Phonovox - Model Serie Am-10 - Reversible Single-Phase Autotransformers for Voltage Adjustment

SHARE
The REVERSIBLE SINGLE-PHASE AUTOTRANSFORMERS from PHONOVOX are designed to address issues encountered when electrical equipment is connected to power networks with different voltages. These dry type autotransformers conform to the EN 61558-2-13 standard, featuring reversible voltages of 125/220 VAC. They are engineered with Class H windings, Class B insulation, and a design suitable for intermittent use without galvanic isolation. Operating at a frequency of 50-60 Hz, they have an IP-20 protection rating and are encased in protective metal covers painted with epoxy resin. Class I classification ensures safety in non-short-circuit conditions. The transformers are available in models ranging from 300 VA to 5,000 VA, with smaller models equipped with metal handles and larger ones with screw connection terminals. Custom power and voltage specifications are available on demand.
