BIT-150
Electrostatic shield between primary and secondary windings provides cleaner output voltage and helps to reduce spikes and transients. Copper windings connect to connector terminations equipped with NEMA standard holes for compression style or ring terminals. Relative humidity 91%, Class F Class 155°C - 311°F insulation system with 95°C temperature rise at full load and a maximum ambient of 50°C. Transformer standard is IEC 60076, natural air cooled varnish impregnated isolation transformer with double wounded windings. Mode of operation is individual. Highest Voltages of transformer windings are 1.1/3KV and 1.11KV to 12KV insulation at primary and secondary side
