Variable transformer
ESS 9013
Characteristics
General data
Adjustable ring-core autotransformers of the ESS series are designed for low-loss generation of grid-connected AC voltages. This principle ensures optimal adaptation to the load, resulting in minimal power loss. The design of the current collector ensures continuous reliable contact
Benefits
› Continuous adjustment of alternating voltage from zero to the maximum value
› Self-cleaning of exposed contact tracks
› 4-point flange mounting
› Applicable to three-phase current when mechanically coupling three variable transformers
› Knobs and scales optionally available
