This single-phase 400V to 230V<\/strong> isolation transformer offers two key features: it provides substantial galvanic isolation, from 2,500 to 3,000 Volts depending on the version, and it steps the voltage down from 400V to 230V. For medical-use premises, select the \"Medical\" feature in the product specifications.<\/p>\n

These transformers for medical use comply with standard IEC 61558-2-15 and have specific characteristics, such as increased robustness and a higher dielectric test withstand of 4,000V. Medical transformers also feature a temperature sensor and a secondary centre tap, allowing the secondary winding voltage to be divided in two.<\/p>\n

All these single-phase isolation transformers are available in a wide range of power ratings, in bare (IP00) or enclosed (IP2x) versions.<\/p>\n
