Isolation More-4-Less™ International Transformers

Signal Transformer manufactures an isolation transformer that lends itself to international safety standards acceptance from UL, CSA, IEC, and CE/VDE conformity. By meeting multiple safety standards at once, end-products using the M4L cost less to qualify for international use, which is why these transformers are aptly named "More-4-Less." These transformers provide more than 12 mm creepage distance between primary and secondary windings with construction and materials that support up to 60°C ambient environments.
