Multi-Purpose International Transformers

Signal Transformer Multi-Purpose International Transformers are ideal for worldwide applications by incorporating international safety features. These MPI transformers improve conventional 50/60Hz transformers with better volumetric efficiency and a solid copper full-width foil electrostatic shield. This series covers five power ratings (from 200VA to 900VA), five primary voltage ratings (from 100V to 230V), and ten secondary voltage ratings (from 10V_CT to 230V_CT). Featuring a 4000V_RMS Hipot dielectric strength and leakage rating of less than 100µA, these high-performance international transformers have achieved an array of agency certifications.
