution.

Installation requirements and system benefits

The unit connects between a split-phase source and the load to balance neutral current and reduce voltage drop on long runs. It frees the installer from running separate step-up and step-down transformers when both functions are required.

Replaces separate step-up and step-down units

A single autotransformer replaces two dedicated transformers when an installation demands both voltage conversion and phase balancing. The jump is worth it when space, wiring cost or procurement simplicity outweigh the need for galvanic isolation.

Questions about this item

What is the maximum continuous current the 32A autotransformer can handle before its thermal protection activates?

The autotransformer is rated for 32A continuous operation; internal thermal protection will trip if that limit is exceeded for an extended period.

How much audible noise and heat does the autotransformer produce when running at full load all day?

The unit uses passive cooling and operates silently; the enclosure will become warm to the touch at 32A load but stays within safe temperature limits.

Which electrical supply and wiring must already be in place for the 120/240VAC autotransformer to function?

A split-phase 120/240VAC source capable of delivering up to 32A per leg, with correctly sized conductors and over-current protection, is required.
