The Polylux ND250 is a 250VA cast resin covered transformer designed to adapt electrical potentials in industrial systems. It operates at a frequency of 50 or 60Hz and handles input voltages of 230, 400, or 460V, stepping them down to output voltages of 115 or 230V via included metal bridges for voltage selection. Built for Safety class I with IP-20 protection degree, the unit features Class B 130°C insulation and Class HC 200°C windings. It relies on natural air cooling (AN) and mounts securely using screws in an ambient temperature environment of 30°C. Testing voltages reach 4.6kV between primary and secondary, 3.2kV between primary and earth, and 2.5kV between secondary and earth. The ND250 complies with IEC/EN/UNE-EN 61558 and CE standards.
