Fonctionnement

Y/Y-connected three-phase isolation transformer with primary winding for 480V and secondary winding for 220V N PE. Magnetic isolation between input and output blocks DC, common-mode noise, and ground-loop currents. Class H insulation handles coil temperatures up to 155 deg C; dry-type air-cooling via cabinet ventilation louvers.
